In Brief

A new videotape provides a step-by-step look at the Superpave mix design process. Topics covered include: materials selection, aggregate blending, specimen preparation, the Superpave gyratory compactor, and mix analysis.

An Overview of the Superpave System

Looking for a concise overview of the Superpave system? Then you'll want to get a copy of FHWA's new brochure, The Superpave System: New Tools for Designing and Building More Durable Asphalt Pavements.

States Receive Next Item in Pooled-Fund Purchase

All 50 States have now received a pressure aging vessel (PAV), as part of the pooled-fund purchase of Superpave equipment. The purchase was arranged by the Federal Highway Administration (FHWA), using funds provided by the States.

Pavement Performance Advisory Committee Meeting States' Needs

Making long-term pavement performance (LTPP) products easier to use and more accessible to highway agencies was the focus of the Pavement Performance Advisory Committee (PPAC) meeting held recently in Irvine, California.

LTPP Product Preview: The Future is Now

The Federal Highway Administration (FHWA) has prepared a brochure highlighting the products that have resulted--or will result--from the long-term pavement performance (LTPP) program, a 20-year study of in-service pavements across North America. The goal of the LTPP program is to develop improved pavement technologies for designing, building, and maintaining roads that will last longer. Products include information, computer software, analysis procedures, testing procedures, and design procedures and guidelines that respond to needs identified by highway agencies and industry.

Superpave Centers Meet to Define Roles

Now that the five regional Superpave centers are outfitted with the full range of Superpave test equipment, how will they be used to jump-start the move to the next phase of Superpave implementation? What will their roles be? How will they be financed?
