Crack Sealing: Effectiveness

Description: A short, one year performance evaluation was made of four crack sealing products. The products: (1) CRF manufactured by the Golden Bear Division of Witco Chemical Corporation; (2) Flex-a-Fill manufactured by Deery Oil; (3) RoadSaver 221 manufactured by Crafco Incorporated; and (4) a sand slurry mixture designed by the Washington State Department of Transportation.

The two rubber-asphalt products, Flex-a-Fill and RoadSaver 221, performed better that the other two products, which used an emulsified cement as a base.
