Abstract:

Current test procedures in TxDOT specification Item 300, “Asphalts, Oils, and Emulsions” were reviewed for relevance, applicability, accuracy, and practicality, and recommendations were made for improving the tests and specifications. New test procedures were developed, as identified, to fulfill needed changes. Data for new proposed test procedures was generated and analyzed to develop suggested specification limits. This data explored the agreement between laboratories, developed test conditions, and facilitated round-robin experiments. Suggested changes were made for each table of the material specifications. A new long-term aging test was developed for PG binders.
