We tend to care more

about “green” and

“sustainability” today.

6

In business, sustainability affects

the bottom line.

Why?1. Energy & material costs 2. Because customers care

7

Therefore, corporations care.KPMG International Survey of Corporate Responsibility (2005)

Companies Report Sustainability52% of the top 250 companies of the Fortune 500 issue annual corporate responsibility (sustainability) reports.

Socially, we are driven to improve.

12

We already grade ourselves on sustainable

practices in many different fields.

Other industries, notably the building industry,

have had success promoting sustainability.

The industry has begun to take note.

18

Everyone can make a contribution to

sustainability…including universities and academics.

• Incorporating sustainability into education

• Development and testing

• Verifying function and use

• Systems for use

19

The last decade has produced a relative abundance of

sustainable ideas in transportation and, specifically, in

HMA pavements.

• Context sensitive design

• Certified materials

• Porous pavements

• Quite pavements

• Recycled materials

• Cool pavements

• Non-motorized access

• Reduced congestion

• Improved safety

• Construction waste management

• Life cycle assessment

• Biofuels

• Low-sulfur diesel

• Stormwater treatment

• Visual quality

1. We need some means to organize our

sustainability efforts.

Green Roads is a rating system designed to distinguish high-performance sustainable new or redesigned/rehabilitated roads.

It awards credits for approved sustainable choices/practices and can be used to certify projects based on point value.

21

2. Whether we realize it or not, sustainability is a

strategic direction for agencies, consultants,

contractors and suppliers.
