The National Center for Asphalt Technology at Auburn University (NCAT) will host the third Pavement Test Track Conference on Feb. 9-11, 2009 at the Auburn Marriott Opelika Hotel and Conference Center at Grand National. The two-day meeting will highlight research findings from NCAT's 1.7-mile test track. Participants will have a chance to tour the track, hear researchers and Department of Transportation (DOT) engineers discuss their latest results and observe how they are being put into practice.

Discussion will include laboratory tests that best predict permanent deformation and cracking resistance in asphalt mixes; how surface treatments can be used to meet the Leadership in Energy and Environmental Design (LEED) certification requirements for solar reflectivity index; and how lab tests can be used to estimate in-service friction behavior of asphalt mixes.

Conference attendees will learn how mechanistic-empirical pavement models can be calibrated and refined with structural section experiments; about the design, construction and performance of economical mixes formulated with more than 40 percent reclaimed asphalt pavement (RAP); and how dual-layer porous friction courses improve drainage and highway noise.

NCAT operates five semi-tractor trailers for 16 hours a day, five days a week, on the test track to reproduce similar levels of traffic and stress a highway would experience in 15 to 20 years, or 10 million equivalent single axle loads (ESAL). The track is made up of 45 different 200-foot sections for field performance comparisons.

Nestled on 2,000 acres of lakefront countryside, the Auburn Marriott Opelika Hotel and Conference Center at Grand National is an exceptional golf and business retreat located in the historic town of Opelika, Ala.

Event registration will open in November 2008 online at Room reservations may be made by calling 800-593-6456.
