| Abstract: | From the fact of the concrete pavement construction in mountainous areas,the paper researches the mechanism of the cracks at early stage on the highway pavements in mountainous areas,and points out a feasible and factual concrete craft by adjusting the water cement ratio,the pumping agent,the sand ratio and the collapsed slump,so as to improve the crack resistance at early age of concrete pavement in mountainous highway. |
