2015 Minnesota Legislative Session Update

Jim Wafler, Consultant

Minnesota State Capitol

With just over six weeks to go in the 2015 session of the Minnesota Legislature (the required adjournment date is May 18), on the transportation finance front, the future looks rather bleak right now.

Both the DFL-controlled state Senate and the Republican-controlled state House have now officially unveiled their omnibus transportation proposals. The Senate bill (S.F. 87) to a large extent mirrors the Governor’s initial ten-year proposal: (a) a 6.5% gross receipts tax on wholesale fuel, directing $1 billion over 4 years to the Transportation Economic Development and Corridors of Commerce programs of MnDOT; (b) the metro transit sales tax would be increased by .75% and apply to all metro counties; (c) tab fees 1.25% base tax would be increased to 1.5%, and there would be a slight increase in minimum fee for older cars. Annual new revenues would be almost $800 million, and a large share of it would go to roads and bridges; in addition the Senate proposes General Obligation bonds of $567 million for local roads and bridges.

The Economic Value of Pavement Overlay Alternatives

The Economic Value of Pavement Overlay Alternatives

The majority of the US highway roadway system has been completed for many years, thus requiring agency resources to be focused on maintaining and rehabilitating existing pavements. Economic analysis of pavements must consider initial costs, design life, maintenance costs over the life of the pavement and salvage value at the end of its life-cycle. This case study examines five pavement rehabilitation methods for asphalt roadways using equivalent 20-year pavement overlay designs in contrast to the 40-year life cycle designs traditionally used for new construction and full-depth reconstruction. These designs will be judged under the scrutiny of the economic value of the pavement from the beginning to the end of the 20-year pavement life-cycle.

Best Practices: Control Worker Exposure to Respirable Crystalline Silica during Asphalt Pavement Milling

This document represents more than ten years of collaborative research by labor, industry, and government to reduce respirable crystalline silica exposure during asphalt pavement milling in highway construction. The collaborative research began when the Silica/Asphalt Milling Machine Partnership was formed at the 2003 National Asphalt Pavement Association (NAPA) Annual Meeting, and studies on milling machine dust controls began later that year.

Recent Conference Summaries:

TERRA Pavement Conference

The TERRA Pavement Conference was held on February 12th. Buzz Powell with NCAT presented on the partnership with MnDOT and NCAT. Pavement preservation is going to be a common focus between the partnership. In the breakout session of the conference, Mike Anderson with the Asphalt Institute presented on asphalt aging and the timing of preventive maintenance. Cell 24 at MnROAD and TH56 were used as case studies. Maria Masten with MnDOT presented an overview of concrete overlays. This included the types of concrete overlays, projects in Minnesota, resources for concrete overlays, TH24 and current/future efforts.

National Center for Asphalt Technology Test Track Conference

The 2015 pavement test track conference at the National Center for Asphalt Technology (NCAT) was from March 3-5. This conference consisted of technical sessions discussing their program and various implementations of the research. A tour of the main test track was held the first day and had staff at each of the sections. The second day consisted of a tour of their new test section Lee Road 159. The research at this section has a common theme of pavement preservation. Several preventative methods are being compared to the control section. Ben Worel with MnDOT presented on the last day about the MnROAD and NCAT partnership. The presentation included cost savings for various research at MnROAD. There will be pooled fund research available for MnROAD as well as a separate pooled fund for the MnROAD and NCAT partnership.

Association of Asphalt Pavement Technologists (AAPT) Annual Meeting

The conference consisted of several presentations of varying session topics. AAPT was a three day conference with speakers in academia, government and industry. Several state DOT speakers presented on the implementation of specifications for new technologies. Many of these presentations discussed the use of RAP/RAS. Performance testing continues to be a hot topic for asphalt technology.

The topics for the conference included:

  • Implementing specifications for new technologies
  • Fatigue of RAP mixes
  • Oxidative aging and cracking
  • Fatigue of asphalt materials
  • Rejuvenators
  • Mix design and performance
  • Modulus/cracking of mixtures

The AAPT group are leaders in advancing asphalt paving technology for more than 80 years. They are a dedicated group for professional development that share best practices and latest developments in the asphalt paving industry.
