通过对不同长度的普通水泥混凝土路面板与橡胶粉水泥混凝土路面板板中中点和板边缘中点受到的温度胀缩应力、温度翘曲应力计算和分析,得到橡胶粉水泥混凝土路面板按6m长度分缝与目前我国普通水泥混凝土路面板按4.5m长度分缝受到的温度胀缩应力、温度翘曲应力大致相等,有效的证明了橡胶粉水泥混凝土路面可以减少接缝的设置,提高混凝土路面的使用品质和耐久性等性能。经过经济性分析,在相同条件下铺筑橡胶粉水泥混凝土路面的造价略低于普通水泥混凝土路面,这为橡胶粉水泥混凝土在道路路面上的推广应用奠定了基础。
Based on different lengths of ordinary cement concrete pavement and rubber Cement Concrete Pavement Board To Board in the mid-point and the edge of the mid-point by the temperature of plate swelling and shrinkage stress,the temperature warping stress calculation and analysis,to be rubber Cement Concrete Pavement 6 m length by parting with the present,China's ordinary Portland cement concrete pavement by 4.5 m length of the parting by the temperature of swelling and shrinkage stress,the temperature warping stresses roughly equal and effective proof of the rubber powder can reduce the cement concrete pavement joints is set to improve The use of concrete pavement quality and durability properties.Through economic analysis,in the same conditions,paving rubber cement concrete pavement construction costs slightly less than ordinary cement concrete pavement,which for the rubber cement concrete road surface on the promotion and application of foundation.
