Bond strength of whitetoppings and bonded overlays constructed with self-compacting high-performance concrete
HighlightsDirect pouring of SCHPC provides bond strengths comparable to the other treatments.Cohesive failure is obtained in asphalt substrates without interfacial treatment.No correlation exists between roughness level, pure tension and shear strengths.
AbstractA bonded concrete overlay consists of a concrete layer poured over a deteriorated pavement. Its mechanical performance depends on the quality of the bond between the lower and the uppermost layers. This paper reports an extensive experimental program to evaluate bond strength between Conventional Concrete (CC) and Asphalt Concrete (AC) substrates and Self-Compacting High-Performance Concrete (SCHPC) overlays. In all, 8 interface treatments are tested under Direct Tension, pure shear “LCB”, and compressive Slant Shear tests. The results show that direct pouring of the SCHPC overlay over CC and AC substrates produces similar or higher strengths than the other treatments analyzed.
