Pavement and Materials Partnering Committee
About Us
(Please email pmpc@dot.ca.gov for inquiries)
The PMPC was established in 2018 as a collaborative effort by the California Department of Transportation (Caltrans) with the construction industry (Industry) to review and propose improvements to Caltrans roadway construction specifications, and test methods for aggregate, asphalt, and concrete materials.
The goal of the PMPC is to operate efficiently and deliver work products in a timely manner by. These work products typically involve improvements to construction contract standards, encompassing construction methods, specifications, and testing methods.

Asphalt Task Group (ATG)
The Asphalt Task Group (ATG) is a technical committee under the Pavement and Materials Partnering Committee (PMPC). It brings together representatives from Caltrans, the construction Industry, academia, and other stakeholders to collaborate and advance asphalt pavement specifications, construction methods, and testing procedures. The ATG serves as a forum to evaluate research needs, develop and update specifications and test methods, investigate innovative solutions, and address challenges related to asphalt materials, construction, performance, and sustainability. Through open collaboration and data-based decision making, the ATG works to improve asphalt pavement quality, resilience, and innovation in support of California’s transportation infrastructure.
Concrete Task Group (CTG)
Within the Pavement & Materials Partnering Committee, the Concrete Task Group (CTG) is the task group dedicated to concrete pavement materials, specifications, test methods, and pilot projects. It brings together the Pavement Program, METS, Construction, industry, academia, and technical experts to collaboratively develop, refine, and implement improvements to concrete pavement and pavement foundation specifications, test methods, and related guidance. CTG serves as the forum where research findings, field performance feedback, and specification updates are vetted before advancing through PMPC for broader adoption, ensuring alignment between specification ownership, materials testing, and construction execution. Its importance lies in reducing risk, preventing siloed decision making, and translating technical innovation into clear, practical statewide standards that directly influence the long term performance and durability of California’s concrete pavement network.
