Appendix C (continued): Skill Set Reporting Forms

Long Life Pavement/Maintenance

Idea (Short Name) IDEA (Detailed Description) Implementation Details (Barriers, Skill Set Coordination, etc.)
Long life pavement (mainline).
  • Design pavements for the longest life possible in harmony with the structures along mainline. Strongly consider concrete solutions (DJCP with widened slabs), due to local performance history, lower sensitivity to base instability, and rehabilitation potential.
  • Use M-E Pavement Design (NCHRP 1-37A) procedures for final design (move away from outdated empirical design methods toward mechanistic approach).
Pavement drainage.
  • Ensure that water effects are considered with properly designed and constructed drainage system, particularly in depressed sections (critical issue).
  • Ensure proper execution by use of video inspection and performance specifications. Design and construct drainage feature to be less susceptible to damage from maintenance work or errant vehicles.
Construction controls.
  • Ensure that quality and speed are attained by employing the latest available tools and techniques.
  • Require use of maturity methods (for strength, to accelerate construction, and curing control), nondestructive dowel bar locator.
Mixture considerations.
  • To provide a mixture that is producible while meeting the durability requirements of a long life pavement.
  • Air void specification detailing required spacing factor (AVA), optimized aggregate gradation, and require use of limestone aggregates.
Performance specifications.
  • Employ performance specifications where possible in a variety of areas to maximize potential for high quality.
Performance specification should be implemented in the following areas, if possible:
  • Drainage.
  • Smoothness.
  • Dowel alignment.
  • Maturity (strength and temp management).
  • Curing.
  • Friction?
  • Noise?
Incentives.
  • Re-examine the use of incentives/disincentives. Also ensure that the magnitude of the incentives reflect the magnitude of the project.
  • Attempt to correlate properties to performance to develop appropriate incentives (i.e., provide incentives that motivate contractors to improve the quality).
Single mainline paving contract.
  • If single contract not possible, then minimize number of paving contracts as much as possible. Makes an onsite plant more feasible, reduces coordination efforts, improves uniformity, and potentially speeds construction and reduces cost.
  • An onsite plant will speed construction, minimize congestion, and encourage innovation.
  • Barrier: Current system encourages multiple small contractors to spread the work around.
Construction sequencing/schedule.
  • Sequence and schedule paving to minimize conflicts with other work, and to maximize speed of paving.
  • Finish mainline bridges prior to start of paving. Avoid contractors obstructing each others' work in contract documents. Avoid scheduling paving during winter months to maximize speed of construction.
