Lessons Learned for Using High RAP from NAPA’s Japan TourAudrey Copeland, Ph.D., P.E. Vice President, Research, Engineering, & Technology National Asphalt Pavement Association (NAPA)

Japan, on average, uses over 45 percent RAP in asphalt pavements. In 2014, NAPA set out to learn how Japan achieved such a high average through an industry tour of asphalt pavement facilities, construction sites, and roadways in Japan. A major industry initiative to learn best practices for the use of high percentages of Reclaimed Asphalt Pavement (RAP) in asphalt pavements was undertaken by NAPA in partnership with the Japan Road Contractors Association (JRCA) and Japan Asphalt Mixture Association (JAMA). This session will highlight the lessons learned, and best practices and technologies that can be implemented in the U.S. paving market.

Learning Objectives:

• Examples of best practices in Japan that allow for increased use of RAP and other pavement innovations.

• Plant and construction considerations for high-RAP use.

• Insights into how high-RAP technology might affect the future of the asphalt industry.

10:30 a.m.

NCAT Pavement Test Track Research UpdateBuzz Powell, Ph.D., P.E. Assistant Director and Test Track Manager National Center for Asphalt Technology

The Pavement Test Track is an accelerated testing facility for flexible pavements managed by the National Center for Asphalt Technology (NCAT) at Auburn University. Full-scale test sections are installed around a 1.7-mile oval and subjected to 10 million ESALs of pavement damage in two years using a fleet of heavy triple trailer trains. Better performing methods and materials are identified so that future pavements can be constructed at lower life-cycle costs. Findings in surface mix performance, structural pavement design, and pavement preservation on the track—as well as in off-track test sections near NCAT and MnROAD—will be presented.

Learning Objectives:

• Attendees will be able to compare the life cycle performance potential of asphalt pavements built with varying levels of sustainable (reclaimed and recycled) materials.

• Attendees will be able to assess the implementation of both empirical and mechanistic-empirical flexible pavement thickness designs.

• Attendees will be able to assign a life-extending benefit value to various pavement preservation alternatives.

6 59th Annual Asphalt Paving Conference

Sessions11:15 a.m.

The Benefits of Pavement PreservationLarry Galehouse Director National Center for Pavement Preservation

What will our highway system look like in 50 years? Its importance is overwhelming because highways influence the economic and social fabric of our nation. With funding at crisis levels and projected to be deficient in the years ahead, major changes are on the horizon that will influence agencies and industry alike. Old organization structures and contracting methods will be replaced with more efficient models. The focus will move from “worst first” to “preservation.” Fortunately, preservation systems exist to safeguard our highway and bridge assets. The presentation will discuss the growing importance of pavement preservation in the future.

Learning Objectives:

• The present system of financing, constructing, and maintaining our highways and bridges is inefficient and obsolete.

• Public expectations are rising and highway quality/availability must also increase.

• Agencies and industry will be held more accountable and must also improve their performance and efficiency/effectiveness.

2:00 p.m.

Superpave5—Refining Asphalt Mix Design for DurabilityRebecca McDaniel, Ph.D., P.E. Technical Director North Central Superpave Center, Purdue University

This presentation will summarize research to improve the durability of asphalt mixtures by refining the mix design process. The basic premise is to design asphalt mixtures to 5-percent air voids in the lab and compact them to 5-percent air voids in the field. By reducing the air voids in the finished mat, the intrusion of air into the pavement will be limited, thus limiting aging and improving durability. Further densification under traffic, however, must be controlled to avoid rutting. The results of two field projects utilizing the new mix design, dubbed Superpave5, will also be presented.

Learning Objectives:

• Understand the goals of the refined Superpave5 mix design procedure.

• Recognize how changes in the aggregate gradation and mixture volumetrics can improve durability.

• Describe the results of two field trials of the new mix design.

2:30 p.m.

Effects of Warm Mix Asphalt and Testing Protocol on Moisture SusceptibilityJ. Richard Willis Associate Research Professor National Center for Asphalt Technology, Auburn University

Moisture susceptibility is a common concern for many asphalt pavements. Laboratory testing has shown that WMA may be more susceptible to moisture damage than conventional HMA. The two most common test methods for determining moisture susceptibility are AASHTO T283 and AASHTO T324. This presentation shows how each method influences a mixture’s suspected moisture resistance and how they compare between the testing methods.

Learning Objectives:

• The audience will better understand the mechanism of moisture damage for asphalt mixtures.

• The audience will understand the testing protocols being used today to assess asphalt mixture moisture damage.

• The audience will understand why mixtures perform differently using the common moisture damage tests.

Airfield Paving Research UpdateJohn F. Rushing, Ph.D. Research Civil Engineer U.S. Army Engineer Research and Development Center

Asphalt is the most common paving material found on runways. Its toughness is often put to the test, especially on military airfields where fighter jet aircraft operate with tire pressures over 300 pounds per square inch. Environmental deterioration also plays a key role in these areas, with constant exposure to the elements and strict requirements to keep anything off the surface that could be ingested by a jet engine. This presentation will provide an overview of recent research programs related to airfield pavements. Topics will include efforts to update construction specifications, implement pavement preservation, and incorporate warm mix asphalt technologies.

Learning Objectives:

• How to make use of former studies instrumentation.

• Use of geophysical methods to determine the top of rock and potentially other soil layers.

• Test pits reveal important information.
