Several states have sponsored laboratory and field studies looking at the feasibility of using RAS in HMA pavement. States such as Georgia, Ohio, North Carolina, Minnesota and Texas have performed laboratory studies. Many other laboratory studies may be found on the Technical Reports and Articles pages. Field studies also have been conducted in which portions of highways or trailways have been paved with asphalt containing recycled shingles and have been monitored over time. Pennsylvania, North Carolina and Minnesota have conducted such trials. Benefits shown from these studies include:
Because of the benefits shown by using RAS in HMA pavement, several states allow a certain percentage of RAS to be used in HMA pavements.
