Chapter Fiveprocessing one of the keys to recovering old pcc for use as rca is in the initial processing that involved: ⢠removal of as many potential contaminates before demo lition of pcc as possible ⢠demolition of pcc structure ⢠crushing and sizing rca ⢠secondary removal of contaminates ⢠removal of dust and fines ⢠washing (optional but .
PROPERTIES OF RECYCLED CONCRETE AGGREGATES FOR AIRFIELD RIGID PAVEMENTSRecycled concrete aggregate (RCA) was investigated as a partial and full replacement of coarse aggregate and partial replacement of fine aggregate in concrete for airfield pavement appliions. All mixtures explored used a total cementitious content of 517 lb/yd3and a watertocementitious ratio of In addition,
Recycling of a Concrete Pavement after over 80 Years in . · This article presents the results of fatigue testing and assessment of the mechanical and physical properties of the concrete pavement of the A6 motorway, which was put in service in 1938. After 82 years of operation under heavy traffic loading conditions, the pavement was fully recycled by crushing of the existing concrete and reuse of the reclaimed material in the new .
Chapter 1 · The Asphalt Recycling and Reclaiming Association (ARRA) has identified three HIR processes; (a) surface recycling, (b) repaving, and (c) remixing. Figure 13 shows a surface recycling operation. This is a type of HIR operation in which the existing asphalt surface is heated and scarified to a specified depth.

Performance of Rigid Pavements Containing Recycled Concrete .tions. In general, the recycled PCC pavements considered in this study have performed comparably with their conventional PCC pavement counterparts, including the recycled pavements that incorporated RCA derived from concrete affected by Dcracking and alkalisilica reactivity (ASR). There is, however, evidence of small amounts of local
Chapter 3 · A pavement recycled by cold process may need about one to three percent of asphalt binder compared to about six percent for a new asphalt concrete pavement This amounts to savings of about 10 gallons of asphalt binder per ton of the mix. (3) Cold recycling can also substantially reduce energy consumption by the pavement industry.
