High Early Strength Bonded Concrete Overlay Designs and Construction Methods for Rehabilitation of CRCP
For rehabilitation of concrete pavements, resurfacing with a bonded concrete overlay (BCO) may provide significantly longer life and reduced maintenance costs. Two important issues are bonding and rapid reopening of resurfaced sections. The project objective was to determine a method or methods for constructing a bonded concrete overlay under extreme weather conditions in El Paso, Texas, that would ensure early opening to traffic and achieve design requirements for long-term performance, and to investigate methods of detecting and mapping delaminations nondestructively. A BCO test slab was designed and constructed for a full-scale test of feasible design and construction alternatives. The month of June was selected for the test because severe environmental conditions were expected. The experimental variables encompassed in eight test sections were reinforcement of concrete (plain, polypropylene fiber reinforced, and steel fiber reinforced), use of shear connectors (nails and anchors), reinforcement, surface preparation, and day or night construction.
