PAVEMENT DAMAGE FUNCTIONS FOR COST ALLOCATION VOLUME 2 DESCRIPTIONS OF DETAILED STUDIES

Pavement damage functions were developed for both flexible and rigid pavement distresses that were considered significant as generators of major repair or rehabilitation. These damage functions were then used to develop load equivalence factors for each of these significant distresses. The result of this is a family of damage functions or distress models for broad application for pavement management and other uses as well as for cost allocations. These were discussed in Volume 1 of this report. Volume 2 provides descriptions and details of studies conducted in support of the developments reported in Volume 1. The majority of Volume 2 reports the results of laboratory testing of material samples from flexible pavement test sections in New York, Texas, Florida, Louisiana and Colorado, and the characterization of material properties for the VESYS III-B flexible pavement model. The testing included repetitive load testing and indirect tensile tests, as well as conventional material testing. The materials characterizations included fatigue life potential for asphalt concrete, stiffnesses of the component layers of the pavement structure, and permanent deformation potential for the component layers. Other detailed studies discussed were development of traffic and axle-load distribution data for flexible pavement test section studies, improvements to the VESYS model, and development of damage models for jointed plain and jointed reinforced concrete pavements.
