Title: Field Performance of Porous Friction Surface Course
Abstract: The purpose of this study was to develop laboratory mix design procedures for PFC mixes and to prepare PFC construction specifications. The first phase of the study was a three-element program to determine the applicability of PFCs for airport surfacings. The first element was a literature survey to establish a state of the art for PFC mixes. The second was the observation of the construction and performance of PFCs at a number of airports and airfields to determine the construction procedures and pavement characteristics that result in the best performance. The third was a laboratory study to identify the material characteristics of aggregates and bitminous materials that correlate with field performance and to establish procedures for designing PFCs. The second phase consisted of additional performance studies and laboratory testing to improve the mix design procedures and construction specifications. Among the principal findings were that PFCs should be used only on structurally sound flexible pavements (base pavement cracks will reflect through the PFC relatively soon and subsequently ravel) and that the best performance will be obtained from PFC mix design using the same aggregates and asphalts as the base pavement.
