Description:

The research objectives are to assess the PSV test variation by testing diff erent aggregate sources, shipment times, and test operators; propose a new aggregate friction testing procedure for DOTD, which can be used for initial source approval as well as for predicting field friction performance of wearing course aggregates; determine threshold friction design values for commonly-used wearing course mixtures; to validate and update the correlations obtained in prior LTRC project 12-5P: Evaluation of DOTD Aggregate Friction Rating Table by Field Measurements for different pavement friction and texture testing devices, different types of test tires (ribbed and smooth), and different testing speeds; and validate and update the relationship between Skid Number (SN) and International Friction Index (IFI) developed in prior LTRC project 09-2B: Development of Surface Friction Guidelines for DOTD through both laboratory and field testing programs.
