| Abstract: | Considering that there is no terms about the test method and requirement of the effective relative density of aggregate in Chinese current specifications of aggregate,a theoretical and test study of the effective relative density of aggregate is carried out in the paper. The test method and principles are described,and the test characteristics and matters to which attention should be paid are discussed. This study is beneficial to the determination of the volume parameters in the design of bituminous mixtures and to the improvement of the current test methods of bitumen and bituminous mixtures. |
