Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to materials and construction engineers, and others interested in the use of rapid test methods for asphalt concrete and portland cement concrete. Information is provided on the various test methods in use for process control and acceptance of these materials, as well as methods under development. State experience with these procedures, as well as discussions from the literature, are presented. There is growing use of rapid test methods for asphalt concrete and portland cement concrete in highway construction. This report of the Transportation Research Board describes the current state of the practice with respect to the use of rapid test methods for these materials. Experience with short-cut and rapid test procedures for process control and acceptance is summarized, and a general description of the methods, their advantages and disadvantages, and their time and labor requirements are discussed based on a review of the literature and a survey of the states.

Available in PDF, EPUB and Kindle. Book excerpt: Testing of materials and manufactured items is a key element in the process from standard specifications though control and verification during manufacture to trade in actual products. Cooperative agreements and networks are being set up covering reference materials and calibration. This process is becoming more urgent with the development in the European market and other international developments. This book presents international views on this fast changing field, with the main themes of: technical components of test quality; quality assurance in testing laboratories; laboratory accreditation and transnational recognition of test results.

Available in PDF, EPUB and Kindle. Book excerpt: A literature survey and limited study of laboratory concretes were conducted to evaluate various methods for predicting concrete strengths at 28 days based on procedures for accelerated strength development or measurement of strength of normally cured specimens at early ages. A review of the literature was also made to assess the usefulness of procedures for the direct determinations of water and cement contents in quality control of hydraulic cement concrete. It is concluded that although general relationships exist as reported in the literature, none of the procedures are sufficiently precise for use in quality control or acceptance testing by the Virginia Department of Highways & Transportation. The amount of calibration testing for projects normally built by the Department would be prohibitive. Any application of reduced pay factors for strength in a statistical specification must be based on tests made at the age designated in the specification. The literature survey shows that in their present state of development existing procedures for the direct determination of water and cement in plastic concrete are not sufficiently fast or precise to be useful for quality control of hydraulic cement concrete. It is recommended that further evaluation of such procedures by the Virginia Department of Highways and Transportation be deferred until results of studies now being made for the FHWA are available. The results of 14-day and 28-day tests on the same field concretes reveal that the ratio of strengths at these two ages often varies significantly from the assumed value of 0.85. Thus, it is recommended that the practice of accepting concrete on the basis of 14-day strengths be discontinued unless the value at 14 days is equal to the required value at 28 days.
