Marshall properties were determined on mixes from three different contractors each producing a 1/2-in and a 3/4-in top-sized aggregate mix. From these data, statistical analyses were made to determine differences among contractors and between mix types. The data were analyzed to develop tolerances that could be used in a performance related specification. A suggested specification including risk factors, OC curve, and pay factor schedule are included.
Several processes have been developed to reduce the mixing and compaction temperatures of hot mix asphalt (HMA) without sacrificing the quality of the...
The objective of this subtask was to generate crack resistant hot mix designs which could be placed very thin using locally available materials for ea...
