1.1 This practice describes procedures for measuring the chemical emissions of volatile and semi-volatile organic compounds (VOCs and SVOCs) from spray polyurethane foam (SPF) insulation samples in a large-scale ventilated enclosure. 1.2 This practice is used to identify emission...
4.1 The test method described is useful as a rapid, nondestructive technique for determining the in-place density of compacted asphalt mixtures. 4.2 With proper calibration and confirmation testing, the test method is suitable for quality control and acceptance testing of compacted asphalt mixtures...

1.1 The use of artificial lighting is often required to study the responses of living organisms to contaminants in a controlled manner. Even if the test organism does not require light, the investigator will generally need light to manipulate the samples, and the test might be conducted under the...
Construction Equipment Management for Engineers, Estimators, and Owners, Second Edition has been extensively rewritten to not only bring it up to date with the state of current practice, but also to serve as a textbook for university courses in construction engineering and...
