Download or read book Incorporation of Property Based Testing in Coarse Aggregate Specifications for Pavement Applications written by Magdy Abdelrahman and published by . This book was released on 2010 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The demand for pavement facilities that can handle increasing loads escalates the need for high quality aggregate material. While once plentiful, quality aggregate sources are starting to diminish. When aggregates are eliminated locally by resource depletion as well as land development that prohibits mining, the cost of construction can rise significantly. The cost of transporting quality aggregate materials from other places that comply with specifications can be very expensive. Coarse aggregate specifications for pavement mixtures for many states are outdated, with some sections dating back to around the 1930s. Specifications do not reflect the current level of knowledge concerning testing methodologies of desirable aggregate properties for pavement applications, especially at the local and low volume level. There is a need to evaluate the quality of aggregates based on the suitability of property-based testing requirements. A better understanding of testing requirements used to evaluate material properties can lead to a better utilization of local aggregate materials and reduce the reliance on diminishing high quality sources. This study investigates what property-based testing requirements have been established in current specifications as well as new areas of testing that need to be developed. A questionnaire of professionals defined a set of testing requirements for different pavement applications, which were then compared to the currently specified testing requirements. The results concluded that gaps exist in how professionals define quality aggregate compared to what current specifications define as quality aggregate. This creates the need for the inclusion of more property-based testing that could better characterize aggregates based on pavement performance. This type of characterization could open up the possibility of utilizing local materials that are normally rejected for lower volume applications.

Download or read book Guide to Cement treated Base CTB written by Gregory E. Halsted and published by . This book was released on 2006 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cement-treated base (CTB) is a general term that applies to an mixture of native soils and/or manufactured aggregates with measured amounts of portland cement and water that is compacted and cured to form a strong, durable, frost resistant paving material. Other descriptions such as soil-cement base, cement-treated aggregate base, cement-stabilized base are sometimes used. This document provides a basic guide on the use of cement-treated base (CTB) for pavement applications. This document provides on overview on the design and construction of CTB for both mixed-in-place and central plant mixed operations. A suggested construction specification is also included.

Book excerpt: The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.
