Slurry Seal Life Expectancy

Slurry Seal - PPRA

In doing so, it is important to understand the life expectancy of the slurry seal decreases as the distress severity increases. Optimal slurry seal performance occurs when the treatment is applied before existing pavement distresses become too severe or widespread. Many agencies have reported 8 years or more of service life when slurry seal is installed on newer pavements in good condition ...

Asphalt Seal-Coat Treatments

The sand seal generally provides a thicker coating on the pavement surface than the fog seal, resulting in a longer life expectancy. The sand seal on polished aggregate surfaces can provide additional skid resistance. Disadvantages Only fine cracks are filled and larger cracks tend to reappear within a year. Figure 4—Sand seal. (Photo courtesy of Western Emulsion.) Equipment The equipment ...
