Abstract
In this paper, the results of a series laboratory testing which have been conducted to evaluate the structural strength and permeability/porosity of various mixture designs of permeable concrete basecourse and surface materials have been discussed. In Australia, concrete demolition discharges solid waste to the region in extremely large quantities. To utilise various waste materials in concrete, both low-grade recycled aggregate and four different types of quarry aggregate were used in the research. The tests performed include unconfined compression, porosity and permeability tests. It was found that the compressive strength of low-grade recycled aggregate was much lower than quarry aggregate and the admixtures such as silica fume which could enhance the strength of cement paste binder will have no effect on low-grade recycled aggregate due to failure was dominated by aggregate itself. A mathematical model to predict the compressive strength of permeable concrete made with recycled aggregate was developed and compared with those made with quarry aggregates.
