While at TTI, Mr. Freeman has served as Principal Investigator or been involved in a wide variety of projects for the Strategic Highway Research Plan (SHRP), Federal Highway Administration, Texas Department of Transportation and other organizations.
SHRP work included the Maintenance Effectiveness for AC and PCC Pavements (H-101) project and the Performance Models and Validation of Test Results (A-005) project. The H-101 project included a study of the effectiveness of performing thin overlays, crack sealing, slurry seals, and chip seals as preventive maintenance on AC pavements and the effect of crack sealing and undersealing on the performance of PCC pavements. This work was used in the development of the SHRP Superpave mix design system.
Recently, Mr. Freeman was Co-Principal Investigator on an FHWA project to teach train-the-trainer courses on pavement management to local agencies. The project involved development of train-the-trainer materials and a pavement management software catalog.
Mr. Freeman is also the Principal Investigator for the Texas Department of Transportation's Supplemental Maintenance Effectiveness Research Program (SMERP). This program studies the effectiveness of rubber, latex, polymer modified emulsion, conventional AC chip seals, and micro surfacing on the performance of AC pavement in Texas. This project is an extension of the H-101 project but uses Texas treatments and Texas pavements. The treatments were placed in 1993 and have been surveyed six, twelve, and twenty-four months after construction in order to establish their performance effectiveness. This is an on-going project. Treatments will be surveyed every year until failure is detected at each site.
Mr. Freeman has worked extensively in implementing the PAVER Pavement Maintenance Management System and has assisted the Corps of Engineers in the development of this system.
