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.
Download or read book A Surface Performance graded SPG Specification for Surface Treatment Binders written by Lubinda F. Walubita and published by . This book was released on 2005 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presently, surface treatment design and material selection is based on traditional specifications and experience, which are not performance-based and sometimes result in inadequate performance of the surface treatment. In 2000 the first phase of a Texas Department of Transportation (TxDOT) research project developed a surface performance-graded (SPG) specification for the selection of surface treatment binders (Research Report 1710-1). The SPG specification is performance-based and utilizes binder properties directly related to surface treatment performance and associated distress. The specification takes into account environmental conditions, aging effects of the binder, visco-elastic behavior, and reliability. The objective of this second phase of the project was to investigate and establish the validity and applicability of the proposed SPG specification, make modifications where necessary, and, finally, recommend the SPG specification for practical implementation. The research methodology involved highway section identification, laboratory testing including SPG grading, performance monitoring, and comparison of the SPG binder grades to actual field performance. Factors included in the experimental design were binder type and suppliers, environment, aggregates, and traffic. Analyses of the results showed that there is generally a good correlation between the proposed SPG specification and actual field performance. Overall, the results are indicative that the SPG specification is functional and if properly applied, the specification promises to be a relatively cost-effective method for selecting binders to ensure adequate surface treatment performance. However, further validation is recommended, possibly with controlled test sections to fully investigate the effects of design, construction, and quality control processes and address some of the deficiencies of the specification.

Download or read book Rejuvenators Rejuvenator Sealers and Seal Coats for Airfield Pavements written by and published by . This book was released on 2003 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are a number of proprietary rejuvenator, rejuvenator/sealer, and a seal coat materials currently available. It should be noted that throughout this report file term rejuvenator will be used to describe both rejuvenator and rejuvenator/sealer materials, because the primary purpose in this study was to use these materials to rejuvenate the asphalt pavement. Because of the proprietary nature of these materials, specifications that use performance-based requirements rather than material requirement specifications are highly preferred. One important requirement in the development of this type of specification is a field performance comparison of the various materials with known application and material property parameters. The objective of this study was to investigate the comparative field performance of various rejuvenators and seal coat materials. The field performance of these materials was evaluated over a period of more than 1 year. The materials evaluated in this study were proprietary products. The study was not intended to determine the best or optimum rejuvenator or seal coat material but was intended to provide information for the development or updating of guide specifications for file use of these types of materials. The scope of this study was to evaluate several types of coal-tar- and petroleum-based rejuvenators and seal coat materials. The materials were placed at two airfields and their effect on the binder properties of the treated pavement was compared to untreated areas. The field performance of the rejuvenator and seal coat materials was evaluated through their effects on skid resistance, texture, and changes on visual appearance. This report covers the placement and performance of the materials included in this study.
Download or read book Application Rate Adjustments for Seal Coats in Texas written by Darline C. Goehl and published by . This book was released on 2018 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seal coats are a very important preventive maintenance method used throughout Texas. Through the preventive maintenance program, about 16,000 lane miles a year are routinely resurfaced with a seal coat by contracts and about 3,000 lane miles per year of seal coats are placed with state forces. Additionally, seal coats are used in intermediate layers during construction to seal the pavement structure. This is a significant investment of over $300 million annually. For more than 40 years, there has been little change in the design and construction practices, including equipment used to place the asphalt or aggregate. With little to no changes in design and construction methods, Texas continues to see the same problems, such as rock loss, flushing, and bleeding reoccurring. New technologies are being developed that could potentially reduce these types of problems. There have been recent new developments for asphalt distributors due to the performance-based warranty specification being used by the New Zealand Transport Agency. The asphalt distributor improvements include the ability to use up to eight different transversely varying application rates at normal operating speed. This is extremely useful to apply the optimal shot rate when surface conditions change. In addition to this, high definition video systems and scanners can map and document existing texture conditions to define the required spray bar pattern.
