| Abstract: | Through experimental research of basic mechanical properties,comparative study of the strength properties of semi-rigid base materials including lime-flyash-cement stabilized macadam was carried out.Through study of the indices of water loss rate,dry shrinkage strain and shrinkage coefficient,dry shrinkage performance of lime-flyash-cement stabilized macadam and other semi-rigid base materials was analyzed.By regression analysis,the relation of accumulative dry shrinkage amount with time and accumulative wa... |
