Using recycled concrete aggregate (RCA) as base/subbase for road construction is alternative way to manage construction waste and reduces the need for virgin aggregates. This paper discusses the long-term performance of concrete pavements on RCA granular layer in comparison to concrete pavements on virgin aggregate granular layer. 18 representative RCA pavement sections across Iowa were primary...

This data presented herein are the research summary of "mechanical behavior and durability performance of concrete containing recycled concrete aggregate" (Paul, 2011) [1]. The results reported in this article relate to an important parameter of optimum content of recycle concrete aggregate (RCA) in production of new concrete for both structural and non-structural applications. For the purpose ...

re area. In order to reduce the usage 99), Stone says that the 10mm recycled aggregate and blended stated that the use of recycled aggregate for the construction and rehabilitation of local government roads has a great improve in the last five years. C & D Recycling Industry (n.d.), the fact file stated that from the time of the Romans, the stones from the previous roads were reused when rebuil...

Rapid increase in construction activities leads to active shortage of conventional construction materials due to various regions. Concrete is most widely used construction material. Cement, sand & granite stone are the constituents of the concrete. Researches were researching for cheaper materials that can be used as substitute for these materials. In this context an experimental study was carr...

Due to urbanisation, there are large amounts of waste concrete, particularly in rapidly industrialising countries. Currently, demolished concrete is mainly recycled as aggregate for reconstruction. This study has shown that larger sizes (2-5 mm) of recycled concrete aggregate (RCA) removed more than 90% of P from effluent when at pH 5. Analysis of the data, using equilibrium models, indicated a...
