Application analysis of high-performance concrete on heavy traffic cement concrete pavement

Thorough a further analysis and research on Engineering advantages of high performance concrete, determine the amount of cement, superplasticizer admixture and fatigue properties, the paper draw a method of determining of the amount of cement and superplasticizer dosage and the specific method for determining the magnitude standards, proposed the equation that shows the relationship between fatigue life when the probability of failure reach to 50% and stress level. Based that, though a comparative analysis on economic benefits between high performance concrete pavement and ordinary concrete pavement, that the conditions allow, the use of high performance concrete materials, not only can significantly improve the flexural strength of concrete panels and service life, simultaneously thinning the thickness of the surface layer will not substantially increase the cost of the road.
