Abstract:
In order to solve the problem of long curing time and long construction time of the project，using method of hightemperature curing to shorten the curing period of macadam stabilized by limeflyash and cement. This paper adopts tests and SEM to analyze the microstructure of samples cured by hightemperature curing and standard curing, and gets the strength growing relationship between the two curing methods. Then, the author determines the strength of standard curing in 180 days from hightemperature curing strength. The result shows that the curing age of limeflyashcement stabilized macadam can be shorten, which is only about 25 days, microstructure of it can be improved, the early strength can be increased, the design parameters and major control index of ratio design for construction and can be confirmed rapidly. 9 tabs, 4 figs, 15 refs.
