TRB’s SHRP 2 Tuesdays Webinar: SHRP 2 Composite Pavement Systems (R21)

As part of the SHRP2 Tuesdays Webinar Series, TRB conducted a webinar on December 3, 2013 from 2:00 p.m.-3:30 p.m. ET that explored the SHRP 2 project called Composite Pavement Systems (R21).

View the recorded webinar.

This webinar explored the SHRP 2 Composite Pavement Systems research project, which provides guidelines and validated models, techniques, and specifications for using two composite pavement systems: a relatively thin, high-quality, hot-mix asphalt layer over a Portland cement concrete (PCC) structural layer; and a relatively thin PCC surface on top of a second, less-expensive, recycled PCC layer.

Composite pavements have been demonstrated to increase pavement service life while providing favorable surface characteristics and structural capacity. However, objective studies of their use and installation have been inadequate to support widespread adoption. This project included the development of validation procedures and produced documentation to assist transportation agencies with installation and maintenance of composite pavement systems that are long-lasting and have predictably low life-cycle costs.

Webinar Presenters:

• Michael Darter, Applied Research Associates, Inc.
• Stephen J. Cooper, Federal Highway Administration (FHWA)
• Jameelah Hayes, American Association of State Highway and Transportation Officials (AASHTO)

Moderated by: James Bryant, Transportation Research Board

Webinar Outline:

• Part 1: Brief overview of SHRP 2 mission, objectives of the Renewal focus area and related SHRP 2 research.
• Part 2: SHRP 2 researchers introduce the results, concepts, and products and experience gained from development and testing the project outcomes.
• Part 3: FHWA's perspective regarding the Composite Pavement Systems Project.
• Part 4: AASHTO’s perspective regarding the Composite Pavement Systems Project.
• Part 5: Question and answer session.

The first 60 minutes of the webinar was for presentations and the final 30 minutes was reserved for audience questions.

Learning Objectives:

• To understand ways to investigate the design and construction of a new composite pavement system.
• To understand the behavior, material properties, and performance of each type of composite pavement under various climate and traffic conditions.
• To understand how the SHRP 2 project has validated updates to the applicable structural, climatic, material, performance prediction models, and design algorithms including:
• AASHTO Mechanistic-Empirical Pavement Design Guide Manual of Practice (MEPDG)
• DARWin-ME
• CalMe
• National Cooperative Highway Research Program (NCHRP) 1-41 reflection cracking
• NCHRP 9-30A rutting
• Lattice Bonding model
• To understand the R21 project, the recommendations for construction specifications, installation techniques, life-cycle costing, and the related training materials.
