PaveXpress

PAVEXpress-logo-web

The PaveXpress Scoping Tool is a simplified pavement design tool to help engineers and pavement decision-makers analyze pavement structures and create technically sound structural designs. Some of the tool’s key features:

  • Accessible via web and mobile
  • Free, no cost to use
  • Based on AASHTO pavement design equations
  • User-friendly
  • Share, save, and print project designs
  • Interactive help and resource links

 

The Economic Value of Pavement Overlay Alternatives

Capture

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.

SUMMARY OF MINNESOTA RESEARCH FINDINGS MAPA commissioned Erland Lukanen of ERES Consultants to evaluate the performance history of HMA Pavements with Aggregate Base and of Portland Cement Concrete Pavements on the MN/DOT Highway system. The reports on both of these projects are now complete and the results are interesting indeed.

ASPHALT PAVEMENT AT THE STATE FAIR

July 2003, Jill M. Thomas, P.E., MAPA Associate Director

A legacy’s time has come and gone. The half-mile racetrack at the Minnesota State Fair is in the process of removal to make room for more seating at the Grandstand.  The original asphalt racetrack has been in place since 1964 when it replaced the dirt racetrack.

TOTAL ASPHALT VERSUS GRANULAR BASE

June 2003, Richard O. Wolters, P.E., MAPA Executive Director

Total (Full-depth) asphalt pavement structures maintain their strength and deflect less under load. More information on Full-depth asphalt pavement structures can be found in MAPA’s asphalt paving design manual.

PERPETUAL PAVEMENT: TIME HAS COME

May 23, 2003, Richard O. Wolters, P.E. MAPA Executive Director

Total pavement reconstruction, the remove-and-replace option, is rendered virtually obsolete. The only pavement rehabilitation needed would be replacement at about 20-year intervals of the asphalt pavement surface.

REPAIR OF POTHOLES WITH ASPHALT

The performance of a pavement (asphalt or concrete) is directly related to the condition of the base, subgrade and specific material composition of the pavement type on which that pavement is placed.

BLACK AND GREEN: Sustainable Asphalt, Now and Tomorrow

The engineers, scientists, contractors and managers who guide the development of asphalt pavement have made it one of the most environmentally advanced building materials in the world by constantly improving its cost effectiveness and safety. By extending pavement life – by improving materials, designs, or best practices – these professionals reduce the cost to the environment and to the taxpayer.

The asphalt pavement industry and its partners continue to improve the environmental performance of asphalt, already one of the most sustainable pavement materials on earth.
