Abstract

Joints in cement concrete pavements frequently contribute to decreased ride quality, accelerated pavement deterioration, and complex maintenance procedures. To mitigate these issues, this study proposes the use of engineered cementitious composites (ECC) as connectors at pavement joints, creating a jointless cement concrete pavement (JCCP) system. A finite element model was developed to evaluate the structural performance of JCCP, taking into account variables such as vehicle loading, width and thickness of ECC connector dimensions. The mechanical behavior of the JCCP under combined loading and temperature-induced stresses was analyzed, and the critical load position was identified. The results reveal that the most critical load position occurs directly above the induced crack in the pavement. The integration of ECC connecting elements reduced the maximum tensile stress at the base of the pavement by nearly 50%. Based on these findings, it is recommended to utilize ECC connectors with a width of 30 cm, and a thickness equal to 50% of the pavement slab’s thickness.
