PATCHING & MAINTENCE
Patching is the process of filling potholes or excavated areas in the asphalt pavement. Quick repair of potholes or other pavement disintegration helps control further deterioration and expensive repair of the pavement. Without timely patching, water can enter the subgrade and cause larger and more serious pavement failures.
Asphalt sealcoating involves sealing asphalt cracks to prevent ice and water from entering and disturbing the integrity of your driveway or parking lot. Over time, rain, oil and other chemicals degrade asphalt, creating a brittle surface that is both unsafe and unattractive.
There are primarily five types of pavement sealers.
These are commonly known as:
Refined tar-based (coal tar based)
All five have their advantages and disadvantages, but are typically chosen by th’ preference unless otherwise specified.
