Available in PDF, EPUB and Kindle. Book excerpt: Studies were made of the effects of varying concrete production methods upon potentially durable concrete. Variations in the surface porosity, strength and air void system produced by differing finishing techniques were evaluated for typical air-entrained concretes. Large and small scale specimens were cast and effects of period and time of finishing, environmental conditions, and additions of water during finishing were evaluated using surface scaling tests, surface tensile strength tests and microscopical determination of surface air void parameters. If a concrete is to remain durable when deicing agents are used, it must have proper air entrainment and curing.

Book excerpt: This book forms the proceedings of the international workshop to be held in Essen, Germany. This workshop summarises the conclusion of the technical committee's investigations into the resistance of concrete to freeze-thaw attack, specific in this to resistance with or without de-icing chemicals. It presents the RILEM recommendations on testing the freeze-thaw and de-icing salt resistance of concrete.

Available in PDF, EPUB and Kindle. Book excerpt: The feasibility is investigated of various acoustic (sonic), nuclear, and electrical techniques for nondestructive measurement of Portland cement and bituminous concrete pavement thickness both during and after construction. Recommendations are made for equipment development and field testing of three specific methods that could potentially result in such measurements with the desired degree of speed and accuracy.

Book excerpt: The current state of knowledge with both studded tire performance and methods of assessing pavement wear is reported. An annotated bibliography is presented of all known research on this subject from the U.S. and European sources, a review and evaluation of the data and results of completed studies and recommendations for future research. The objectives of the study were confined to the following tests: (1) correlation of data on the frictional characteristics of studded tires on ice, packed snow, and on bare pavements, and (2) development of a method, or methods, of quantitative assessment of the difference in wearing and abrasive effects of studded versus unstudded tires on different types of surfaces. A stud-resistance coefficient for operation on ice was derived and all U.S. data are correlated with this parameter and ice temperature.

This book was released on 1969 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Investigation was conducted to develop a simple and fast test that could be used to identify aggregates that cause poor concrete performance when frozen. A one-cycle slow- freeze test was developed and evaluated by correlating results with the durability factor obtained from astm method c290 (the standard freezing and thawing test in water). The test method and testing procedures are presented in detail.

Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive analysis and review was undertaken of available data and information applicable to the problem of improving safety at highway rail grade crossings. A probability model was developed for forecasting the probability of accident occurrence at crossings. The model allows the separate prediction of expected accidents which involve trains and accidents which do not involve trains but occur at the crossing.

Available in PDF, EPUB and Kindle. Book excerpt: A research study was conducted to define the social and economic factors affecting intercity travel and to use the resulting relationships with existing traffic prediction tools to predict intercity travel. Data used were the external origin-and-destination surveys of 22 cities. Another source of data was the U.S. census. Trip data from the origination-destination studies were summarized by trip purposes and by increasing time rings from the study area centroids. A stepwise regression analysis computer program was used to determine the relationship between trips and social and economic data. In an alternate analysis procedure, the survey data were utilized to determine the amount and characteristics of intercity trip generation.
