Download or read book Factors Influencing Flexible Pavement Performance written by Robert L. Kondner and published by . This book was released on 1966 with total page 824 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flexible pavement performance, as expressed by the present serviceability index (PSI) is related to local factors, such as surface course thickness, base course thickness, subbase course thickness, axle load and number of load applications. On the premise that functional pavement design should recognize the relationship between these factors and performance, data from 134 AASHO road test flexible pavement sections were examined for behavioral trends. This resulted in a mathematical expression on which it is theorized that performance, expressed in terms of PSI, can be incorporated into design procedures.

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.

Download or read book Social and Economic Factors Affecting Intercity Travel written by Vogt, Ivers & Associates and published by . This book was released on 1969 with total page 88 pages. 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.

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: Structural Behavior of Asphalt Pavements provides engineers and researchers with a detailed guide to the structural behavioral dynamics of asphalt pavement including: pavement temperature distribution, mechanistic response of pavement structure under the application of heavy vehicles, distress mechanism of pavement, and pavement deterioration performance and dynamic equations. An authoritative guide for understanding the key mechanisms for creating longer lasting pavements, Structural Behavior of Asphalt Pavements describes the intrinsic consistency between macroscopic performance and microscopic response, structure and material, as well as global and local performances, and demonstrates the process of pavement analyses and designs, approaching science from empirical analyses. Analyzes the external and internal factors influencing pavement temperature field, and provide a review of existing pavement temperature prediction models Introduces a “Bridge Principle through which pavement performance and fatigue properties are consolidated Defines the intrinsic consistency between macroscopic performance and microscopic response, structure and material, as well as global and local performance Summaries the mechanistic response of pavement structure under the application of heavy vehicle, distress mechanism of pavement, pavement deterioration performance and dynamic equations, and life cycle analysis of pavement

Download or read book Factors Influencing Safety at Highway rail Grade Crossings written by David W. Schoppert and published by . This book was released on 1968 with total page 136 pages. 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.
