Moisture damage in asphalt pavements is a complex phenomenon affected by a variety of factors, and has not been fully understood, with major knowledge gaps in three areas: major factors contributing to moisture damage in the field, appropriate laboratory test procedures, and the effectiveness of...

Truck traffic information is one of the key inputs in the design and analysis of pavement structures. Until relatively recently, truck traffic data typically were aggregated into equivalent repetitions of a standard axle load for pavement design. The mechanistic pavement design procedures being...

This report provides a summary of the results of the various studies completed in the Partnered Pavement Research Program (PPRC) during the period 2000–2004. In addition, preliminary findings of investigations, initiated but not yet implemented during this period, are included. The...

A brief review of some studies undertaken reveal that direct relationships between DCP penetration and R-value are not reliable for general use in California. Limited studies appear to have been carried out and any relationships developed are based on very small samples that have significant...

This summary report incorporates into a single document the design, construction, and performance data for the I-710 Freeway Rehabilitation Project in Long Beach, California. Included are the following: summaries of the asphalt mix and structural pavement section designs; construction sequence...

This report is the sixth in a series of first-level analysis reports that describe the results of HVS testing on a fullscale experiment being performed at the Richmond Field Station (RFS) to validate Caltrans overlay strategies for the rehabilitation of cracked asphalt concrete. It describes the...

Caltrans is in the process of implementing Mechanistic-Empirical design procedures. All mechanisticempirical methods must be validated/calibrated against the behavior of real pavements. This should be done before implementing models in design methods to ensure that designs will be reasonable....
