Abstract:

The researchers investigated the effects of several influencing factors on the performance of seal coats based on a thorough literature review and a survey of TxDOT and other state DOT personnel. They evaluated tests that could be used to measure the binder-aggregate compatibility and adhesion. The study used modifications of a Sweep test and Vialit test to measure seal coat aggregate adhesion, and researchers performed these tests in multiple experiments to investigate the effects of binder type, dust, REOB and PPA, and liquid antistrip agents on adhesion characteristics using four different aggregates' mineralogies. They also evaluated more than 30 field test sections for loss of texture after one to two years in service, observed their general condition, and conducted Vialit and Sweep tests on material retained from construction.
