摘要:
A novel road-bridge link slab utilizing rubberized engineered cementitious composites (R-ECC) has been proposed for fully jointless bridges (FJBs). Preliminary research has shown that R-ECC road-bridge link slabs possess superior deformation absorption capacity, tensile strength, and crack control capabilities. However, micro-cracks developed on the surface of these slabs due to seasonal temperature fluctuations. While R-ECCs demonstrate improved bending ability compared to conventional ECCs, they exhibit lower compressive strength. Further research is necessary to investigate the crack develo...
