What is Sealcoat?

Page 3: Williamson County, Tx Seal Coat Program 2014

Sealcoat is a thin layer of liquid asphalt

Page 4: Williamson County, Tx Seal Coat Program 2014

Covered by a thin layer of aggregate

Page 5: Williamson County, Tx Seal Coat Program 2014

That is rolled and pressed in place

With loose surface aggregate swept up after 24 - 48 hours

and cures into a tight, dark surface

Why Seal Coat ?

All Asphalt Oxidizes and Deteriorates

Page 9: Williamson County, Tx Seal Coat Program 2014

With time, weather and changes in temperature

Page 10: Williamson County, Tx Seal Coat Program 2014

Asphalt dries and cracks

Page 11: Williamson County, Tx Seal Coat Program 2014

Pavement rapidly degrades after cracking starts, and then water

infiltrates

Page 12: Williamson County, Tx Seal Coat Program 2014

If left untreated, all asphalt streets eventually pothole

Page 13: Williamson County, Tx Seal Coat Program 2014

Early treatment is cost effective

$1 for preventative treatment here

Prevents spending $10 - $15 to fix this
