Abstract:

Texas Department of Transportation (TxDOT) maintenance personnel have noted problems with a commonly used, stockpiled maintenance mix known as Item 334, Hot-Mix Cold-Laid Asphalt Concrete Paving Mixture (HMCL). It is generally used by maintenance personnel as a blade-on/level-up material and as a pothole repair material. Performance problems include stripping in the stockpile, a tendency towards instability in hot weather, and a lack of winter workability. The objective of this research project was to identify a series of simple but meaningful laboratory tests and acceptance criteria for HMCL patching materials that will ensure reasonable stockpile life and field performance. A literature review was conducted to identify published information on patching materials with a particular emphasis on test procedures that have been developed for maintenance mixtures. A survey was performed of maintenance personnel in all of the TxDOT district offices to identify problems.
