The Federal ‘Fast ACT’ & Opportunities for Minnesota Cities

On Dec. 4, 2015, President Obama signed into law a $305 billion, 5-year federal surface transportation act known as the “FAST” Act (Fixing America’s Surface Transportation Act). This legislation serves as the blueprint for how the states will spend their Federal-aid highway dollars over the next five years. The FAST Act will be remembered for two significant changes: the significant investments to improve freight movement on the National Highway System and the increased local control given to the states for spending Federal-aid highway dollars.

Thinlay Specification Coming Soon

MAPA is currently working with agency and industry to develop a specification for a thin asphalt overlay to be used as a pavement preservation method.

Several pavement preservation techniques are available; of those Thinlays offer a high value to public and private pavement owners alike. Thinlays are asphalt mixes that can be placed at a thickness between 5⁄8 and one inch. Thinlays for pavement preservation offer economic, engineering, and sustainability benefits.

Thinlays share many of the benefits seen in overlays and inlays: extended pavement life, smooth ride, a modest improvement in pavement strength, enhanced safety, and responsible use of natural resources through reuse and recycling. Thinlays are versatile, cost beneficial and compatible with asphalt pavements.

Project Selection Criteria:
Thinlays are designed as a pavement preservation tool for use on low volume roadways (less than 3 Million Equivalent Single Axle Loads [ESALs]). Surface distresses and structural adequacy of the road must be evaluated prior to using pavement preservation treatments, including Thinlays. Thinlays are asphalt mixes that can be placed at a thickness between 5⁄8 and one inch on a well prepared surface. The pavement being overlaid may be milled or unmilled depending on surface distresses. The pavement should not show signs of structural distress requiring a more extensive rehabilitation.

Minnesota is Honored for its 14th Perpetual Pavement Award

PPA_2015_winnersEight Departments of Transportation Honored for Success of Long-Life Asphalt Roads

Lanham, Md. — The Asphalt Pavement Alliance (APA) has recognized eight state departments of transportation with the 2015 Perpetual Pavement Award for high quality, long-life asphalt pavements.

The award is presented to state transportation departments and local agency road owners for well-performing asphalt pavements that are at least 35 years old with proven high-quality structural design. To earn the award, the pavement must have not suffered a structural failure, and it should have an average interval between resurfacing of no less than 13 years. The road must demonstrate the characteristics expected from a long-life, Perpetual Pavement design: excellence in design, quality in construction, and value to taxpayers.

Minnesota Department of Transportation received the award for a 3.24-mile, two-lane section of SR 71 in Beltrami County from milepost 317.28 to 320.52. MnDOT has had 14 pavements recognized with the Perpetual Pavement Award, more than any other state or agency.

Steady Increase in Sustainability of Asphalt Pavements

Recycled Materials, Warm-Mix Asphalt Show Steady Growth Increasing the Sustainability Profile of Asphalt Pavements

Lanham, Md. — Nationwide, asphalt pavement mix producers continue to improve the sustainability profile of America’s roads through the incorporation of recycled materials and the use of energy-saving warm-mix asphalt technologies.

According to the latest survey of asphalt mix producers conducted by the National Asphalt Pavement Association (NAPA) in partnership with the Federal Highway Administration (FHWA), more than 75 million tons of recycled materials — primarily asphalt pavement material reclaimed from old roads and parking lots and recycled asphalt roofing shingles — was put to use in new asphalt pavement mixtures during the 2014 construction season. Click here to read more

MAPA Contractors Workshop

2016ContractorsWorkshopThe MAPA 2016 contractors workshop was held at the Earle Brown Heritage Center in Brooklyn Center, MN. There were a total of 142 registrations and 14 sponsor booths. This year the topics were focused on the 2016 Legislative Session, Wisconsin high RAP pilot projects, State Aid projects, specification updates, rubblization, stone matrix asphalt best management practices, electrical plant inspection, partnering, MSCR test, and best management practices for quality projects . Thank you everyone who attended!
