| Abstract: | Using three materials machine-made sand,stone chip which are commonly used in Hulunbeier area to do the asphalt mixture coefficient of linear contraction tests and low temperature bending test,the result shows that: The low temperature performance of asphalt mixture which use machine-made sand is greater than the one which use stone chip;The low temperature performance of asphalt mixture which use lime stone fine aggregate is greater than the ones which use andesite and diabase fine aggregate. |
