Instrumentation for Mechanistic Design Implementation
Principal Investigator:
Todd Scholz, Oregon State University
Summary:
The principal objective of the research project was to obtain key information (i.e., engineering properties of the materials used for construction and in-service response of these materials to applied truck loads) to be used to assess the validity of predicted tensile strain via layered elastic analysis. More specifically, the objectives of the project were to: 1. Instrument three new HMA pavement...
The principal objective of the research project was to obtain key information (i.e., engineering properties of the materials used for construction and in-service response of these materials to applied truck loads) to be used to assess the validity of predicted tensile strain via layered elastic analysis. More specifically, the objectives of the project were to: 1. Instrument three new HMA pavements with differing structure and truck traffic volume, and constructed in differing climatic conditions such that pavement response due to truck loading could be measured periodically throughout the year. 2. Conduct necessary field testing and obtain field samples for laboratory testing. 3. Conduct the necessary laboratory tests on the samples obtained from the test sites. 4. Collect data from the instrumented test sites. 5. Use the data collected from the instrumented pavements (i.e., axle loads, axle configurations and/or truck classification, induced tensile strain, and pavement temperature) as well as information derived from laboratory tests conducted on the field samples to validate tensile strain prediction via layered elastic analysis for the range of pavement structures, truck traffic volumes, and climatic conditions investigated.
