Effect of angle of repose of aggregates on asphalt indirect tensile strength value

Aggregates are the major constituent of asphalt mix and the properties of the aggregates significantly affect the response of the asphalt mix. In the present study, the effect of angle of repose on the strength of asphalt mix was investigated using indirect tensile strength as a measure of the strength of the asphalt mix. Statistical relationships have been proposed between the overall angle of repose of the aggregates to the indirect tensile strength of the mix. As the measurement of angle of repose is a simple and quick test, it can be used as an indicator of the mix strength. This may be helpful in the preliminary mix design stage for selecting some mixes for further study, out of a large number of aggregate mix combinations that may be possible.
