Water is an amazing and powerful force, essential to life.  But it’s also the primary agent of entropy for other materials, eroding way surfaces or getting inside them and damaging from the inside out.  Given enough time, a smooth surface can become like the Grand Canyon, just from the power of water. 

While the Grand Canyon might be awe-inspiring, this same force applied to a surface you need to remain smooth can be a real issue.  You certainly don’t want your driveway or business parking lot to have anything in common with that craggy canyon!  Fortunately, we here at Wolf know how to keep water damage at bay.

Protect Against Water Infiltration

Here at Wolf Paving, we care about ensuring our work is the very best it can be and that it lasts as long as possible. To achieve the best results, we carefully consider every aspect of a paving project, literally from the ground up. What kind of soils exist at the site? If paving has been done before, what materials were used and are they re-usable in the current project? We ask these questions because we know an excellent base is required for an excellent result. A weak base could result in the pavement above it shifting, cracking, or even sinking. 

How do you keep roads and parking lots in good condition cost-effectively?  We’ve already talked about many of our routine maintenance suggestions, such as filling in cracks and sealcoating, but sometimes a surface is too damaged for these small actions – in these cases, it would take more money and time to repair than it would to perform a full rehabilitation.  But asphalt pulverizing offers a very economical way to fully rehabilitate a road or lot with minimal traffic disruption. It’s also a great way to save on paving materials. 

What is pulverization?

Pulverizing is a process that grinds up existing surface layers right in place, blending the asphalt layers with any sub-layers, essentially creating a new paving mix using all the old materials. No pavement is hauled away, saving costs on excavating and trucking, and rarely does new material have to be brought in (though sometimes additives or a new overlay are suggested).  Asphalt pulverizing solves most common problems, such as severe cracking and sharp edges created by continuous traffic (called “polishing”). 

Perpetual pavement is a flexible but strong asphalt pavement that doesn't exhibit structural damage even when very high traffic flows over long periods of time. They’re made up of multiple layers of durable asphalt. The bottom layer is designed to be strong but flexible to resist strains that could cause cracks to form from the bottom up. A similar intermediate layer adds additional structural protection, and the final layer, made of rut-resistant hot-mix asphalt (HMA), requires only minimal maintenance. 

These surfaces have been around a long time. Some of the oldest perpetual pavements have been around since before the 1960s. The surfaces created then that were well designed and executed have provided very long usefulness without much maintenance even with heavy traffic. These days, advancements in milling, recycling, and asphalt production technologies make it even more likely that perpetual pavements will perform better and longer.
