It’s a Bird! It’s a Plane! No…It’s a Drone!

Drone Technology and the Paving Industry

Drones, or Unmanned Aerial Vehicles (if you want to get fancy with it) are hovering high these days. They can be found zooming around parks, crop dusting over farm fields, and swooping in to capture wedding parties as they stand smiling blindly into the sun. They are even becoming big players (or flyers) in the world of paving and concrete.

So Many Pretty Pictures!

The earliest and most basic use of drones in the asphalt and concrete arena was for marketing and documenting purposes. The ease of sending a drone up to take recorded images of the before, during, and after transitions of a project has served the industry well in regards to identifying needs and giving a nice visual of the completed work. But they have quickly evolved into so much more.

Exactly How Big is that Pile of Rocks?

Perhaps the biggest impact of drone technology as it applies to asphalt and concrete is at the aggregate plants. Estimating materials needed used to be a labor intensive and dangerous proposition and was never entirely accurate. It was a little more sophisticated than a guy measuring it out by the bucketful, but it still involved a fair amount of manual labor, math, and good old fashioned hill climbing. Drones have transformed this process by monitoring volume and contours of stockpiles from the air using sophisticated software. They are also increasingly used in conjunction with daily walkthroughs, identifying heat changes, gas leaks, broken equipment, and more from their bird’s eye vantage point.

No More Guy with a Shovel.

We’re lucky to not have to deal with too many potholes in the Bay Area, but in other parts of the country the constant freeze and thaw can wreak havoc on the roadways. Researchers in England have come up with drones which not only take images of the roadways to identify problem areas, they are also equipped with 3D printers and an extruder to land and fill the cracks and crevices on the spot. This means the stretch of road can be assessed and repaired in a matter of hours rather than days. The timely repairs ease traffic hassles and also increase the lifespan of the road.

But What About Pizza?

It’s all fascinating stuff, and we are anxious to see how drone technology and other advances in the industry will enhance what we do day to day. To be honest, we are mostly just waiting for drones that will show up on the porch with a piping hot pizza…. In the meantime, you can rest assured Black Diamond Paving & Concrete will continue to shine in the basics, providing expertise, attention to detail, and superb customer service with every project we undertake.

Nanotechnology and Asphalt

The Teeny Tiny Bits of Stuff that Make Pavement Better

nan·o·tech·nol·o·gy
ˌnanōˌtekˈnäləjē/
noun
1. the branch of technology that deals with dimensions and tolerances of less than 100 nanometers, especially the manipulation of individual atoms and molecules.

What does the egg that slides from your frying pan, the tennis ball you bounce to your pup, the sunscreen you slather on at the beach all have in common with the roads you drive on? You’ve guessed it—nanotechnology.

Put simply, nanotechnology is a process in which individual atoms and molecules are manipulated. To give you an idea of scale, there are approximately 25 million nanoparticles per inch. We’re talking TINY. How can something so small make such a big difference? Let’s take a look at the roles nanoparticles play in the world of asphalt:

Nanoclays

Asphalt is made up of finely ground materials, mixed with a binder which is heated and then applied over a compacted base. The use of nanoclays—super teeny tiny bits of layered mineral silicates—added to the binder mix can increase the viscosity of the material, making it easier to pour and spread. Once cooled, it has the effect of enhancing the compression and resilience qualities of the asphalt by making it less brittle, which means less cracking and crushing.

Nanoirons

The addition of nanoparticles into asphalt can also positively impact pavement maintenance. For instance, research is underway into self-healing roads using iron nanoparticles. In this application, iron nanoparticles are infused into the binder, and when the sun, ice, rain, and general wear and tear creates micro cracks, a specially designed machine emitting a magnetic field can be moved over the surface, heating the binder and healing the cracks. This technology could double the life span of roads and turn repairs into an hours long scenario, rather than weeks long.

Nanosilicas

The use of nanomaterials stretches far beyond just making paved surfaces more durable. They can be used to increase safety features, as well. Skid resistance is the highest factor in evaluating surface safety. The use of nanosilica (silicon dioxide nanoparticles) in a top coating can reduce skid factor and serve to cut down glare and road noise.

Nanophosphorous

Do you ever have trouble seeing the pavement markings on a dark and rainy night? By augmenting the line markings with phosphorus materials, visibility factors are increased and improved.

There’s a lot on the horizon with asphalt technology. At Black Diamond, you can be assured we are keeping up with the latest research and trends in our ongoing effort to giving you the best customer experience and longevity of surfaces possible.

Interested in Interlayers?

The Magic Mesh Material that Helps Curb Cracks

Crocodile skin may be hot, hot, hot when it comes to fashion, but it’s significantly less desirable when it’s your pavement that begins to look reptilian.

Even with routine maintenance, cracks can appear and begin to take over in an invasive spread. Since asphalt is brittle by nature, temperature fluctuations, soil shifts, and traffic can wreak havoc both on top of and under the surface, creating what are called reflective cracks. You can do a simple overlay of asphalt to provide some temporary measures, but for a more thorough (and less costly in the long run) fix, consider application of an interlayer.

Made of a mesh type fabric, interlayers are known by a few brand names such as Petromat, GlasPave, and TruePave, but they all essentially work the same. They add a slightly more flexible, stress-absorbing and moisture-resisting barrier between your old and new surfaces.

The process is relatively simple:

  • A light coat of asphalt is applied on top of the old asphalt to fill in cracks and make the surface smooth again.
  • The fabric is then laid on the new asphalt coat. Full saturation with asphalt oil is critical for lasting strength and support.
  • Finally, a new layer of asphalt is applied to top things off. The saturated fabric is strong enough to keep the cracks underneath from permeating the new upper layers of asphalt.

If you’re experiencing just a few problem areas of asphalt, rather than across the full surface, this fabric can be applied in those areas as needed. Be aware, however, that any existing cracks from the non-interlay surface can eventually migrate their way over to new surfaces.

Whether you’re interested in fixing problem areas or your desire is to limit the number of cracks and severity of cracking in the future, interlayers can provide a great solution.

VILLAGE IN THE PARK – PROJECT UPDATE

Village In The Park HOA

Monday 10/ Updated 4:10pm – UPDATE FOR YELLOW SECTION RESIDENTS – TRASH Pick Up and Overnight Closure.  

Residents who live in the Yellow Section on Treeview from the intersection of Foxhollow to Rampart.  The road within your area will remain closed overnight until tomorrow evening.  Trash trucks will not be able to enter this section tomorrow morning as it will be unsafe for them to drive over the exposed road interlayer material.  If you would like to have your trash picked up, you will need to stage your trash bins at one of the two trash pickup points.  See Map below – Trash points are marked in Red at the Yellow boundary points.

All Residents within the other sections the roads will be open.

 

Speed Bump Replacement: This will take place tomorrow as the crews works to complete the yellow section overlay, a smaller group will brake off and begin with the speed bump installs.  Please remain flexible as the immediate area where the bumps are being placed may be temporarily blocked to through traffic, thus please plan for a slight delay and use an alternate route.

 

STRIPING:  Another reminder that all parking areas which need to be re-striped will be closed on Wednesday 10/10.  The parking areas will re-open once the paint has dried.

 

Thank you for your patience and understanding, we are almost done!

Concrete: The Modest Material With a Rock-Solid Reputation

What Can Concrete Do for You?

From roadways, sidewalks, and curbs to fancy pool decks and retaining walls, concrete can be found in nearly every urban and rural setting across the country. And with good reason! It’s versatile, it’s durable, it’s economical…it really has a rock solid reputation, and we thought it was about time you got to know it a little better.

First, a Bit of History

  • January 11, 1900: Thomas Edison applied for his first patent concerning concrete. Over the next 17 years, he would apply and receive 49 concrete patents—for crushing and screening, conveyors, sealing, and more.
  • 1909: In Detroit, the Wayne County Road Commission (of which a guy pretty invested in roads—Henry Ford—was a member) completed the first concrete road, which was a whole mile long!
  • 1922: The Edison Portland Cement Company poured the concrete for Yankee Stadium. When the stadium was renovated in 1973, the concrete walls were left untouched. They’d held up beautifully for more than 50 years!

But, How (You Might Ask) is it Made?

You’d be hard pressed to find a more humble material. Composite materials such as sand and gravel are mixed with a fluid paste (cement) and water. Rather than simply drying to its rock-like final form, the mix goes through a series of chemical reactions due to the lime content in the cement portion of the mix. This curing process, which takes place over a series of hours, or even days, allows the concrete mix to be transported, poured, smoothed, and perfected.

Why Concrete? (We Know You’re Dying to Find Out)

The benefits of using concrete are numerous and varied. For a start, it’s highly water and fire resistant. Unlike wood or metal, concrete does not rust or decompose. Whether the desired project is strictly utilitarian or decorative, concrete can be molded and poured into any shape imaginable, and reinforcing materials, such as rebar, can be added. In addition to its tough-guy qualities, concrete holds the top prize for aesthetic options, as it readily accepts tints, sealers, texture stamping, and more for an aesthetically appealing finish. Concrete holds its own in terms of durability and longevity and, although the initial costs may be higher than other materials, it’s often more economical over the course of its life span.

Here at Black Diamond, we spend nearly as much time as Edison thinking about concrete. (It is half our name, after all.) Whether you need a pool deck that’s smooth and easy on the feet, shiny new sidewalks and curbs, or repairs to existing concrete surfaces, we are ready to get started. Give us a call! (We’d love to cement our—and our concrete’s—reputation with you!)

Curb Appeal: It’s All About Routine Maintenance

First impressions are important, which is why property owners pour effort and money into beautiful curb appeal. Well-maintained structures, landscaping, and shared common areas all contribute to the property looking its best. But what about your asphalt and concrete surfaces? Do they enhance your property or take away from the overall aesthetic?

There are several culprits which can affect the surfaces your visitors and residents walk and drive across each and every day. Sunshine, drainage issues, root formation, fluid build up, and general wear and tear all contribute to the slow formation of cracks and dips in the surface and overall deterioration of your pavement. These flaws are not only damaging to the visual impression your property makes, but can also be dangerous to pedestrians and vehicles.

There are a few minor things your landscaping or maintenance crew can do to keep your asphalt and concrete exteriors tidy:

  1. Take the time to manicure the edges and create a clean definition between the surface and the grass or landscaping.
  2. If there are any weeds creeping in, have them pulled or sprayed.
  3. Give the expanse a thorough hosing off to remove excess dirt and debris that accumulates on the surface.
  4. Examine the neighboring surfaces to ensure you do not have any areas that will contribute to pooling or draining issues, which can further deteriorate the surface.

Next, take a look and assess any structural issues that need to be addressed. Depending on where your pavement is on the Pavement Life Cycle, it may benefit from professional maintenance.

Stage 1: 0 to 5 Years

If your pavement is relatively new, you should be good. Unless you notice any problems, scheduling maintenance for your brand new pavement is often a waste of time and money.

Stage 2: 5 to 7 Years

This is what we like to call the “Initial Preventive Maintenance” phase, and typically only involves minor (but important) procedures. If your pavement falls into this category, you can expect we’ll recommend an initial sealcoating and possibly some crack sealing, if needed.

Stage 3: 7 to 15 Years

This is the “Minor Repairs and Continued Preventive Maintenance” phase. Typical maintenance procedures during this time in your pavement’s life include some patch repairs, crack sealing, and a second sealcoating.

Stage 4: 15 to 25 Years

It’s at this stage where you’ll start to experience some major repairs. Your pavement is no longer a spring chicken, and you’ll need to look into sprucing it up with extensive patching repairs, possibly an asphalt overlay, and a third sealcoating. (Why so much sealcoating? We wrote a series on the importance of this particular maintenance procedure—give it a read to learn exactly why it’s so crucial to extending the life of your pavement!)

Stage 5: 25 to 35 Years

This is basically the end of your pavement’s life, and you can expect to have extensive repairs done throughout the community. Often, especially if you’re toward the end of this age range, it makes most sense to undergo a complete removal and replacement of the asphalt.

So, where is your property on the Pavement Life Cycle? How curb-appealing are your asphalt surfaces? Is it time for a sealcoat? Do you have any cracks, crevices, or crumbles that need attention? Are there patches that should be addressed?

If the answer is “yes” to any of those questions, or even if the answer is, “I don’t know,” Black Diamond can help you determine the condition of your pavement and make a plan for getting things back in shape and keeping your property safe, beautiful, and inviting.

The Never Ending Life of Asphalt

Oh, the stories it could tell. The humble surface you drive on, play on, and walk on has likely had a previous life—maybe two or three. Asphalt has the honor of being the most recycled material in the world, with 80% of it being reclaimed and 100% of the reclaimed material being recycled. Here’s how the process for reclaimed asphalt pavement (RAP) plays out every day across the US:

When an asphalt surface is replaced or resurfaced, layers are removed through a process called milling (this is a fancy way to say the surface is broken up into removable bits and chunks). The material is then transported to a recycling facility where it is fed through a machine that further crushes all the bits and chunks and screens them for uniform size. Additional materials can also be recycled and integrated, such as shingles, ground tires, and pig manure. (Why pig manure? It’s been found to have natural oils that mimic petroleum, thereby reducing the use of new petroleum products.)

Next, this mix is heated and tumbled, which helps to rejuvenate the liquid asphalt binders and reduces the amount of new binders needed. When the mixture is nicely mixed and up to temp, it’s ready to go back out into the world looking shiny, new, and stronger than ever.

Integrating RAP technology into asphalt projects helps to save thousands of acres from landfills, reduce the carbon footprint of materials used, and conserve raw materials each and every day.

Pavement Got You Cracking Up?

Common Asphalt Issues and How to Identify Them

As pavements age, common asphalt problems, like cracks and depressions, tend to rear their ugly heads. With any kind of asphalt damage, it’s important to understand the underlying issues, so you can better understand how to fix, and ultimately avoid them. Do you know what to look out for? Below are some of the issues we see most often:

 

Alligator Cracking

Alligator Paving TermAs the name suggests, these cracks tend to look like the rough, patchy skin of an alligator. They typically occur when the pavement structure is poor—a weakened base or surface is often the culprit. It’s best to deal with this issue as soon as you notice it; parking lots with minor alligator cracking can be overlaid with a new layer of asphalt, but if left too long, water penetration can lead to more widespread cracking, potholes, and eventually general pavement failure. Once it gets to this stage, more cost-effective maintenance procedures, like crack sealing and overlays, will NOT be an option. A full removal and replacement will be in order…ouch!

 

Potholes

We’ve all experienced those pesky potholes, whether on the road or in our own driveway. This problem can be caused by poor drainage and heavy freeze-thaw cycles. Luckily, we don’t get too much of that in California, but that doesn’t mean potholes don’t pop up from time to time. It’s important to repair these guys as soon as possible in order to prevent further damage…to your pavement and to your tenants’ wheels!

 

Block Cracking

These cracks often look like large, rough, interconnected rectangles (or blocks) and are typically caused when poorly mixed asphalt is laid in an area that experiences frequent temperature changes. Asphalt will shrink and expand when exposed to the elements, but if the pavement can’t keep up…you get cracks.

 

 

Depressions

Water Raveling ErosionThese are low, localized areas on the surface of the asphalt, and are typically formed by sub-bases that become uneven over time. These areas end up holding water, which can cause even more issues, like potholes and pavement failure.

 

 

Many of these problems are part of the normal lifecycle of your pavement, but with repairs and preventive maintenance, your asphalt can last for many years without having to undergo major repairs. If you are noticing any of these problems on your asphalt surface, give us a call! We can help assess the damage and come up with a solution that fits your needs.

What to Look for When Hiring a Contractor

Hiring a pavement maintenance contractor—or any contractor for that matter—can be taxing for a property owner or manager. That’s because the problems you need solved and the work you need done can be costly, time-consuming, and potentially disruptive to tenants and communities. So, it’s important to ask the right questions when making your hiring decision. Here are some tips:

Ask to See a State License.

In most instances, contractors must be licensed by the state, so confirm that the contractor has completed this step.

Ask for Proof of Insurance.

In this day and age, no contractor should be without insurance—both for their protection and for yours.

Look for Longevity.

Just because a company has been around for years doesn’t guarantee quality work and a good working relationship. But the odds are in your favor if the company you hire has been around for awhile.

Check References.

Any contractor worth his (or her) salt will be happy to provide references for you. Take the time to make a few calls.

Visit the Contractor on a Jobsite.

Contractors are always working, and you can gain insight into their work process by watching them on someone else’s job before you sign on the dotted line.

Spend Some Time on Their Website.

A good website doesn’t assure a quality job or contractor (just like a great website doesn’t guarantee it, either). But a few minutes spent online will give you additional insight into services they perform, jobs they’ve done, and possibly some comments from their customers.

Check out the Company’s Better Business Bureau Rating.

This shouldn’t necessarily rule in or out a contractor, but more knowledge is better.

When you’re ready to hire a contractor for your next paving or concrete job, give us a call! We’ll be happy to give you all the details necessary to make the best, informed decision for your property.

Sealcoating 101: Part 4

When – and How Often – Should You Sealcoat Your Pavement?

Designed for use on off-highway pavements, sealcoating is the lowest-cost weapon in your pavement maintenance arsenal. When used properly and in a timely manner, it can also be the most effective option.

Pavements should be sealed as soon as possible after a new hot mix asphalt surface has been constructed. But “as soon as possible” means different things in different areas. That’s because newly placed asphalt mix must be allowed to cure—the asphalt’s oils must be allowed to dry out—before a sealcoat is placed on top.

Sealer applied too soon will look good and will be effective in protecting the pavement, but it won’t last as long. The oils trapped beneath the sealcoat will eventually work their way out, and the sealcoat could fail prematurely. Time and weather have the greatest impact on how quickly your asphalt pavement cures, so your contractor will have the best insight into when newly sealed pavement should first be sealcoated.

Once your pavement is sealcoated the first time, it’s important to continue that process. Air, weather, sun, and traffic all work to wear sealer away so, generally, sealcoating every three years is recommended. But in some locations—high-traffic roads, exceptionally busy parking lots, bank and fast-food drive-thru lanes—sealer might wear more quickly and might need to be sealcoated more frequently. Applying an additional coat (or even two) of sealer to these heavily trafficked areas is one way to protect them longer, and your contractor can best make that recommendation for you.
