Pavement Maintenance
The nature of asphalt & the necessity of periodic, preventative maintenance
Asphalt pavement is composed of aggregate of various sized stone, sand, and a binding element, known as asphalt cement. The asphalt overlay functions as a "cover" for the overall pavement design. As the strength and stability of the foundation determine the overall life and performance of any traffic bearing surface, a durable, resistant top layer is as necessary in order to shield the underlying base from water penetration. Yet, it is just as imperative that the binding element maintain its flexibility to endure temperature changes.
The deteriorating effects of weather, oxidation through sun exposure, and harsh chemical deposits from leaky automobiles over time break down the binding property of the asphalt cement. The result is unraveling of the pavement, or an "alligator" effect, leaving the sub-base vulnerable to water penetration.
Seal Coating
Our seal coating process forms a waterproof, resilient layer of protection creating a barrier against the degenerative effects of time, weather and harmful chemicals.
It is preventative maintenance which serves to protect your original investment.
The application of seal coat:
- Seals in the vital binding element of the asphalt mix, preventing pre-mature breakdown of its structure
- Acts as a wearing coarse for the overall pavement design
- Protects the original investment of the new pavement by substantially increasing the life of the pavement, and reducing the need for costly repairs or untimely resurfacing
Crack Filling
Open cracks and joints in pavement can result in extensive pavement repairs. Leaving these voids exposed over time results in new crack formation at an accelerated rate. By sealing cracks and joints, the penetration of surface water, stones, and sand into the pavement's sub-base is restricted, maintaining its structural capacity and preventing further degradation.
