ترجمة الملخص

Most of studies and scientific researches have recently focused on the possibility of using recycled concrete aggregate (RCA) (resulting from recycling building demolition waste) to produce hot mix asphalt (HMA) for roads. The percentage of (RCA) in these studies varied in accordance with the case of study and standards.This research has been carried out as a try to find the highest possible ratio of (RCA) aggregates to produce hot asphalt mix, by using fine aggregate gradation (gradation 2 of wearing course) in accordance with the Syrian technical limits and specifications in 2002,for fine aggregate gradation (laboratories waste) which have the same values of cement standards and cubic resistance.At first a 60% RCA asphalt mix had been designed according to Marshall's method, and it was accepted. After that a 75% RCA asphalt mix had been studies, but voids in mineral aggregates ratio was not accepted. That's why the effect of changing Mrashall compaction energy on gradation's curve of this mix had been chosen to study.The results of this study have showed that 60%RCA can be used for heavy traffic roads, and the optimum asphalt binder was 6.3%. While 75% RCA cannot be used in any of light, medium or heavy traffic roads, because the three Marshall compaction energies (75,50,35 blows) all of them caused of going the gradation curve outside the allowable area adopted in this study.
