Title
Clogging Potential Of Recycled Concrete In Road Drainage
Abstract
Recycled concrete aggregate (RCA) is often used as a replacement or partial replacement of virgin aggregate. Commonly RCA is used in road foundations (base course), embankments, hot-mix asphalt, or Portland cement concrete. However the use of RCA in drainage systems, such as French drains, is currently prohibited in the state for Florida. The primary concerns with using RCA as a drainage media are the fines content and the precipitation of calcium carbonate to cause a reducing in filter fabric permittivity. Not much research has been conducted as it relates to using RCA as a drainage material; this limited information inhibits its use in French drains. This paper describes the investigation of permeability of RCA as a No. 4 aggregate gradation and base course gradation. The effect of excess fines (passing the No. 200 sieve) and the precipitation potential of calcium carbonate have also been studied.
