Comparison of MB, RAC-G and DGAC Mixes Under HVS and Laboratory Testing

Abstract

(Key objectives, description of work, expected outcome)

To evaluate and compare the performance of Caltrans modified binder mixes under the HVS and in the laboratory against dense graded asphalt concrete and to evaluate the effects of construction and mix design variables on their performance. The expected outcome is a direct comparison of the performance of mixes meeting Caltrans MB specifications with mixes meeting AR-G and DGAC specifications. Following variables are investigated: air void content, temperature, frequency of loading, aging, dense versus gap-graded gradation, terminal-blend asphalt rubber versus wet-processed AR.

Expected deliverables are: Comparison of the performance of the mixes in fatigue and shear, Evaluation of the influence of binder properties on the laboratory fatigue and rutting resistance, Comparison between HVS test sections and lab results.
