Abstract

The objective of this research was to develop testing protocols to evaluate and rank asphalt pavement sealers to produce a qualified product list. Two parameters, wet track abrasion resistance and permeability, were used to evaluate the sealers in the laboratory. The wet track abrasion resistance of aged specimens was used to determine the potential longevity of the sealers. Sealers with higher resistance should stand up to more prolonged wear from traffic loads. The permeability was used to determine the potential sealing performance of the sealers. Sealers with greater reduction in permeability should better inhibit pavement’s damage from intrusion of air, water, or liquids. Test specimens were prepared, aged, and tested for each of several sealers using the test protocols developed. The results fell into distinct groups, allowing the sealers to be ranked to produce a qualified product list. Future research is needed to validate the laboratory results in the field.
