Guayule Plant Extracts as Recycling Agents in Hot Mix

Goals / Objectives Background:Increased usage of reclaimed asphalt pavement (RAP) and reclaimed asphalt roofing shingles (RAS) in hot mix asphalt (HMA) has increased the need for recycling agents which are additives, historically petroleum-based, designed to return the age-hardened (oxidized) RAP/RAS binder (asphalt) to its original state. However, a decreasing supply of liquid asphalt

Marshall Mix Design. The basic concepts of the Marshall mix design method were originally developed by Bruce Marshall of the Mississippi Highway Department around 1939 and then refined by the U.S. Army. Currently, the Marshall method is used in some capacity by about 38 states. The Marshall method seeks to select the asphalt binder content at a
