PROJECT TITLE: New England Transportation Consortium Research Study 06-1: New England Verification of NCHRP 1-37A Mechanistic-Empirical Pavement Design Guide with Level 2 & 3 Inputs

PRINCIPAL INVESTIGATOR(S): Jo Sias Daniel, PI, University of New Hampshire and Ghassan R. Chehab, Co-PI, Pennsylvania State University

PI E-Mail: jo.daniel@unh.edu

STATUS: Active-FHWA

ANTICIPATED COMPLETION: 9/30/2011

PROJECT OBJECTIVES: Specifically, the objectives of this research project are as follows:

• Determine the design and data collection methods, material tests, and testing equipment currently in use by each state.
• Identify the Level 2 and Level 3 design guide inputs for which regional or local values are required.
• Provide state specific recommendations on implementation of the MEPDG including changes in data collection & measurement, equipment needs, training, and anticipated benefits.
• Provide specific recommendations for regional and local calibration of the MEPDG by identifying appropriate field test & monitoring sites, data to be collected, and perform local calibrations if appropriate field data is available.

PROJECT TITLE: Preventive Maintenance and Timing of Applications

PRINCIPAL INVESTIGATOR(S): Walaa S. Mogawer, PI, University of Massachusetts Dartmouth and Jo Sias Daniel, Co-Pi, University of New Hampshire

PI E-Mail: wmogawer@umassd.edu

STATUS: Scope of Work to be reviewed and revised, as necessary.

ANTICIPATED COMPLETION: To be determined

PROJECT OBJECTIVES: The purpose of this project is to understand pavement maintenance techniques and the interrelationship with the timing of their application in New England. In order to accomplish this, the following objectives have been established:

1. Identify the components of a Pavement Preventive Maintenance (PPM) program.
2. Evaluate the state-of-the-practice relative to agencies (both US and worldwide) that have demonstrated successful implementation of a pavement preservation program. Identify both single treatment and multi-treatment strategies.
3. Use current and past projects as appropriate to evaluate techniques that have been successfully used to effectively extend the life of the pavement.
4. Identify and quantify the factors that influenced the successful implementation of a preservation technique, including time of treatment application in the existing pavement life cycle.
5. Validate the treatment parameters and methodologies using Accelerated Pavement Testing (APT).
6. Determine the approximate cost for pavement preservation technique identified.
7. Develop an implementation pavement preservation manual for distribution to the state and local transportation agencies within the New England states.
