• Abstract:
  Over 90% of U.S. highways and roads are constructed with hot mix asphalt (HMA) and as this ; infrastructure ages, these highways and roads must be maintained and rehabilitated. The 1970s marked ; the beginning of the widespread use of reclaimed asphalt pavement (RAP) in asphalt pavements in the ; United States. However, in early years, many state Department of Transportations (DOTs) used only a ; low percentage of RAP materials in their hot mix asphalt (HMA) mixtures. One major reason for this ; was that the mixtures containing high RAP contents could result in increased “blue smoke” emissions ; from plants since the RAP materials were fed directly into the path of hot gasses. However, with the ; modern design of new plants, this is no longer a major concern. There were three major objectives for ; this research project. The first was to analyze the cost benefits to the Department from the past ; utilization of RAP, RAS, and RAP/RAS in various mixtures around the state. The second objective was ; to develop a proposed pay schedule for aged binder versus virgin binder in the form of a draft ; specification. The third was to predict the potential cost savings to SCDOT from the use of the ; proposed alternate pay schedule. The researchers mined data from three different databases (Site ; Manager, Job-Mix-Formula (JMF) Log, and each individual JMF form per project) in order to generate ; the necessary information to complete project objectives.
