Events calendar

The use of warm mix asphalt (WMA), reclaimed asphalt pavement (RAP), and recycled asphalt shingles (RAS) has significantly increased in recent years due to construction costs and environmental issues. This course is designed to provide information useful for designing mixes and making decisions about the use of WMA, RAP, and RAS. Information will be provided on testing, performance, and cost for each of these processes. This course is valuable for individuals involved in the HMA industry, including material producers, contractors, consultants, and various agency personnel.

Goals and Objectives

The purpose of this three-day workshop is to provide a basic understanding of the advantages of using WMA, high RAP, and RAS, and to provide guidance in material testing and mix design.

Program Content

This course consists of three days of intensive lectures, laboratory demonstrations, and hands-on training with these products in the laboratory. There will also be an optional tour of the NCAT Pavement Test Track to observe the performance of test sections using these materials. A brief outline of the course follows.

Lecture:

• Overview and discussion of WMA technologies
• Sources and control of RAP and RAS
• RAP/RAS properties
• Mix design procedures
• Performance tests: discussion of procedures
• Production and placement of WMA/RAP/RAS
• Guidance for field quality control/quality assurance
• Observed performance of high RAP/RAS mixes
• Observed performance of WMA mixes
• Class exercise: economics of WMA/RAP/RAS
• Proposed guide specifications for high RAP, WMA, etc.
• Status of implementation and open discussion

Laboratory and Test Track:

• Handling various WMA technologies: foaming, chemical, organic
• Performance test: observe performance test equipment and operation in the lab
• Material testing and mix design
• Tour of test track

Materials

Each participant will be provided a binder containing a print-out and electronic copy of the PowerPoint presentations.
