Caltrans Materials Engineering and Testing Services
California Asphalt Pavement Association EPD Webinar
January 8, 2019

2.  CA and Caltrans Directives to Reach
Sustainability Goals
 Caltrans EPD Implementation Road Map
 Pavement Life Cycle Assessment
 What it means for materials suppliers
Why we’re here today

3.  Data Collection for Benchmarking
 Policy and Legislation:
 Executive Order B-30-15
 California Transportation Plan 2040
 Strategic Management Plan Goal 3 – Sustainability, Livability,
Economy (2015-2020)
 Director’s Policies: 30 - Climate Change and 33 - Sustainability
 CA Assembly Bill 32 (GHG Reduction), 296 (Urban Heat Island),
262/1817 (Buy Clean CA), CA Senate Bill SB-1
Why Is Caltrans Interested in Collecting EPDs?

4. Buy Clean California Act (Public Contract Code § 3500 et seq.)
AB 262 signed October 2017, amended by AB 1817 signed June 2018

8.  Specification language will include EPD requirements for both Buy Clean
California Act (BCCA) and pilot project materials.
 Pilot projects will have LUMP SUM bid item for EPDs, Buy Clean California
Act projects will not.
 Pilot projects only:

How will Caltrans collect EPDs?

9. Visit the METS Website
dot.ca.gov/mets

10. Resources to Navigate EPDs

11. Collecting EPD Information via
dime.dot.ca.gov

12.  Pilots projects will provide knowledge on compliance
and how to obtain and manage EPD data prior to
statewide implementation
 Aggregate, Asphalt Concrete and Concrete EPD Pilot
Projects will start advertising in Spring 2019
 EPD data will be submitted electronically through DIME
 EPDs support Life Cycle Assessment for our
transportation assets
 Go to the METS website to navigate EPDs on
Caltrans projects!
