A study was undertaken between 1985 and 1992 to construct a cold inplace recycled bituminous pavement using three different asphalt additives. The three additives were ARA-1, RA-100 with kerosene, and a product known as Gas/oil. Using these products three different test sections were completed in 1985 and monitored for rutting and cracking for approximately 6 years. The project starts approximately two miles south of Gem, Kansas (secondary road in Thomas County) and extends back north for six miles. In 1988 a maintenance overlay was applied to all of the project to correct the rutting that had developed in the cold recycle sections. The project was monitored further for another three years but no major problems developed in the sections. Wheelpath rutting has not returned and the ride is still satisfactory.
