EFFECT OF USING DEMOLISHED CONCRETE AGGREGATE IN PLACE OF CONVENTIONAL AGGREGATE FOR PATCH WORK
Journal Title: International Journal of Civil Engineering and Technology - Year 2019, Vol 10, Issue 3
Abstract
Deterioration of patches is a critical problem as the patches deteriorate after some time because there is not proper bonding between existing bituminous of road and patch placed over there. In this Research paper, initially, we analyzed the strength of demolished aggregate and conventional aggregate individually. After that different combination of a binder such as lime and cement mixed with waste demolished aggregates whereas bitumen is mixed with conventional aggregate is examined. The aim of this Research is to examine the feasibility of construction demolished waste for improving the performance of patches. The main contribution of this research is to utilize construction demolished waste. The research is conducted in two phases: (i) experimental work and (ii) visual inspection. The standard tests such as Aggregate Impact value Test, Crushing value test, Specific Gravity test, Water Absorption test, and Los Angeles Abrasion test, flow value test and Marshall Apparatus test are performed. The visual inspection is performed by on foot. The results are compared by attaining values such as using bituminous patches, lime patches and concrete patches. From the experiment, it is determined that the concrete patches are stronger compared to bituminous patches and the life span of concrete patches is more than bituminous patches.
