While asphalt pavement is designed to be flexible, ground movement or thermal expansion/contraction cycles may create more movement than the pavement can withstand. This excess movement ultimately results in some form of pavement cracking.
If left untreated, pavement cracks will widen, allowing water to channel and damage the pavement base. A compromised base will quickly lead to fissures, gaps, and pavement deterioration, such as voids, potholes, raveling, and more. Sealing new cracks on a regular basis can drastically slow pavement deterioration.
ASPHALT CRACK REPAIR (CRACKS <1.5″ WIDE)
Crack repair is the single best thing you can do to extend the life of your asphalt and yields the highest return on your investment. Studies have shown that for every $1 spent on crack sealing, $6 will be saved on future asphalt repairs & restoration. Correct preparation of the asphalt crack is the key for long term results. We use a Crack Jet II heat lance machine to open up, clean and prepare the cracks before the hot pour crack sealant goes in (Click on the video to see the Crack Jet in action). This technology generates extreme hot air (2,800 F) and is blown into the crack at high pressures (90 CFM). It will clean out any debris/dirt/vegetation, dry and heat etch the inside walls of the crack. The “heat etching” creates grooved fingers along the inner walls of the crack which provides an excellent surface for the sealant to bond with the asphalt. We follow up with our contractor grade Hot Pour Crack Sealant (applied at 375-400 F). Once the material sets up, it will eliminate water from penetrating and remain flexible across all climate conditions. This detailed preparation results in a repair that can last twice as long when compared to other conventional methods (wire wheel, line trimmer, brush, compressed air or blower).
