Title: The influence of the filler-asphalt ratio on the high-and-low-temperature performance of gussasphalt mortar
Abstract: Asphalt mortar is an important component of gussasphalt mixture,a mixture of asphalt and mineral filler.Five filler-asphalt ratios are used.The high and low temperature performance changes of gussasphalt mortars with different filler-asphalt ratios are investigated using an asphalt mortar test.The results show that the higher filler-asphalt ratio could improve the high-temperature stability of gussasphalt mortar remarkably,while the lower filler-asphalt ratio could improve its low-temperature anti-cracking performance.A suitable filler-asphalt ratio therefore could balance the high-and low-temperature performance of gussasphalt mortar.It is concluded that the interaction mode between asphalt and mineral filler varies with the filler-asphalt ratio of gussasphalt mortar.
