HIGHWAY TECHNET VIRTUAL EXPO PAVEMENTS INDEX Asphalt Pavement Design and Construction Where the Rubber Meets the Road DP-87 Drainable Pavement Systems (Phase II) |
|
The asphalt pavement design and construction technology group focuses on innovative techniques for design and construction of high-performance asphalt pavements used in new construction, reconstruction, rehabilitation, restoration, or resurfacing. The Federal Highway Administration (FHWA) continues to support performance-related specifications for highway construction. Performance-related specifications (PRS) require materials and construction tests, the results of which correlate to a known degree with the performance of the completed product. A series of FHWA, National Cooperative Highway Research Program (NCHRP) and State Planning and Research (SP&R) studies have produced the initial framework and at least a partial system of PRS for hot mix asphalt pavement construction. The focus in the PRS is on quality control of construction-selecting the best available materials, and establishing the mix and pavement designs. PRS addresses three questions:
