Hot Bituminous Pavement Recycling US-56, Edwards and Pawnee Counties, Kansas

摘要

A study was undertaken between 1978 and 1993 to construct and monitor a hotrecycle section. One hot recycle test section and one control section were completed in 1978 and monitored for cracking for approximately 12 years. This project was the first hot recycle project constructed in Kansas and one of the first in the United States. Using the experimental cost data and only cracking to determine pavement life, this hot recycle project was not economically feasible. Wheelpath rutting was not a problem throughout the life of both pavements. Opacity and particulate requirements were never met on this first hot recycle project. Due to the many unknowns, the project was considered a success.
