Project description

This paper describes the impact of joint spacing or panel size on the performance and relative cost of short jointed bonded concrete overlay of asphalt (SJPCP) pavement using the AASHTO Pavement ME Design procedure. Joint spacing, or panel dimension, is a critical design issue that greatly affects both performance and cost of the SJPCP as well as conventional jointed plain concrete pavement (JPCP) overlays. In fact, pavement performance is more dictated by the panel size than thickness.
