Abstract
Reclaimed asphalt pavement (RAP) has been used in pavement rehabilitation and reconstruction for decades. Positive and sustainable benefits (cost, environmental and societal) of increased RAP usage have been documented by the National Asphalt Pavement Association (NAPA). Nebraska Department of Transportation (DOT) has recently reported annual savings of $60 million by using RAP. National and State studies have compared performance of asphalt mixtures with and without RAP. When properly engineered, produced, and constructed, high RAP asphalt mixtures can provide comparable levels of service as asphalt mixtures with no reclaimed materials
