TL;DR: In this paper, the effect of mixing temperatures of HMABs using a newly proposed method for evaluating coating using coarse aggregate water absorption was evaluated. And the results showed that HMAB had higher stiffness and elasticity than neat binder.
Abstract: High modulus asphalt binders (HMABs) have been widely studied in the last 10 years. One of the most significant advantages of HMABs is their rutting resistance. In this study other factors related to the performance of HMABs in pavement engineering were studied: stiffness, elastic recovery, asphalt layer thickness reduction, workability and thermal cracking resistance. One neat binder, one hard-grade paving asphalt binder, three high modulus modifiers, and linear styrene-butadiene-styrene were included. Rotational viscosity, frequency sweep, elastic recovery and bending beam rheometer tests were performed. MEPDG software (Mechanistic-Empirical Pavement Design Guide) was selected to analyze whether HMABs could reduce the thickness of wearing or binder course. Workability was evaluated by measuring the effect of mixing temperatures of HMABs using a newly proposed method for evaluating coating using coarse aggregate water absorption. Results showed that HMABs had higher stiffness and elasticity than neat binder (Performance Grade 64-22). Based on MEPDG analysis for the same total pavement permanent deformation, it was estimated that the asphalt layer thickness was reduced by 8.9 to 27.9% by replacing the neat binder with HMABs in the study. Pavements constructed with HMABs had slightly less bottom up cracking than pavements constructed with neat binders. The coarse aggregate absorption method provided evidence that acceptable coating could be achieved at reasonable mixing temperatures for HMABs. A drawback of HMABs was the slight decrease in the low temperature performance grade. The application of HMABs where the low design temperature of the pavement is lower than -16 °C should be with caution.
