Non-invasive Imaging and Assessment of Pavements

To rapidly and cost-effectively assess the condition of new and existing pavements, various non-invasive in situ data must be collected and interpreted. The extent and level of data needed depends on the type of pavement condition information sought (distress, structural capacity, or surface characteristics) and influences the type of assessment conducted (network-level or project-level). The objective of the proposed research is to thoroughly assess, in part through network-level and project-level field studies, the non-invasive imaging technologies identified as applicable to roadways. The intent is to develop a guidance document focused on the utility and cost-effectiveness of identified project-applicable and network-applicable non-invasive imaging technologies. The guidance document will focus on when, where and how to use each tool. The optimal utilization of appropriate non-invasive technologies will result in more accurate pavement assessments and significantly reduced costs. The tools to be tested can be applied to new pavements for quality control and quality assurance purposes, and can be used to assess existing pavements. The tools to be tested will generate reliable information about thicknesses, moisture content, and elastic moduli of pavement. Information can also be generated about the thickness, elastic moduli, clay content and moisture content of the soil.
