Asphalt + Innovation

Smart and Sustainable Asphalt Mixture and Design

MAPIL is designed and staffed to support local, state, and federal asphalt paving and design research and time-sensitive mix testing. We comply with established American Association of State Highway and Transportation Officials (AASHTO) and ASTM International standards to provide the highest quality mix design and mix testing services available.

Mix Design

Balanced Designs

Using the most advanced equipment and traditional volumetrics, supplemented with plus cracking and rutting technologies, MAPIL is able to create new balanced, green and smart mix designs to suit your needs.

Green Designs

Our lab constantly strives to develop sustainable mixes, maximize the use of recycled materials, reduce costs, and increase efficiency while lessening environmental impact as much as possible.

Mix designs include:
  • RAP – Recycled asphalt pavement
  • RAS – Recycled asphalt shingles
  • WMA – Warm Mix Asphalt
  • Rejuvenator
  • GTR

Smart Mix Designs

Research and innovation in smart technologies is the future of development in the transportation surfaces industry.

Truly smart solutions seek to minimize the varying challenges of smart mix design. Striving instead to alleviate the issues associated with the installation of sensors, wires, photovoltaics or other electronics into new or existing pavements.

MAPIL creates binder and aggregate mixes using new applications, materials and technologies that integrate with traditional transportation surfaces.

MAPIL collaborates with institutions such as Michigan State, St. Louis University, to develop new technologies, including battery-free and wireless sensors, which can be introduced into the existing infrastructures of developing smart cities.

Mix Testing

MAPIL mix testing is done in house, under closed conditions and confirmed in the field. Our lab provides unbiased, highly refined, rigorous mix evaluation on a spectrum of performance parameters. Including:

  • Cracking and Rutting
  • Moisture Susceptibility
  • Flexural Fatigue
  • Fracture Behavior
  • Binder Content
  • Theoretical Maximum Specific Gravity
  • Bulk Specific Gravity
  • Flash Point
  • Mixture Characterization and Absolute Viscosity Tests

Binder Testing

MAPIL binder test results can indicate the suitability of a binder grade for a particular asphalt paving mixture.

Asphalt binder content directly affects mixture performance in terms of:

  • Pressure Aging Vessel (PAV)
  • Grading/verifying Performance Grade
  • Rolling Thin Film Oven (RTFO)
  • Bending Beam Rheometer (BBR)
  • Dynamic Shear Rheometer (DSR)
  • Viscosity using Rotary Viscometer (RV)
  • Multiple Stress Creep and Recovery (MSCR)
  • Continuous Grading for PG binders

Aggregate Testing

MAPIL tests aggregate materials to directly predict pavement quality.

Particle size and distribution,or gradation, of an aggregate is one of the most influential characteristics in determining how a mix will perform in the field.

How Municipalities Can Utilize MAPIL

Put us to work in your community.

The Missouri Asphalt Paving and Innovation Lab consults with communities across the country and throughout the world to develop more environmentally friendly and economical solutions to transportation materials problems. From modeling to design and field testing to in-lab analysis, we work with municipalities of all sizes to ensure their infrastructure needs are met not only now but in the future.

We work with city and state officials to guarantee all design and testing requirements and standards are met. This enables transportation construction projects to be completed as efficiently and cost effectively as possible — potentially lowering construction times and municipal budgets.
