Abstract

For Semi-rigid materials built in different season with notable different performances, the strength under different temperature of cement gravel, cement and fly ash gravel, lime and fly ash gravel are measured. The concept of temperature-integral used to judge seasonal influence on the performance of semi-rigid material is put forward, based on the connection of the ratio of temperature-integral to strength-increase ratio, recommending the strength control index for the three kinds of materials.
