This thesis explores asphalt perpetual pavement concepts by investigating existing asphalt concrete (AC) pavements in Ohio. In 2010, twenty AC pavement sites were selected as candidates for a forensic investigation in Ohio. Field distress surveys, coring, Falling Weight Deflectometer (FWD), Seismic Property Analyzer (SPA), and the Dynamic Cone Pentrometer (DCP) tests were performed; in addition, Indirect Tensile Strength (IDT) and Resilient Modulus (E) tests were performed in the laboratory. In 2012, five of those sites were selected to perform and verify the test results. The results were similar which validated the data from 2010. FWD back-calculation was used as the basis of determining the condition of the AC base layer. The data were used to calculate layer moduli by way of back-calculation from the Evercalc 5.0 program as well as tensile strain at the bottom of the AC base layer. Layer moduli and strain values were based on 9000 pound load applied to the pavement. A conservative value of 70 micro-strains was selected as the limit for perpetual asphalt pavement classification. Seven sites were classified as perpetual pavement. One site could be modified with the addition of a surface layer mix to meet perpetual standards. Two sites were classified as damaged. This study shows that field and laboratory testing can be used to classify asphalt pavement as perpetual. FWD and SPA testing were successful in correlating pavement performance. It also highlights particular features in AC pavement structures that correlate well with excellent pavement performance such as the influence of high quality base material like asphalt-treated base (ATB). The findings proved to be useful in understanding perpetual pavement through testing of existing pavement systems.
