This report explores recommended practices for the design and construction of permeable friction courses (PFC) and examines PFC maintenance and rehabilitation.

Aggregate used in hot mix asphalt (HMA) must be tough and durable, not only to withstand the effects of HMA production, transportation, and construction but also resist the effects of traffic and the environment. The objective of this research was to characterize ...

Aggregates to be utilized in hot mix asphalt (HMA) must be both tough and durable. Aggregates must withstand the effects of HMA production, transportation, and construction. Additionally, once placed on the roadway, aggregates must also resist the effects ...
