The AASHTO 2002 Design Guide (2002DG) has been calibrated using Long Term Pavement Performance (LTPP) sections scattered throughout the nation but with very few sections from the state of California. This created the need to validate the models in 2002DG and recalibrate them if needed so that...

This technical memorandum summarizes the analysis performed in evaluating Long-Life Pavement Rehabilitation Strategies (LLPRS) cost. This study is part of the effort to develop an Integrated Pavement Strategy Decision Support System to allow engineers to analyze efficient allocation of financial...

This report contains a summary of the laboratory fatigue tests on mixes used as overlays on the Reflective Cracking Study Test Track at the Richmond Field Station. Evaluation of the results of the laboratory study on fatigue response of the overlay mixes reported herein included the effects of...

The conclusions from the backcalculation analysis are as follows: The overall stiffness values of the two pavement structures indicated by the surface moduli are similar. The variation along the section is typical of that of other projects in which the pavement structure is relatively...

This report focuses on the HVS testing of a foamed asphalt treated, reclaimed asphalt pavement (RAP) on State Route 89 near Sierraville. The report discusses the expected behavior of the HVS test sections, presents the results from field surveys done during June 2003, October 2003 and May 2004...

The objective of this study was to perform a laboratory investigation of the corrosion performance of several types of steel dowels embedded in concrete beams. The concrete beams and dowels were subjected to exposure to concentrated chloride solutions intended to accelerate corrosion and...

Overweight trucks traveling illegally on the California highway network cause a significant and disproportionate amount of damage to pavements. Truck traffic is expected to account for some percentage of damage to pavements, however the percentage of pavement damage caused by overweight trucks...

This report presents the results of a two-part study that compared the lifecycle costs of two long-life pavement (LLP) rehabilitation options and several conventional rehabilitation strategies for existing asphalt and concrete pavements, considering both agency costs and road user cost...

The central purpose of this research is to support the Caltrans Quiet Pavement Pilot Program. The research conforms with FHWA guidance provided to State DOTs that conduct tire/pavement noise research. The broader purpose of this research is to support the Caltrans Quieter Pavements Road Map and...

This report contains a summary of the laboratory repeated load shear tests on mixes used as overlays on the Reflective Cracking Study Test Track at the Richmond Field Station. Evaluation of the results of the laboratory study on shear response of the overlay mixes reported herein included the...
