Abstract
The effect of using manufacture waste asphalt shingles (WMAS) to mineral-asphalt mixtures besides their utilization is to reduce the amount of the new bituminous binder added to hot mix asphalt. This publication presents studies on asphalt mixtures with an increased up to 4% amount of WMAS additive with the simultaneous use of 2 types of added paving bitumen, i.e. 50/70 and 70/100. The aim of the paper is evaluation of the basic mixture properties in a wide range of operating temperatures, as a part of the HMA testing at high temperatures, the resistance to rutting at 60° C and indirect tensile strength at 40° C. The assessment of properties at intermediate operating temperatures is based on indirect tensile tests, including: elastic stiffness modulus at 5° C, 15° C and 30° C, static strength at 25° C and fatigue strength at 20° C. The low temperature properties have been tested in water and frost resistance tests by indirect tensile strength ratio and low temperature crack resistance. The results of the study were subjected to the analysis of the statistical significance of differences, which showed an improvement in the resistance of MMA with the addition of RAS to the formation of permanent deformations and an increase in the stiffness modulus as well as indirect tensile strength. There was no adverse effect of the RAS additive on HMA resistance to low-temperature cracking as well as water and frost action.
