Abstract: On the basis of the principle for the highest filling degree of cement hydrates, it is synthetically considered that a matching connection between hydration of cement, volume increment of solid phase and packing density of cement paste, a calculation method for a connection between cement continuous particle size distribution and strength of cement paste is developed and tested by experiment. Based on above-mentioned analysis, a tentative research on the effect of particle size distribution of cement on strength is carried out.

Abstract: The article derived the formula of continuous particle size of asphalt aggregate packing density based on the Stovall model; according to the relationship between porosity and rutting, rutting prediction model was established; by experiment to determine the parameters in the formula to be determined , and the applicability of the formula was verified, the results showed that: the formula can calculate air voids and dynamic stability of asphalt mixture by aggregate size distribution and the aggregate ratio .
