Recycling asphalt

TRL, in collaboration with Lafarge Aggregates, Scott Wilson and Shell Bitumen, investigated the feasiblity of recycling reclaimed aggregates from worn-out asphalt surfaces as new thin asphalt surfacing materials. The recycled material performed well in tests, but was slightly inferior in several respects to the original material. A pilot test, and two road trials using 10 Economics and Administration-30% reclaimed-aggregate surfacing took place during 2004. Two contracts were fulfilled during 2006 using 23% and 25% reclaimed-aggregate surfacing for major maintenance and surface replacement on British motorways. The trials showed that it is feasible to recycle thin asphalt into new thin surfaces with up to 30% recycled content, depending on the capabilities of the plant. In increasing the proporation of recycled material, the amounts of residual binder must be carefully monitored.
