This book was released on 1977 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper describes the development of structural layer coefficients for open graded asphalt emulsion surfacing layers which can be used with the AASHO pavement design method, as modified by the U.S. Forest Service, Region 6. A field survey conducted to document the history, performance and material characteristics of in-service pavements is described and this information together with a survey of experienced users is used to determine the most important factors affecting the design thickness for the pavements. Traffic, base type, temperature and drainage design all are important to determine the pavement thickness. Two procedures used for the development of structural layer coefficients are described. The first procedure uses the information from the performance survey and the AASHO pavement design method to determine appropriate layer coefficients for three in-service roads. The second procedure is a fundamental approach based on layered elastic theory and using information from the field survey. This procedure is useful for the analysis of the pavement in the fully cured or partially cured state. Although a conservative approach was used for both procedures, the developed layer coefficients are greater than the values used in the current design procedure. This indicates that modification of the current values is appropriate. A tabled presentation of layer coefficients is proposed which considers only those factors found to be important for the determination of design thicknesses. The importance of good quality control and specifications is stressed and a listing of current specifications is included.

Download or read book Evaluation of Procedure to Assign Structural Layer Coefficients for Use in Flexible Pavement Design written by Harold L. Von Quintus and published by . This book was released on 2007 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Kansas Department of Transportation (DOT) uses the 1993 DARWin version of the 1986 AASHTO Guide to design flexible pavements and rehabilitation strategies of flexible pavements. One of the inputs needed for the flexible pavement design procedure is the structural layer coefficient for each pavement layer. The Kansas DOT procedure to assign structural layer coefficients was developed years ago and based on an analysis of flexible pavement performance data and layer properties. It has been recently suggested that the Kansas DOT increase the structural layer coefficients because of changes in material and construction specifications. Different procedures can be used to estimate the structural layer coefficients for flexible pavement design. As part of the study entitled Determination of the Appropriate Use of Pavement Surface History in the KDOT Life-Cycle Cost Analysis Process an evaluation of the procedure that Kansas DOT uses to assign structural layer coefficients to different pavement materials was completed. This report provides the results of that evaluation.

Download or read book Asphalt Pavements written by Patrick Lavin and published by CRC Press. This book was released on 2003-09-02 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: Asphalt Pavements provides the know-how behind the design, production and maintenance of asphalt pavements and parking lots. Incorporating the latest technology, this book is the first to focus primarily on the design, production and maintenance of low-volume roads and parking areas. Special attention is given to determining the traffic capacity, required thickness and asphalt mixture type for parking applications. Topics covered include: material information such as binder properties, testing grading and selection; construction information such as mixing plant operation, proportioning, mixture placement and compaction; and design information such as thickness and mixture design methods and guidelines on applying these to highways, city streets and parking Areas. It is an essential practical guide aimed at those engineers and architects who are not directly involved in the asphalt industry, but who nonetheless need to have a good general knowledge of the subject. Asphalt Pavements provides a novice with enough information to completely design, construct and specify an asphalt pavement.
