Development of Longitudinal Cracking Models for Concrete Pavements

The formation of longitudinal cracks compromises the structural adequacy and reduces the service life of jointed plain concrete pavement (JPCP). Although longitudinal cracking in JPCP has been widely observed by state transportation agencies, the current version of the AASHTOWare pavement mechanistic-empirical design (PMED) software does not account for this critical distress. Studies indicate that longitudinal cracks can be caused by various factors, ranging from construction issues to specific design features. Research is needed to understand the causes of this distress pattern better and more accurately predict it to prevent or minimize longitudinal cracking, resulting in safer and longer-lasting pavements. OBJECTIVE: The objective of this project is to identify the causes of longitudinal cracking in JPCP and develop longitudinal cracking predictive models.
