| Abstract: | Based on the selection on the proper raw materials,this paper presents 3 kinds of aggregate gradations and decided on the ultimate aggregate gradation after a series of laboratory tests.As the bottom layer of the asphalt pavement with semi-rigid base,the moisture stability and strength performance of the mixture are significant to the pavement performance.Therefore,these were considered carefully by several tests.The rutting tester produced by Helmut Wind corporation were used to estimate the moisture stability of the mixture.We also used the index of critical curvature strain energy to estimate the lower temperature anti-cracking performance of the mixture. |
| Keywords: | asphalt mixture design moisture stability strength performance lower temperature anti-cracking performance critical curvature strain energy |
