Optimization of Highway Concrete Technology
The report provides (1) state-of-the-art information on new developments in portland cement concrete materials and applications to users in the highway agencies, especially young engineers just beginning their careers in the field; and (2) new materials and testing methodologies for a variety of important highway and bridge rehabilitation applications. The report includes a condensation of the state-of-the-art synthesis of concrete highway technology prepared as part of this research project. Descriptions of evaluations of test methods for in-place concrete density with the use of nuclear methods and determination of water content of fresh concrete using microwave drying are also incorporated in the report. The report gives summaries of guidelines for avoiding thermal effects in concrete pavement slab placements and packing-based aggregate proportioning for concrete mixtures. The report contains a detailed description of field evaluations of a variety of concrete mixes used for early opening of full depth concrete pavement repairs and bridge deck overlays. Opening times ranged from 2 to 24 hours. Brief descriptions of the methodology and content of the HWYCON expert system, available from SHRP, are also included. Finally, a description of the contents of audiovisual implementation packages for highway personnel dealing with materials testing and pavement and bridge rehabilitation is included.
