Pavement Recycling-Bituminous Concrete and Concrete Mix Designs
Trial mixes developed from both salvaged bituminous-concrete and portland-cement concrete pavement materials were tested in the laboratory. Salvaged materials investigated included crushed and cold-milled bituminous concrete and crushed 40 x 12-ft concrete pavement slabs with wire-mesh reinforcing. Laboratory results indicated the feasibility of full-scale bituminous recycling projects using central-plant mixing of salvaged and virgin aggregate by the heat-transfer method and both in-place full-depth and surface recycling. The concrete tests provided good results in terms of strength properties and demonstrated the potential of concrete recycling. Mesh separation and removal did not present any insurmountable problems. Experimental design and specifications for full-scale field projects are included for both recycled concrete and bituminous concrete, together with a plan for post-construction evaluation of the various recycled pavements.
