- Abstract:
- The gradation segregation of asphalt mixture is one of the causes of early damage of asphalt pave.ment ; the large size asphalt mixtures have more prone to aggregate segregalion due to the coarse aggregate con-tent more than the normal asphalt mixes. This paper developed the measuring instrument of the aggregate segregation of asphalt mix. The different types of asphalt mives with five gradations had done the gradation segre.gation test, its reliability was verified. The test results show that large size asphalt mixture using Bailey methoddesign had the strong resistanee to segregation characteristies than AC type asphal mixture ; the aggregate passrate differenee between belore and after stockbin was suggested to evaluation asphalt mixture gradation segregaton.
