| Abstract: | Aiming at the cracking problem of cement-stabilized macadam base materials of highgrade highway,it puts forward the idea that adding SBR emulsion into the cement-stabilized macadam in order to improve its physical and mechanical properties,especially the crack resistance.By observing the microstructure of SBR emulsion modified cement-stabilized macadam by ESEM,it is expounded the mechanism that SBR emulsion improves the performances of cement-stabilized macadam.It has a certain theoretical significance and engineering value. |
