"TRB's National Cooperative Highway Research Program (NCHRP) 749: Methods for Evaluating Fly Ash for Use in Highway Concrete presents suggested changes to coal fly ash specifications and test protocols contained in American Association of State Highway and Transportation Officials (AASHTO) Standard Specifications for Transportation Materials and Methods of Sampling and Testing (AASHTO M 295). The changes suggested include modifications to the test methods currently specified for evaluating acceptability of fly ash for use in highway concrete as well as the introduction of new test methods for enhancing such evaluations. Attachment C: Details of the Research into Methods for Evaluating Fly Ash Use in Highway Concrete is only available online."--Publisher description.

"This report presents a recommended procedure for evaluating air-entraining admixtures used in highway concrete. The procedure involves the testing of non-air-entrained concrete and concrete containing the air-entraining admixture under simulated field conditions. Criteria are proposed for acceptance of admixtures for use in either highway pavements or structures. The recommended procedure and acceptance criteria will guide materials engineers in evaluating and selecting air-entraining admixtures that should contribute to appropriate freeze-thaw durability and thus to good performance and long service life. The content of the report will be of immediate interest to materials engineers, researchers, and others concerned with the design of concrete mixtures for use in highway pavements and structures."--taken from Foreword, page [v].

Coal fly ash is a coal combustion by-product (CCB) that has numerous applications as an engineering material; the annual production of CCBs is nearly 82 million metric tons (90 million tons). Since the first edition of this publication in 1986, substantial information has been accumulated regarding the use of fly ash. The purpose of this document is to provide technical information about engineering applications to potential users of CCBs and to advance the use of CCBs in ways that are technically sound, commercially competitive, and environmentally safe.

"National Cooperative Highway Research Program (NCHRP) Report 819: Self Consolidating Concrete for Cast in Place Bridge Components presents recommended guidelines for the use of self-consolidating concrete (SCC) in cast in place highway bridge components. These guidelines address the selection of constituent materials, proportioning of concrete mixtures, testing methods, fresh and hardened concrete properties, production and quality control issues, and other aspects of SCC. The report also presents proposed changes to the AASHTO LRFD Bridge Design and Construction Specifications to address use of SCC for cast in place highway bridge components. The information contained in the report will guide materials and bridge engineers in evaluating, selecting, and specifying SCC mixtures for use in cast in place concrete bridge components, thereby facilitating construction, improving the working environment and safety, and reducing cost."--Publisher's description
