PDF Evaluation of Cold In-Place Recycling for Rehabilitation

Successful rehabilitation of transverse cracked hot mix asphalt (HMA) pavements has been a challenge for state DOTs. Conventional thin HMA overlays allow the rapid return of the existing transverse cracks and thicker HMA overlays are cost prohibitive. Cold In-Place Recycling (CIR) has been shown to be a

Rutting performance prediction of warm mix asphalt

Nowadays, saving energy and recycling materials are becoming priorities in the road construction industry. This paper presents an experimental study to characterise permanent deformation of a warm mix asphalt (WMA) mixture containing reclaimed asphalt pavement (RAP). The WMA mixtures containing 0%, 15%, 30%, 50% and 60% of RAP were plant prepared.

Guayule Plant Extracts as Recycling Agents in Hot Mix

Goals / Objectives Background:Increased usage of reclaimed asphalt pavement (RAP) and reclaimed asphalt roofing shingles (RAS) in hot mix asphalt (HMA) has increased the need for recycling agents which are additives, historically petroleum-based, designed to return the age-hardened (oxidized) RAP/RAS binder (asphalt) to its original state. However, a decreasing supply of liquid asphalt
