Project detail
Roadmap/Focus area(s):   Infrastructure Research and Technology Strategic Plan and Roadmap
Project Description:   Forensic studies are a valuable tool in pavement engineering. With the development of the Mechanistic-Empirical Design Guide, the forensic study will be a valuable tool to departments of transportation so that they can verify design decisions or verify mistakes in the design or construction process. Why did the pavement rut? Inferior subgrade, bad mix, or poor construction? Only forensics will allow you to determine this. There are a number of States that conduct forensic studies and there are a number of guidelines that have been developed to assist someone conducting a forensic study. The problem is that there is no published forensic guideline documents and everyone has a different view on how to conduct a forensic study. The project would be a two- phase study. The first phase would be to conduct a National Forensic Workshop. The workshop would focus on what States and other organizations are doing in the area of forensics and would include field presentations of some forensic techniques. There would be invited speakers and funding for speakers' travel and for some States. Phase two of the project would be to develop forensic guidelines using the input from the workshop and the current existing documents on conducting forensic studies.
Goals:   Existing pavement condition assessment.
Product Type:   Research report
Training materials
Test Methodology:   Workshop
Other Information:   LTPP Analysis Plan | Objective 5 | Outcome E | Priority High | Sequence 1
Expected Benefits:   The ultimate benefit is the advancement of forensic studies and the impact on the implementation of the Mechanistic-Empirical Design Guide. The payoff from the national workshop is the sharing of ideas among pavement engineers. The payoff from phase two is the forensic guidelines for the pavement community.
Deliverables:   Forensic guidelines and national workshop.
