Research on Performance of the Modified Asphalt by Diatomite-Cellulose Composite
The diatomite-cellulose composite (DCC) was used to modified asphalt for pavement in the study, and then the high temperature performance, low temperature performance and temperature susceptibility of asphalt were studied. The results showed that these performances of asphalt were all improved after modified by DCC, and the performance of modified asphalt significantly associated with the ash content of DCC, and H-3 DCC was the best. The performance of modified asphalt by DCC was obviously better than using diatomite and cellulose directly. The improving properties of modified asphalt by DCC were caused by synergistic effect of diatomite and cellulose.
