HOT-IN-PLACE PAVEMENT RECYCLING

Hot-In-Place Recycling (HIR) is an in-place method for rehabilitating cracked, oxidized and deteriorated pavements. HIR is a pavement recycling option that reuses existing pavement materials and provides a more cost-effective option to agencies compared to conventional milling and paving.

Road Science’s Restore^® and Encore^® hot-in-place recycling technologies involve heating and milling the existing pavement to a depth of typically 1.5-2.5 inches and adding a specialized asphalt emulsion to the millings. The mixed material is windrowed, picked up with a conventional elevator and then put into a mix paver. The material goes through the paver and screed, followed by compaction with conventional rollers. Since both processes are continuous, the end product is uniform and smooth. The end result is 100% recycled pavement material and is usually capped with a thin surface treatment.

Restore and Encore deliver typical cost savings of 30-40% compared to traditional paving methods with significant reductions in user delays.
