Investigation of Two-Inch Surface Recycle Process in Kansas on US-59 South of Nortonville

The two-inch hot surface recycle process for asphalt pavement preservation is relatively new to Kansas. The hot recycling process uses six propane heating units, three milling machines and a paving machine to achieve a two-inch total depth of recycled material. This recycled layer is then covered with a 1.0- to 1.5-inch thick overlay wearing surface. This investigation was to determine the changes in the pavement properties as the old pavement surface material is processed by the recycling operation during construction. This specific project was in Jefferson County on US-59 south of Nortonville. The before and after asphalt content and thermal cracking properties were looked at, as well as the gradation and potential rutting stability of the recycled mixture. This was not a full in-depth study, but rather, an initial preliminary review of the process.
