Title: Influence of Asphalt Mortar on Hot Mix Asphalt Performance at High and Low Temperature
Abstract: The mortar is one important phase of asphalt mixture in accordance with mortar theory,the effect of ratio of filler/asphalt(F/A) and the effect of fiber on the property of hot mix asphalt(HMA) are studied.The test results show that the asphalt content and filler dosage have effect on the properties of HMA,the relative ratio of the two component of asphalt mortar-filler/asphalt ratio play a more important role,which affect the performance of HMA more greatly.It is recommended that the F/A ratio should be controlled strictly during the mix composition design and asphalt pavement construction.The investigation indicates that,by reducing the ratio of F/A and incorporating of some quantity of fiber into HMA instead,the flexibility and stress relaxation of HMA at low temperature can be improved,while the high temperature performance is kept or better.6 tabs,3 figs,7 refs.
