| Abstract: | In order to assure low temperature anti-crack performance of diatomite modified asphalt mixture, a series of laboratory tests of the asphalt mixtures that modified by three types of diatomite are studied,including low temperature bend test, direct tension test, creep test and stress relaxation test. The results show that asphalt modified by diatomite can improve the performance of asphalt at low temperature and worth being recommended to use. |
