  • Limited information about the performance of RCA and RAP

built on LSSB.

  • Different mixtures of RCA-RAP
  • Freeze-thaw durability
  • Frost heave-thaw weakening settlement
  • Stiffness
  • No pavement design guideline for pavements built with RCA,

RAP on LSSB.

  • Verify available methods to predict stiffness and strength of

these materials with simple index properties.

OBJECTIVES

1st Goal – Determine the field and laboratory performance

  • FWD, LWD, DCP, Intelligent compaction (IC) data
  • Unsaturated characteristics, index properties

2nd Goal – Develop a method to estimate the stiffness and permeability

  • Percent crushing of recycled aggregates and LSSB
  • Sphericity, angularity, and surface texture of aggregates
  • Gravel, sand, fines content, gravel-to-sand ratio, D10, D30, D50, D60

3rd Goal – Prepare a pavement design and construction specification

  • Performance
  • Cost benefits
  • Life cycle cost

Task 1

Task 1 – Literature Review and Recommendations Conduct a comprehensive literature review on:

  • Current recycling practices of State DOTs from different

climatic regions

  • Previous laboratory and field investigations on the use of

RCA, RAP, and LSSB

  • In depth review on a recently published FHWA report (Edil

2012)

Task 2

Task 2 – Tech Transfer “State of Practice” Prepare a report:

  • To guide local county engineers and state DOTs on how to

apply recommended methods and designs to built highway pavement foundation systems with recycled materials and LSSB.

  • Specific information will be provided about the mixtures of

RCA-RAP-VA, RCA-VA, and LSSB built with different thickness and geosynthetics.

  • CP Tech Center will assist to the research team

Task 5 & 6

Task 5 & 6 – Performance Monitoring and Reporting, and Climatic Effects

Analyze the following data that will be collecting throughout the project

  • FWD, frost heave-thaw settlement, IRI, rutting, surface survey.
  • Temperature, moisture, matric suction, strain.
  • Determine freeze-thaw cycle numbers and its impact on pavement

performance

  • Determine impact of frost heave and thaw settlements on pavement

performance

  • Predict frost/thaw depth
