Abstract:
In order to evaluate the effect of different materials on the strength of CEACRM, the mixing design experiments of CEACRM with two kinds of reclaimedasphaltpavement(RAP) mass ration were conducted. In the orthogonal tests three factors of cements mass ration, emulsified asphalts mass ration and waters mass ration were considered with three levels adopted in every factor. On the basis of variance analysis of the test results, the effect of the factors on the strength of recycled mixture was investigated. The result shows that the cements mass ration and emulsified asphalts mass ration have different effects on the strength of recycled mixture with different RAP mass ration; the emulsified asphalt has the main effect on the initial strength and anaphase strength of CEACRM when the RAP mass ration is low; the cement has the main effect on the initial strength, and the emulsified asphalt has the main effect on the anaphase strength of CEACRM when the RAP mass ratio is high; the waters mass ratio has the least effect on the strength; the optimum mass ratio of the cement is 2% when the low RAP mass ratio is low, and the optimum mass ratio of the cement should be confirmed according to the cost analysis result when the RAM mass ratio is high. 7 tabs, 2 figs, 9 refs.
