Why Seal Coat ?

All Asphalt Oxidizes and Deteriorates

Page 9: Resurfacing (Seal Coat) Program 2015

With time, weather and changes in temperature

Page 10: Resurfacing (Seal Coat) Program 2015

Asphalt dries and cracks

Page 11: Resurfacing (Seal Coat) Program 2015

Pavement rapidly degrades after cracking starts, and then water

infiltrates

Page 12: Resurfacing (Seal Coat) Program 2015

If left untreated, all asphalt streets eventually pothole

Early treatment is cost effective

$1 for preventative treatment here

Prevents spending $10 - $15 to fix this
