Quick Test for Percent of Deleterious Material
Matching Research Agency
MoDOT/ Civil, Architectural, and Environmental Engineering department
|Graduate student to perform tests and analysis.|
It is proposed that a relationship be established between MoDOT’s Deleterious Materials Test (TM 71) and various quickly-determined objective tests which would cover the various controlling behavior factors that the deleterious materials method represents.
MoDOT has expressed interest in replacing its deleterious materials test method (TM 071) with something more objective. In response to an RFP issued by MoDOT, it is proposed to develop a system of standard tests which would replace the deleterious test. The system would be comprised of one or more aggregate tests, depending on the outcome of the testing.
The value of such a system of tests would be to progress toward a more objective method. Additionally, the certification of out-of-state personnel would become easier if MoDOT was using standard AASHTO tests rather than its own test method. Additionally, the work will help attain the following MoDOT tangible results: 1) Smooth and Unrestricted Roads & Bridges and 2) Best Value for Every Dollar Spent. Also, the results will provide MST with a knowledge base of aggregate durability data and testing skills.
