15 This award honors asphalt pavements that were designed and built with outstanding care and exceptional quality. The result is a long-lasting pavement, one that serves the traveling public well, provides true value to the taxpayers, and demonstrates both the convenience and the quality of asphalt pavements. Criteria: 35+ years old 13+ years between overlays (average) No increase > 4" Awards: 117 Pavements 31 States AMERICA RIDES ON US

16 PerRoad Update (v4.4) Implement strain distribution design criteria within PerRoad. Layered elastic analysis with a statistical analysis procedure to estimate stresses & strains within a pavement. Revise PerRoad to include mechanistic design of ALL pavements.

27 What Comes to Mind?

28 Sustainable Development Development that meets the needs of the present without compromising the ability of the future generations to meet their own needs. Our Common Future, 1987

29 Life Cycle Cost Analysis S LCA Life Cycle Assessment

30 Life Cycle Assessment International Organization for Standardization (ISO 2006) addresses the environmental aspects and potential environmental impacts (e.g., use of resources and the environmental consequences of releases) throughout a product s life cycle from raw material acquisition, through production, use, end of life treatment, recycling, and final disposal (i.e., cradle to grave).

31 LCA History 1960 s Energy and raw material concerns Harold Smith (1963): calculate cumulative energy requirements for production of chemical intermediates The Limits of Growth and A Blueprint for Survival Dozen studies to look at costs and environmental impacts Who laid the groundwork?

32 LCA History The Coca Cola Company (1969) developed methods and groundwork for LCA of today Compared different beverage containers to determine environmental releases and required raw materials Other companies followed suit

33 How is an Environmental Product Declaration created? PCR LCA EPD

34 The Family of Acronyms Product Category Rule (PCR): The Framework Set of specific rules, requirements, and guidelines for developing Type III environmental product declarations for one or more product categories (ISO 14025) Life cycle Assessment (LCA): The Process Compilation and evaluation of the inputs, outputs, and potential environmental impacts of a product system throughout its life cycle (ISO 14040) Environmental Product Declaration (EPD): The Declaration Providing quantified environmental data using predetermined parameters and, where relevant, additional environmental information (ISO 14025) Adapted from N. Santero

36 Steps to Getting a Typical EPD 1. Select a program operator 2. Find or commission an LCA study of your product type 3. Develop a PCR committee 4. Make all relevant decisions in committee 5. Have your draft PCR reviewed by at least three experts (and open comment period) 6. Publish corrected PCR 7. Conduct your LCA and draft the EPD 8. Have the EPD reviewed by an expert 9. Publish your reviewed EPD List from Institute for Environmental Research and Education

37 Steps to Getting a Typical EPD 1. Select a program operator 2. Find or commission an LCA study of your product type 3. Develop a PCR committee 4. Make all relevant decisions in committee 5.

41 Before You Start

42 Web-based tool Tool hosted by a third party to ensure confidentiality of data Inexpensive, easy-to-use method to create EPDs Results are calculated and displayed on a printable PDF that can easily be shared with your customer

43 The Authority requires EPDs to be collected by our designbuild contractor for our construction package, called CP4. We have required EPDs from suppliers of concrete and steel products. For other contracts, we have reached out directly to suppliers for EPDs. Margaret Cederoth, AICP LEED AP, Sustainability Manager, California High-Speed Rail Authority

44 Oregon s 2012 Green Chemistry Executive Order led to Green Chemistry Procurement Guidelines for state purchasing activities. This guidance encourages state agencies to use a variety of optional tools (including EPDs) to make more sustainable purchasing decisions. Both Oregon DEQ and Oregon DAS are expected to implement this guidance with more staffing and technical expertise in future state procurement activities. Thus, EPDs may become one of the many tools state agencies use in future procurements to buy more sustainable materials and products.

48 Pollutant Emissions from Asphalt Pavement Mixture (APM) Plants APM plants have engineering controls to minimize pollutant emissions Regulation of APM plants Qualify as minor sources Baghouse required per federal regulations Many states have streamlined permitting procedures as emissions are below de minimis thresholds

49 What s in Dryer Stack Gas?

50 Pollutant Emissions from APM Plants APM plants release small quantities of pollutants, but so do many other sources. Over the course of a year, the following sources release the same level of emissions as an APM plant: Benzene 19 residential woodstoves 1 gasoline filling station Polycyclic aromatic hydrocarbons (PAHs) 176 residential woodstoves Formaldehyde 150 residential fireplaces

51 Impacts of a Typical APM Plant vs. Background: Formaldehyde
