Abstract:The objective of this project is to develop standardized pavement condition evaluation systems for Georgia’s rigid pavements, including continuously reinforced concrete pavement (CRCP) and jointed plain concrete pavement (JPCP). The research outcomes of this project include: 1) a first-ever CRCP pavement condition evaluation system (CRCPACES) that standardizes the condition survey of six distresses (including distress types, severity levels, extents, and measurement methods) using a windshield survey and a walkthrough survey and a rating system with distress deducts; 2) a tablet-based CRCPACES application to facilitate the data collection process and the implementation of CRCPACES; 3) an enhanced JPCP pavement condition evaluation system (JPCPACES) with a finer distress categorization to better monitor severe distresses in aged JPCP and refined treatment criteria based on today’s JPCP condition; 4) a tablet-based JPCPACES application with features similar to the CRCPACES application to improve the data collection process by eliminating the existing pen-and-paper recording method; 5) new modern Georgia Faultmeters that are used for annual faulting measurement operations; and 6) a 2D-based faulting measurement method that safely and effectively measures faulting using 3D pavement data. CRCPACES, JPCPACES, and the modern Georgia Faultmeters have been validated and successfully implemented. In addition, the 2D-based faulting measurement method has been recommended for future faulting measurement operations.
