Book Synopsis Economics of Design Standards for Low-volume Rural Roads by : Clarkson Hill Oglesby
Download or read book Economics of Design Standards for Low-volume Rural Roads written by Clarkson Hill Oglesby and published by . This book was released on 1969 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: he objective of this study is to examine prevailing rural design standards to determine their economic justification. This would evaluate in depth the cost of some of the most significant design practices (for example, roadway and shoulder width and surfacing type). Resulting user benefits, such as operating, accident and time savings would be weighed against the cost of individual features. In addition to the analysis of the user-benefit relationships, the economic and social consequences to local residents, businesses and communities should be studied and a suitable means of including them in the reckoning of warranted levels of improvement should be found.
Book Synopsis Tentative Design Procedure for Riprap-lined Channels by : Alvin George Anderson
Download or read book Tentative Design Procedure for Riprap-lined Channels written by Alvin George Anderson and published by . This book was released on 1970 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study was the development of criteria and design procedures for the use of aggregate riprap linings, which consists of a layer of discrete fragments of rock of sufficient size to resist the erosive forces of the flow. The design of such riprap-lined drainage channels involves the interrelationship between the discharge, the longitudinal slope, the size and shape of the channel, and the size distribution of the riprap lining. This report describes these interrelationships and develops design criteria by which a riprap-lined drainage channel can be proportioned and the riprap lining can be specified for a given discharge and longitudinal slope. The relationships so developed have been reduced to design charts, the use of which permits rapid and simple establishment of channel shape and size as well as of the properties of the riprap lining.

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.
Book Synopsis Social and Economic Factors Affecting Intercity Travel by : Vogt, Ivers & Associates
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.

Available in PDF, EPUB and Kindle. Book excerpt: A current state-of-the-art survey is presented with regard to painting of highway structural steel. A thorough literature review was conducted and an inspection and evaluation made of more than 4,000 paint exposure tests. Paint film thickness measurement studies were made. Specific recommendations are given for selecting typical paint systems on the basis of six environmental zones, which represent the range of severity of environment in which highway steel structures are located in the United States. Model specifications are suggested for surface preparation, application, material procurement, and paint system.
Download or read book Evaluation of Studded Tires written by and published by . This book was released on 1969 with total page 84 pages. Available in PDF, EPUB and Kindle. 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.
Book Synopsis Effect of Highway Landscape Development on Nearby Property by : John H. Brinton
Download or read book Effect of Highway Landscape Development on Nearby Property written by John H. Brinton and published by . This book was released on 1969 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data were collected and disturbances were measured to determine the effects of physical disturbances by limited access highways on nearby property values. 3 types of analyses were made on the collected data: major-variable analysis, economic analysis, and interview analysis. In the major-variable analysis, relationships and correlations were examined between sound levels and sound level reductions at specific measurement points, and other variables such as sound level perception, present tree diversity, and homeowners' attitudes of buying another house next to the highway. The economic analysis evaluated the effect of highway disturbances and landscape/landforms on property values. The interview analysis was used to evaluate specific complaints or disturbances.
