Analysis of Cracking in Jointed Plain Concrete Pavements

Lundi, 13 Mars, 2017 - 20:45

This paper investigates the trends of longitudinal and transverse cracking in jointed concrete pavements based on Long-Term Pavement Performance (LTPP) Program Strategic Study of Structural Factors for Rigid Pavements (SPS-2) data. The impacts of slab properties, base type, traffic volume, and environmental factors on the occurrence and extent of longitudinal and transverse cracking were identified from a simple analysis of the raw cracking data. SPS-2 sites in Arizona and Arkansas were chosen to investigate cracking mechanisms in detail. A new hypothesis for the prevalence of premature cracking on these sites was proposed and tested by numerical simulations.  The full report is available from the FHWA at https://www.fhwa.dot.gov/publications/research/infrastructure/pavements/ltpp/16073/16073.pdf
