A guide to evaluating thermal effects in concrete pavements / by Andersen, Per Just.; Whiting, D.(David)(CARDINAL)317085; Strategic Highway Research Program (U.S.)(CARDINAL)298325;
Includes bibliographical references (pages 41-42).Introduction -- Theoretical background -- Calculation and evaluation of thermal effects -- Input parameters -- Users' guide -- References -- Appendix: Thermal effects tables.This report describes the use of tables developed to help determine problems that may result from early thermal effects in concrete. The thermal behavior of concrete can be estimated from a knowledge of concrete temperature, air temperature, type of cement, and content of cement in the mixture. The thermal effects tables can be used to predict whether too high a temperature will be reached in the pavement; whether early thermal cracking will result from larger differences between the temperature of the concrete slab and the temperature of either the air or the base; or whether there is a risk of early cracking of the concrete. Examples of the use of the table are given along with guidelines for avoiding undesirable thermal effects.Performed under contract no.

Optimization of highway concrete technology / by Whiting, D.(David)(CARDINAL)317085; Strategic Highway Research Program (U.S.)(CARDINAL)298325;
Includes bibliographical references (pages 135-140).Executive summary -- Introduction -- State-of-the art concrete highway technology -- Development of test methods for fresh concrete -- Field studies of new test procedures, materials, and criteria for concrete rehabilitation -- Highway concrete expert system -- Implementation packages for highway personnel -- Conclusions and recommendations -- References -- Appendices.This 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.Performed under contract no.

Investigation of a pavement crack-filling robot / by Carnegie Mellon University.Department of Civil Engineering.(CARDINAL)325473; Strategic Highway Research Program (U.S.)(CARDINAL)298325;
Performed under contract no.Includes bibliographical references (pages 103-109).Executive summary -- Introduction -- Sensing pavement cracks -- Representing pavement cracks -- Filling pavement cracks -- Alternative system designs -- Economic analysis -- Introduction -- System architecture -- Sensing hardware -- Representation -- Software implementation for perception and control -- Test scene perception and processing -- Second generation design and field demonstration -- Evaluation of automated crack filling -- Appendixes -- References.This report describes a laboratory prototype designed to identify, map, track, and fill pavement cracks. Video imaging and electronic scanning equipment installed in a van is followed by a rack carrying a hot-air lance, a sealant wand, and a supply trailer. The video sensor identifies potential cracks while the depth sensor verifies actual depth. A map plotter defines the crack length, size, and depth. Using the combination of visual and depth sensing equipment, the cracks located and mapped were filled with an accuracy of better than 1 cm (0.5 in). Approximately 125 million dollars per year is spent by states on crack-filling with labor representing 50 percent of the costs. Assuming a 4-year system life at a cost of 100,000 dollars plus annual maintenance and operating costs of 25,000 dollars per year, potential savings could be as much as 60,000 dollars per unit, per year or 19 percent of costs on a national basis equal to 24 million dollars per year.
