During the past few decades, the engineering and geotechnical properties of recycled concrete aggregate (RCA) has been investigated to evaluate its potential to use as a road construction material. This research studied the usage of polyvinyl alcohol (PVA) and cement for improving the mechanical strengths of RCA to be used as an alternative ...

The relational model between recycled aggregate replacement and un-confined compressive strength were established. The results of dry shrinkage tests showed that the ratio of dry shrinkage of the base materials prepared with recycled concrete aggregates increased with the increase of replacement levels of recycled concrete …

Raw materials and mix proportions. In this study, the experimental work was designed for semi-rigid base cement-stabilized macadam. The effect of different surface roughness and geometry of plastic coarse aggregate on strength properties of cement-stabilized macadam was investigated by adding plastic particles as coarse aggregate to replace …
