• Sustainability is the capacity to endure. In ecology the word describes how biological systems remain diverse and productive over time. For humans it is the potential for long-term maintenance of wellbeing, which in turn depends on the well being of the natural world and the responsible use of natural resources.

16

A little Sustainability History….. • Great Depression and World War II • Post-1950’s "great acceleration” of growth and population, aka the

“Golden age of capitalism” • 1962 American marine biologist Rachel Carson released her

influential book Silent Spring • 1970s concerns with pollution, population, consumerism and the

depletion of finite resources… Is growth obsolete? by American economists William Nordhaus and James Tobin

• 1987 the United Nation's World Commission on Environment and Development report Our Common Future suggests sustainable development was needed…

• Contrast: 1961 almost all countries in the world had the capacity to meet their own demand, but by 2005 the situation has changed and many countries are only able to meet their needs by importing resources from other nations. A move toward more sustainable living emerged…

• 21st century there is heightened awareness…Many new techniques have arisen to help measure and implement sustainability, including Life Cycle Assessment, Cradle to Cradle, Ecological Footprint Analysis, and green building.

17

EPA’s Sustainability Definition

Sustainability means “meeting the needs of the present without compromising the ability of future generations to meet their own needs.”

18

Sustainability – FHWA Definition

• Sustainable Transportation means providing exceptional mobility and access in a manner that meets development needs without compromising the quality of life of future generations.

• A sustainable transportation system is safe, healthy, affordable, renewable, operates fairly and limits emissions and the use of new and nonrenewable resources.

A Pavements Perspective

.

21

Sustainability is HUGE!!! • Pavements are really only a small part of the

main discussion, but…

• What can I (we) do In My (Our) Back Yard???

22

In My (Our) Back Yard

Structural Design

Materials/Mix Design

Production/ Placement

Q. Where can we make this greatest Impact?

Agency/Owner Acceptance

Assessment/ Maintenance/ Preservation

Sustainable Pavement Systems 23

2012 FHWA Pavement Strategies

Environmental Impacts • Develop processes to gather data

• Develop an architecture for assessing

impact…

• Coordinate and collaborate

• Promote GREEN Paving Technologies

24

Understanding Sustainability & Evolving Tools

• Qualifying/Quantifying Sustainability • Life-Cycle Cost Analysis (LCCA) to… • Life-Cycle Assessment (LCA) • Rating/Ranking Systems

25

Sustainability Assessment Terms • Short Term (3 to 5 years)

– Assess impact on new technologies on production – Ex. Rate of Return on Capital Investments vs Benefit

• Functional Term (20 to 40 years)

– LCA Project & Network Level

• Long Term (50 to 100+ years) – Strategic Materials Resources – Ex. Some States will not

meet aggregate needs for the next 25 years…

26

Leadership in Energy and Environmental Design (LEED)

• LEED Green Building Rating System – Developed by the U.S. Green Building Council

– Since inception in 1998, LEED has grown to

encompass more than 14,000 projects in the US and 30 countries covering

27

Please Note: There are Many Rating Systems, and FHWA does not endorse a national rating system.

“Greenroads” Rating System www.greenroads.us

28

FHWA Rating System • In FY2010, FHWA will be developing an online

Sustainable Highways Criteria and Self-Evaluation Tool …

GREEN Paving Technologies

People Driven – Technology Based Solutions

30

Green Paving Technologies

Provides cost effective solutions for reducing our highways’ carbon footprint and preserving natural resources.

– Reduce emissions

– Use of existing, aged highway materials, and recycled materials

– Effective use of locally available marginal materials

31

• Transportation agencies face growing demand for materials – Industry is turning more and more to reclaimed materials as a

quality ingredient in paving mixtures

• There is an urgency towards “GREEN” technologies and sustainable pavements due to innovative technologies and stricter environmental regulations

• The challenge facing highway agencies is using alternative methods, technologies, and materials while maintaining quality, well-performing pavement infrastructure.

Growing Demand, Sustainability, and Maintaining Quality and Performance

32

What technologies are available today?

• GREEN Paving Technologies are market ready – History of successful use

– Guidance is available from various sources

– Improved techniques and technologies
