In the past fifty years many significant changes have occurred in the road building industry. The engineers who designed highways never envisioned the amount of traffic and weights of the trucks traveling over the road network. These factors have contributed to the rapid deterioration of many low volume roads. This combined with lower funding rates has painted a bleak picture of the highway systems in North America. The use of full depth recycling with calcium chloride has produced a cost effective method of combating the rapid deterioration of many low volume roads. Full depth recycling continues to grow; in 1994-95 there was approximately 450-500 kilometers done. The interest in full depth recycling continues to grow. This paper will focus on full depth recycling with calcium chloride and the technical data that has been amassed. This additive has produced results that prove without a doubt its versatility and effectiveness in reducing frost heaves as well as aiding in compaction. (A) For related work see IRRD 880786.
