• Abstract:
  Like most other highway agencies in today’s economy, the Indiana Department of Transportation (INDOT) needs to search for ways to reduce construction costs. One approach to this issue is to maximize the use of locally available materials, specifically local aggregates. INDOT specifications already allow widespread use of local aggregates in deeper courses of hot mix asphalt (HMA) pavements, but surface mixes (especially for high volume traffic) typically require high friction aggregates such as steel slag, blast furnace slag or sandstone for safety. These types of aggregates are not readily available in all parts of the state, requiring long haul distances from limited sources in Indiana or even out of state. These premium aggregates are more expensive plus have the additional cost of transportation.
