Abstract:

Numerous factors, including aggregate characteristics, construction variables, traffic volume, and environment, are believed to affect the frictional performance of highway pavements. In this research, the effects of these factors on the field frictional resistance of seal-coat surfaces are investigated. The investigation reported here involved establishing seal-coat test sections in different climatic regions in the state of Texas with various aggregate types and sources and under different traffic volumes. Samples of the aggregates used were examined in the laboratory to determine their physical properties, polish and wear characteristics, resistance to weathering, resistance to impact and abrasion, and petrographical and mineralogical qualities. Field tests for measuring friction and texture are being performed on the surface of test sections twice a year at random intervals. Probabilistic prediction models resulting from the study will provide an engineering solution whereby the frictional life of a seal-coat surface can be predicted or the characteristics of the aggregate required to maintain a given level of frictional resistance can be determined during the design phase.
