It is the best of times. It is the worst of times," was a Charles Dickens quote that Mac Badgett, outgoing chairman, used to launch this year's National Asphalt Pavement Association (NAPA) 54th Annual meeting. Badgett, who is with Vulcan Materials, Birmingham, AL, turned the session and gavel over to Jim Weeks of Colas Inc., Cincinnati, OH. Like the rest of the nation, the attendees at this year's meeting are waiting to see what the much-discussed Infrastructure Stimulus Package will put into motion. Since asphalt is about pavements, it's obvious that the distribution and disbursement of these stimulus funds will have a direct impact on the attendees' immediate and long-term futures.

Weeks told the audience of asphalt contractors and equipment manufacturers about how the association's national and state leaders joined forces to examine the radical conditions affecting the market. With asphalt being an oil-based product, the unprecedented oil price increases hit the market with unexpected challenges and setbacks.

Through a series of meetings, the leadership team discussed the problems and developed a strategic plan with new directions and approaches for NAPA. This new plan is engineered to focus on the issues that are critically important to the industry's health and welfare.

"We have to continue to improve our product and the workplace," Weeks told the audience. "This means that we need to follow through on our strong tradition of support for research and education. It also means that we need to achieve resolution of the fumes and silica issues."

The program is broken into multiple core strategies to support market share and gain new markets:

Effective Resolution of the Fumes and Silica Issues

Objective: Aggressively prepare for the upcoming fumes health classification and bring the silica partnership to a successful conclusion.

  • Develop and maintain key partnerships with industry partners, labor, government, and academia.

  • Provide effective oversight and management of critical research and regulatory response projects.
  • Ensure paving sector is evaluated on its own merits.
  • Bring effective closure to key remaining U.S. research projects.
  • Anticipate and respond to silica/asphalt milling initiatives by completing the testing of milling machine modifications and bringing the Partnership to a timely, successful conclusion.
  • Maintain support for timely fumes and silica research and regulatory response efforts.

Increase Highway and Airport Infrastructure Funding

Objective: Grow investments in the U.S. highway and airport infrastructure markets, and seek congressional support for highway and airfield pavement research programs.

  • Lead ongoing and immediate industry involvement in federal transportation legislation and build support for specific funding issues.
  • Work to expand, unify and strengthen coalitions and industry partnerships in support of federal transportation legislation. Consolidate transportation industry communication with common messages.
  • Support TRIP to deliver key messages to the media and general public that result in growth in transportation funds.

  • Monitor fluctuations in revenues in the Highway Trust Fund and support legislation to ensure continued growth in highway funding.
  • Promote a new long-term vision for the nation's highway system that increases investment to rehabilitate and rebuild the existing National Highway System and for new highway construction that supports the Critical Commerce Corridors initiative.
  • Build support for increasing transportation investments through an increase in the federal gas tax and other user fee revenue strategies.
  • Strengthen firewalls and budget guarantees embodied in SAFETEA-LU and Vision-100 during the annual budget and appropriations process and during reauthorization of the highway and aviation programs.
  • Fight highway funding sanctions, diversions and substitutions that reduce overall investment in highway funding.
  • Seek federal support for asphalt research.
  • Identify and take appropriate action as needed on legislation that affects the asphalt pavement industry.
  • Work with industry allies to reduce the time to fund, plan, design, and construct highway and airport projects.

NAPA has developed multiple core strategies to support market share, gain new markets and increase competitiveness. The industry will reach its goals by deploying cost-effective solutions to improve pavement performance, benefit the environment, and meet the needs of the road user.
