Design, Construction, and Performance of Bituminous Seal Coats
The report describes a field study that was conducted at The Pennsylvania State University Pavement Durability Facility (test track) and on Route 64 to determine the effect of specific construction, traffic, and materials variables on the performance of bituminous seal coats. Condition of the existing surface (worn or leveled), emulsion application rate, rolling patterns, time between construction operations and opening to traffic, and polymer modification were among the study variables. Traffic was applied to the sections for 1 year, and the performance, skid resistance, visual evaluations, and mean texture depth were documented. Design and construction variables were found to diminish the other study variables. The report includes recommendations for improving the PennDOT design procedure, suggestions regarding quality control, and a tentative model for predicting seal coat life.
