13
Highway Pavements RT
  • Critical issues
  • From 1970 to 1998 average daily traffic volume
    has increased 130. Average daily loading has
    increased 580.
  • Average freight loading is currently increasing
    at 2.7 per year.

14
Highway Pavements RT
  • Critical issues
  • Just in time delivery has increased from 10 in
    1990 to over 60 in 2000.
  • Of every dollar invested in highways more than 50
    cent goes to pavements.

15
Highway Pavements RT
  • Critical issues
  • Earmarking of pavement RT funding has directed
    significant efforts to special interest
    activities.
  • Growing need to identify and understand factors
    that contribute to pavement performance and to
    predict performance.

16
Highway Pavements RT
  • Priority Areas
  • Designs and materials for longer life more
    cost-effective pavements
  • Less disruptive construction and maintenance
    technologies and technologies to reduce user
    delay while maintaining service and securing work
    zone safety.

17
Highway Pavements RT
  • Priority Areas
  • Safer more environmental friendly pavements
  • Education, communication, and job training.
  • Promotion and delivery of innovation

18
Designs Materials for Longer-lived More
Cost-effective Pavements.
  • Research Needs
  • Accurate prediction of pavement performance over
    extended periods under severe loading conditions.
  • Reliable data on pavement performance.
  • Equipment to accurately assess pavement condition
    at highway speed.
  • Understanding the interaction of design,
    construction, materials, traffic and environment.

19
Safer, Environmental Friendly Pavements
  • Research Needs
  • Pavement surface properties noise, friction,
    stability/durability, visibility and aesthetics.
  • Understanding vehicle/pavement interaction
    noise, handling and traction.
  • Impacts to adjoining business and communities.

20
Promotion and Delivery of Innovation
  • Research Needs
  • Move results of research into practice as soon as
    possible.

    a longer service life than traditionally expected
    while reducing life cycle costs.

26
Effective Management of Pavement Assets
  • Building Blocks
  • Identify data needs (climate, traffic, as-build
    design and materials)
  • Data collection methods (quality, consistency,
    and standardization)
  • Integration and development of new data
    collection tools
