| Abstract: | This report documents the findings from the research that was carried out as part of Phase II of Texas Department of Transportation (TxDOT) Project 0-5627. The research included measuring and analyzing the mechanical and physical properties of aggregates used in surface mixes in the state of Texas. These properties were aggregate shape characteristics measured by the Aggregate Imaging System (AIMS), British pendulum value, coarse-aggregate acid insolubility, Los Angeles weight loss, Micro-Deval weight loss, and magnesium-sulfate weight loss. In addition, a database of field skid-number measurements that were obtained over a number of years using the skid trailer was established. Field measurements of selected sections were conducted using the dynamic friction tester (DFT) and circular texture meter (CTMeter).These data and measurements were used to carry out comprehensive statistical analyses of the influence of aggregate properties and mixture design on the skid-resistance value and its variability. Consequently, a system was developed for predicting asphalt-pavement skid resistance based on aggregate characteristics and aggregate gradation. |
