POST-CAST HEADERS FOR ASPHALT CONCRETE SURFACING AT EXPANSION JOINTS OF HIGHWAY STRUCTURES
This report discusses the possible causes of problems with post-cast headers installed by contractors on California State Highway projects. The study consisted of an examination and evaluation of 178 headers constructed of various materials: epoxy-concrete, portland cement concrete, steel angles, urethane and several proprietary products. Portland cement concrete headers were found to perform reasonably well, but require additional set time before traffic loads can be applied. High alumina cement concrete, polymer concrete, and high strength quick setting concrete show promise but have not been used in headers to date. Special header problems associated with snow areas are discussed.
