Innovation & Research

The PRRC has full capability of conducting practical research and development for the enhancement of all recycling and reclaiming fields. It is not the intent of the Center to “reinvent the wheel” with respect to research that has already been conducted. Instead the PRRC proposes to help Industry and agencies alike to provide a sustainable, cost effective pavement for the “wheel” to ride upon. The PRRC’s goal is to fill the gap in research and innovation as recycling and reclaiming technologies evolve. Some of the services that will be offered include:

  • Contracted Research
  • Proposed project and technology applicability determinations
  • Improve the performance of recycling and reclaiming projects through specification and guide enhancements
  • Project performance monitoring and long term evaluation

Currently Contracted Research

  • In August 2010 the Center signed a $1,000,000 agreement with Caltrans to provide technical assistance, research and training in the area of pavement recycling and reclaiming. Currently the Center is performing a literature review on the usage of high percent reclaimed asphalt pavement (RAP) in hot mix asphalt concrete.
  • In early 2011, an agreement was signed with the Asphalt Recycling and Reclaiming Association (ARRA) to assist with suggested guidelines, best practices and education programs.
  • Some ARRA members have engaged under separate contract with the Center for an evaluation of the performance and life cycle cost of CIR with a thin overlay.

Defined Research Needs Requiring Funding Sources

  • Better lab testing equipment and procedures to allow for the increase of structural values of recycled pavements
  • QC test methods for the cohesion/adhesion of bituminous CIR and FDR
  • More as determined necessary
