This STAR on asphalt materials presents the achievements of RILEM TC 206 ATB, acquired over many years of interlaboratory tests and international knowledge exchange. It covers experimental aspects of bituminous binder fatigue testing; the background on compaction methods and imaging techniques for characterizing asphalt mixtures including validation of a new imaging software; it focuses on experimental questions and analysis tools regarding mechanical wheel tracking tests, comparing results from different labs and using finite element techniques. Furthermore, long-term rutting prediction and evaluation for an Austrian road are discussed, followed by an extensive analysis and test program on interlayer bond testing of three different test sections which were specifically constructed for this purpose. Finally, the key issue of manufacturing reclaimed hot mix asphalt in the laboratory is studied and recommendations for laboratory ageing of bituminous mixtures are given.

Measures of the within- and between-laboratory variability associated with the standard test method for determining the compressive strength of cylindrical portland cement concrete specimens have been derived from data obtained in three interlaboratory testing programs operating in western Canada. These data have been analyzed using appropriate ASTM standard practices to provide estimates of repeatability (within-laboratory) and reproducibility (between-laboratory) standard deviation values and corresponding precision indices (difference "two"-standard-deviation limits). Both measures of variability have been found to vary linearly with the compressive strength of the test concrete, and hence the standard deviation and precision values are best expressed as linear functions of this strength. The resulting reproducibility (between-laboratory) precision index values are particularly important in that they provide guidance as to the level of the component of variability to be expected when two or more laboratories are testing the same batch of portland cement concrete for its compressive strength.

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.

A comprehensive guide to the most useful geotechnical laboratory measurements Cost effective, high quality testing of geo-materials is possible if you understand the important factors and work with nature wisely. Geotechnical Laboratory Measurements for Engineers guides geotechnical engineers and students in conducting efficient testing without sacrificing the quality of results. Useful as both a lab manual for students and as a reference for the practicing geotechnical engineer, the book covers thirty of the most common soil tests, referencing the ASTM standard procedures while helping readers understand what the test is analyzing and how to interpret the results. Features include: Explanations of both the underlying theory of the tests and the standard testing procedures The most commonly-taught laboratory testing methods, plus additional advanced tests Unique discussions of electronic transducers and computer controlled tests not commonly covered in similar texts A support website at www.wiley.com/college/germaine with blank data sheets you can use in recording the results of your tests as well as Microsoft Excel spreadsheets containing raw data sets supporting the experiments
