Abstract [en]

The road construction phase is one of the source of emissions (greenhouse gases), which causes climatic changes. To decrease this emission and energy consumption, asphalt industry is getting more aware of the warm mix asphalt (WMA) technology as it reduces the mixing and compaction temperature. There are several types of additives generally used for producing WMA such as: Fischer-Tropsch (FT) paraffin, Asphaltan B, Aspha-min, Evotherm etc. Fatigue and rutting resistance of asphalt mixtures could be increased by using WMA mixtures. On the other hand, the behavior of WMA mixtures in low temperature cracking is not completely clear yet. The main objective of this paper is to study the effect of commercial wax on low temperature cracking with the help of fracture mechanics.

In this study, bitumen was modified with 4% Asphaltan B as a WMA additive. Bitumen properties were determined by conventional test methods, dynamic mechanical analysis and bending beam rheometer test whereas the mixture properties investigated by Superpave InDirect Tensile (IDT) test device and Thermal Stress Restrained Specimen Test (TSRST). The similar results were obtained from both Superpave IDT and TSRST. According to the test results, the addition of wax shows a minor negative effect. This minor difference between modified and unmodified mixture is very small, so it could be within the test repeatability limit.
