This book was released on 2013 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to evaluate the effect of binder type, mastic, and aggregate type on the low-temperature cracking characteristics of asphalt mixtures. Six different performance grade (PG) binders were utilized for this study: PG64-28, PG64-28 with poly phosphoric acid, PG64-34 SBS, PG76-22 SBS, a terminal blend asphalt rubber, and PG64-28 with 2 % latex. Each binder was tested to determine its low-temperature cracking resistance using the asphalt binder cracking device (ABCD) and the Superpave tests. A Superpave 9.5 mm mixture was designed using each of the six binders for this study and two sources of aggregates (crushed stone and gravel). Each mixture was then tested for low-temperature cracking resistance using the asphalt concrete cracking device (ACCD). Mastics corresponding to each mixture were tested for low-temperature cracking resistance using the ABCD. Analysis of the results showed that the AASHTO critical cracking temperature had a strong correlation with the ABCD binder and mastics results, but did not correlate well with the mixture tests. Mastic testing generally did not correlate well with the mixture test results. ABCD and ACCD tests results indicated that they were sensitive to binder type, aging time, and aggregate types.

Book Synopsis Durability and Performance Characteristics of Hot Mix Asphalt Containing Polymer Additives by : Robert Y. Liang
Download or read book Durability and Performance Characteristics of Hot Mix Asphalt Containing Polymer Additives written by Robert Y. Liang and published by . This book was released on 2001 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ohio Department of Transportation has adopted the hot mix asphalt concrete containing polymer modifiers for use in the interstate highway pavement. Among the various reasons cited for the adoption of polymer modifiers are the favorable field experiences by ODOT, extensive literatures reporting enhanced performance, such as rutting resistance, low temperature thermal cracking resistance, and possibly fatigue endurance. However, despite these favorable findings, there are still cases involving premature failure of hot mixtures containing polymer modifiers. Concerns regarding optimum polymer content, compatibility between polymer additives and asphalt cement, proper mixing and compaction procedure remain to be resolved. Furthermore, performance based specifications to ensure production of desirable final asphalt concrete product require additional development. Questions regarding the suitability of Superpave binder testing procedures for the polymer-modified binders need to be clarified.

Download or read book Evaluation of the Effects of Asphalt Binder on the Properties of Hot Mix Asphalt at Intermediate Temperatures written by Haifang Wen and published by . This book was released on 2011 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: The asphalt binder is an essential component of asphaltic mixtures. The performance of an asphaltic mixture is directly related to mechanical characteristics of the binder. With the development of new material characterization methods for both asphalt binder and asphaltic mixture, there is a need to re-evaluate the relationship between the properties of binders and asphaltic mixtures such that a proper understanding and selection of an asphalt binder can be made to improve the performance of an asphaltic mixture. In this study, the effects of asphalt binder properties on asphaltic mixtures at intermediate temperatures were evaluated based on recent developments on material characterization methods for both binder and asphaltic mixture. Five asphalt binders and five asphalt mixtures containing these binders with one aggregate were tested. Four of the binders were based on a modification of a base binder with different techniques. Complex shear modulus and monotonic constant shear-rate tests were conducted on asphalt binders, whereas dynamic modulus and indirect tensile strength tests were conducted on the mixtures. The effects of modification techniques on the properties of asphalt binders and the relationships between the properties of binders and asphaltic mixtures were evaluated in this study.

Book Synopsis Water Sensitivity of Asphalt-aggregate Mixes by : Ronald L. Terrel
Download or read book Water Sensitivity of Asphalt-aggregate Mixes written by Ronald L. Terrel and published by National Research Council. This book was released on 1994 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research presented in this report was conducted to identify the important factors influencing the water sensitivity of asphalt paving mixtures, and to develop a test method to evaluate water sensitivity of asphalt concrete mixtures for mix design. The test method was to be performance related. A review of current procedures revealed that no single method was suitable for evaluation and related to field performance. Based on a hypothesis that air voids in the mixture may be the major source and cause of water damage, a test system was developed to evaluate the major factors that influence water sensitivity. The Environmental Conditioning System (ECS) was used to develop a test procedure that includes specimen preparation; measurement of permeability using air, water, or both; vacuum wetting; cycling at various temperatures; and continuous repeated loading while monitoring resilient modulus after each conditioning cycle.

Book Synopsis Mechanical Properties of Warm Mix Asphalt Prepared Using Foamed Asphalt Binders by : Ala R. Abbas
Download or read book Mechanical Properties of Warm Mix Asphalt Prepared Using Foamed Asphalt Binders written by Ala R. Abbas and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Hot mix asphalt (HMA) is a mixture containing aggregates and asphalt binders prepared at specified proportions. The aggregates and asphalt binder proportions are determined through a mix design procedure such as the Marshall Mix Design or the Superpave Mix Design methods. Overall, the goal of determining such proportions is to establish an HMA mixture that will meet specific performance criteria. In addition, it is imperative to ensure that the asphalt binder will fully coat the aggregates and that the resulting mixture is workable and compactable. In order to ensure sufficient aggregate drying and coating, both the asphalt binder and the aggregates are heated to elevated temperatures ranging between 300oF and 325oF. The use of such high temperatures would result in lowering the viscosity of the asphalt binder which is the main factor affecting the coating and workability of asphalt mixtures. In recent years, a new group of technologies have been introduced to the United States that allow producing asphalt mixtures at temperatures 30 to 100oF lower than what is used in HMA. This group of technologies is commonly referred to as Warm Mix Asphalt (WMA). They are promoted as environmentally friendly green alternatives to HMA mixtures as they produce lower greenhouse gas emissions. This new group of technologies aims at reducing the viscosity of the asphalt binder through the addition of organic or chemical additives or by introducing cool water into the heated molten asphalt under controlled temperature and pressure conditions, resulting in so-called foamed asphalt binder. As a consequence, lower temperatures are needed during production for the asphalt binder to be absorbed by the aggregates.
