Laboratorial Study on Deflection Forecasting Control Method for Controlling Construction Quality of Semi-Rigid Bases

On the basis of measuring the deflection of cement and lime stabilized gravel bases in different ages and laboratorial study, this paper analyses the surface deflection of cement and lime stabilized gravel base and the change regulations of modulus following the ages, and draws some important conclusions and presents corresponding regression formulas. According to the conclusions, a deflection forecasting control method for controlling construction quality of semi rigid bases is presented.
