Criteria for Asphalt-Rubber Concrete in Civil Airport Pavements Volume 2- Evaluation of Asphalt-Rubber Concrete Final
Report
Asphalt-rubber concrete and an asphalt concrete control were tested in the laboratory and materials characterizations were generated, including Marshall Stability,
resilient modulus, fatigue and fracture properties, creep compliance, and permanent deformation... Read More
Crumb Rubber Modifier (CRM) in Asphalt Pavements Quarterly Progress Report
This report summarizes the technical accomplishments of October 1 through December 31, 1997 quarterly report. Also this presents the activities planned for next
quarter are presented for each... Read More
Crumb Rubber Modifier: Workshop Notes (Design Procedures and Construction Practices)
The Intermodal Surface Transportation Efficiency Act of 1991, commonly referred to as ISTEA, initiated major changes in the Federal-aid highway program. Section
1038 of ISTEA contains provisions for each State to begin incorporating scrap tire rubber into their asphalt paving materials. A number of... Read More
Crumb Rubber Modifiers (CRM) in Asphalt Pavements - Structural Design of Pavements Containing CRM Materials -
Interim Report
The technological advances made in the use of crumb rubber modifier in hot-mix asphalt (CRM-HMA) indicate that if designed and placed properly, the performance of
these mixes meets or exceeds the performance of conventional HMA. This report complies the experience of various highway agencies... Read More
Crumb Rubber Modifiers (CRM) in Asphalt Pavements: Summary of Practices in Arizona, California, and Florida
Highway agencies have been evaluating crumb rubber modifier in hot mix asphalt since the 1970’s. Three agencies, AZ, CA, and FL, currently use CRM in HMA at
levels that would approach or exceed the mandate in section 1038 of the Intermodal Surface Transportation Efficiency Act of 1991. This report... Read More

Design and Construction of Asphalt Paving Materials with Crumb Rubber Modifier
Provides a concise overview of the terminology, process, products, and application for crumb rubber modifier (CRM) technology. Briefly discusses environmental and
legislative issues, history, CRM processing, wet... Read More
Design of Open-Graded Asphalt Friction Courses - Interim Report
Efforts to improve pavement skid resistance have shown the advantages of using open-graded asphalt paving mixtures. Extensive implementation of these mixtures
has been hampered, however, due to some difficulties encountered during construction and some deficiencies observed... Read More
Development of a Physical Property Specification for Asphalt-Rubber Binder
The performance of projects incorporating asphalt-rubber binders has been inconsistent. Thus, a method was needed to provide an understanding of binder physical
properties associated with the desirable performance and to quantify them for specification... Read More
Development of Asphalts and Pavements Using Recycled Tire Rubber - Phase I: Technical Feasibility
This report documents the technical progress made on the DOE funded project “Development of Asphalts and Pavements Using Recycled Tire Rubber” for the time
period covering September 1, 1994 through.... Read More
Development of Superior Asphalt Recycling Agents Phase 1: Technical Feasibility
These report documents the technical progress made on the DOE funded project “Development of Superior Asphalt Recycling Agents” for the time period covering
August 2, 1994 through August 1, 1995. Cost sharing for this study is being supplied by the Texas... Read More
Discarded Tires: Energy Conservation Through Alternative Uses
Scrap tires that are not recycled through retreading constitute a serious solid waste problem, but also offer energy conservation opportunities through their use as...

Edge Drainage in Pavement Rehabilitation
Excess moisture in the pavement structure has long been recognized as a primary cause of pavement distress. Moisture related flexible pavement failures are
characterized by excessive deflection, cracking, reduced... Read More
Effect of Crumb Rubber Particle Size and Content On The Low Temperature Rheological Properties of Binders
This paper presents a study to evaluate low temperature rheological properties of crumb rubber modified binders and the impact of the particle size and content on
such properties. Three... Read More
Effects of Rubber Additives in Asphalt Concrete
This investigation on the effects of rubber additives in asphalt mixes was accomplished in three phases. Initially, a research was made into the results of tests and uses
of this type of admixture by other agencies. Secondly, the Materials... Read More
Engineering Aspects of Recycled Materials for Highway Construction - Final Report
This report presents an assessment of environmental aspects and engineering factors related to the utilization of recycled materials in highway construction. A basic
overview and assessment of different technologies, processes, and methods for recycling of various materials into... Read More
Evaluating the Effects of the Wet and Dry Processes for Including Crumb Rubber Modifier in Hot Mix Asphalt
The conventional method of modifying asphalt cement with crumb Rubber Modifier is to blend and “react” ground CRM particles in the AC, prior to mixing with the
aggregate to produce hot mix asphalt. This is known as the “wet process.” The “dry process,” where CRM is added directly to the aggregate, has... Read More
Evaluating the Effects of Using Crumb Rubber Modifier in Hot Mix Asphalt with the Wet and Dry Processes
The objective is to compare the performance effects of adding CRM to HMA by the wet process versus the less expensive dry process, given the same CRM type, size
and amount. Also this report compares both processes to a mix without CRM. This is presented in table... Read More
Evaluation and Characterization of a Rubber Modified Hot Mix Asphalt (RMHMA) Pavement (U.S. 82- Columbus, MS)
The primary objectives of this study are 1) to evaluate the properties of a control (conventional) HMA and a rubber modified HMA (RMHMA) immediately after
construction and at various times during the first two years of the pavement’s life and 2) to compare these laboratory properties to observed in-place... Read More
