PAVEMENT QUALITY INDICATOR FIELD OPERATIONAL TESTING AND PRODUCT TRANSFER

This Innovations Deserving Exploratory Analysis (IDEA) project is the final phase of development and testing of the Pavement Quality Indicator (PQI). This project builds upon the successful accomplishments of a prior IDEA Project, NCHRP-32. The recently completed phase of work under NCHRP-47 was divided into three distinct stages with the following objectives: Stage 1 - Design upgrades to the system for pre-production operations testing, establish the technical validity of the system in terms of electrical parameters measured and indicator levels derived for pavement quality, develop information to optimize design configuration and corrections, if any, taking into consideration site and local variations in mix designs during paving operations, construct at least 10 pre-production units ready for field trials, and convene the regional panel of experts to discuss issues on technical validity and reliability and evaluate project plans for field operational tests; Stage 2 - Perform field operational tests in at least 6 job sites, analyze data and review results, revise product design and specifications to meet commercial standards, and convene a regional panel of experts to discuss findings and strategies for marketing; and Stage 3 - Develop and implement strategies for transfer of the PQI system to pavement practice, and develop and implement plans for establishing manufacturing sources. Key results of this phase of the project, challenges which were encountered and met, and final conclusions are detailed in this report.
