Route 5 near the Florin Road overcrossing (PM 17.2/17.9) in Sacramento County is one of the eight quiet pavement test sections where traffic noise measurements are being conducted by the Caltrans Division of Environmental Analysis Team. This section is a rubberized asphalt concrete open graded...

This report presents the results of the study, "Pilot Project for Fixed Segmentation of the Pavement Network." The goal of this pilot project was to study a small sample of the California Department of Transportation (Caltrans) network to determine the feasibility of expanding the pilot approach...

This document compares the results of flexural fatigue tests performed on experimental concrete beams made of the standard Caltrans concrete mix and five other fast-setting mixes. The three research objectives were: to investigate the fatigue characteristics of the fast-setting mixes, to compare...

This report summarizes the investigations undertaken by the University of California Pavement Research center between 1998 and 2005 to assess Caltrans strategies for the construction of rigid pavements, specifically jointed plain concrete pavement. The overall objectives of the study are...

This report is one in a series that describe the results of HVS testing and associated analyses on a full-scale experiment being performed at the Richmond Field Station (RFS) to validate Caltrans overlay strategies for the rehabilitation of cracked asphalt concrete. It describes the analysis of...

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 presents the details on the construction and preliminary load tests on an experimental pavement comprised of ten pre-cast slabs of the pavement known as the Super-Slab® System, installed at the intersection of I-15 and SR210, in San Bernardino County in southern California. 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...
