To wrap up its 2-year anti-icing test and evaluation project (TE 28), FHWA hosted a symposium on anti-icing technology in October in Estes Park, Colorado. The more than 200 participants represented State and local highway agencies, academia, consultants, suppliers, and manufacturers.
To emphasize the partnership involved in implementing the Superpave system, FHWA recently introduced a new Superpave logo. The logo shows the principal partners in the Superpave implementation program--namely, the American Association of State Highway and Transportation Officials, the highway industry, and FHWA. "Superpave 2000" signifies the target date for nationwide implementation of the Superpave volumetric mix design procedures.
The Federal Highway Administration (FHWA) has concluded its Test and Evaluation Project 22 on the Georgia digital faultmeter. Eighteen State departments of transportation and the American Concrete Paving Association participated in the study. The majority of participants found the digital faultmeter to be a significant improvement over other methods.
The State of Illinois is putting its money on Superpave equipment. Last year, it spent $325,000 to purchase 13 Superpave gyratory compactors for its districts. The Superpave gyratory compactor is required for designing Superpave mixes.
Engineers and managers responsible for designing, building, and maintaining roadways will want to attend the upcoming long-term pavement performance (LTPP) conference, "Improving Pavements with LTPP: Products for Today and Tomorrow." Scheduled for March 26-28, the conference will provide an update on the LTPP program's accomplishments and early products. The conference also has the goal of enhancing communication among the LTPP partners--highway agencies, academia, industry, and FHWA.
Pavement deflection measurement and analysis are valuable tools that help pavement design engineers learn more about the properties of various pavements. To enhance pavement engineers' knowledge of automated deflection measurement and backcalculation, the National Highway Institute (NHI) offers a pavement deflection analysis course
The National Information Management System (NIMS) managed under FHWA's long-term pavement performance (LTPP) studies now includes actual traffic data collected at monitored general pavement studies (GPS) sites. The data have been collected by State and provincial highway departments since 1990, but accessibility to the data was delayed until standardized processing procedures could be developed. Until now, the only traffic information available from NIMS consisted of historical estimates based on truck weight and volume information collected from roadways similar to the GPS sites.
