Upcoming Research

Stay up to date on new research opportunities supported by CAPRI that aim to improve asphalt pavement performance, safety, and innovation. This section highlights current requests for participation in studies, experimental plans, and collaborative efforts to address pressing industry needs through innovation and implementation.

Request for Proposals: Validation of Short- and Long-Term Oven Aging Lab Procedures

CAPRI invites proposals for a two-part project focused on refining AASHTO R 30 STOA and R 121 LTOA procedures used for asphalt mixtures. The goals of this project include improving consistency, reducing unnecessary steps, and streamlining lab practices.

Submission Deadline: EXTENDED! October 3, 2025
Submit to: Kimmie Lyons (lyonskr@scdot.org)

Researchers may submit proposals for Part 1, Part 2, or both. Each part must be submitted separately with individual project schedules and budgets. Proposals should include technical details (max 10 pages per part), detailed budgets, lab certifications, and staff qualifications.

Key Requirements

  • Technical Proposal Limit: 10 pages (per part, not including resumes or budget docs)

  • Total Budget: $160,000

    • Part 1: not to exceed $64,000

    • Part 2: not to exceed $96,000

  • Expected Duration: 8 months per part

    • Draft deliverables due after 7 months

    • 1-month review by Project Oversight Panel (POP)

    • Recommended start: October 15, 2025

Participation is open to CAPRI members and non-member laboratories with experience testing asphalt mixtures using AASHTO R 30 and R 121. Deliverables include statistical analysis, proposed revisions to AASHTO standards, and presentations at CAPRI meetings and webinars.

Request for Quotes: Examining Specimen Fabrication Variabilities of Balanced Mix Design

* This is an active project, no longer accepting quotes at this time.

CAPRI, in collaboration with the Balanced Mix Design Implementation Working Group, is pleased to release a Request for Quotes (RFQ) for participation in a new research effort titled
"Examining Specimen Fabrication Variabilities of Balanced Mix Design."

This study will investigate how differences in specimen fabrication procedures impact BMD performance measures. It will focus on four areas identified by the BMD Implementation Working Group:

  1. Gmm variability
  2. Oven temperature
  3. Specimen conditioning
  4. HWTT specimen preparation methods

The findings will help the asphalt industry understand where refinement and standardization of procedures are needed to improve the reliability and consistency of BMD performance measures.

Participation is open to CAPRI members and non-member labs with demonstrated experience in compacting and testing IDEAL-CT, IDEAL-RT, and HWTT specimens.

Mandatory Pre-Selection Webinar

Each organization that submits a letter of interest must participate in a webinar to review the details and the Experimental Plan.

Questions from prospective participants will be answered during the webinar. 

📅 The webinar will be held on July 30, 2025, at 1:00 p.m. ET.
