What is it?

Greenroads is a rating system designed to distinguish more 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.

How does it help?

More sustainable roadways. This means less impact on the environment, lower life cycle costs/impacts and more positive societal outcomes.

Greenroads is a project-oriented system.

It does not deal with planning and it does not deal with operations.

slide12
There are a lot of definitions for “sustainable” out there. This is how Greenroads defines sustainability.

Sustainability is a system characteristic which refers to the system’s capacity to support natural laws and human values.

slide13
There are a lot of definitions for “sustainable” out there. This is how Greenroads defines sustainability.

Sustainability is a system characteristic which refers to the system’s capacity to support natural laws and human values.

  • Natural laws = Ecology
    • Rule: Don’t break the earth
    • How we do this:
      • Do not take stuff out of the earth faster than it will go back in.
      • Do not produce stuff (e.g., pollution) faster than it can be broken down and integrated back into nature.
      • Do not diminish nature’s productivity or diversity or we will affect nature’s ability to process stuff that we create or use.

There are a lot of definitions for “sustainable” out there. This is how Greenroads defines sustainability.

Sustainability is a system characteristic which refers to the system’s capacity to support natural laws and human values.

  • Natural laws = Ecology
    • Rule: Don’t break the earth
  • Human values = equity and economy
    • Equity rule: Seek quality of life for all
    • Economy rule: Manage resources wisely
    • Resources = human, natural, manufactured and financial capital

Sustainability is a system characteristic which refers to the system’s capacity to support natural laws and human values.

  • Sustainability should be:
    • Measured
    • Judged
    • Managed
    • Improved
sustainability should also include 4 more items
Sustainability should also include 4 more items.

7 total components:

ecology, equity, economic

extent, expectations, experience, exposure

  • Defining “sustainable” for your project

1. Extent: how long do you want it to last?

2. Expectations: What are the performance expectations?

  • Making “sustainability” work

3. Experience: Need technical expertise to develop solutions

4. Exposure: Education and public awareness

institutional awareness of environmental concerns can have greater impact than just a project focus

  • There are a number of existing programs:
  • Internal company programs
  • NAPA Diamond Achievement Awards
  • NRMCA Environmental Excellence Awards
  • NSSGA Environmental Eagle awards
  • Many others

ISO 14001:2004 is a means for documenting institutional environmental procedures. The U.S. and North America could be doing better.

Percent Share of ISO 14001Certification By Region

  • 78,000 companies certified worldwide
  • 80% are in Europe and Far East
  • 5.94% in North America
    • 5,585 in the U.S.
    • 1,636 in Canada
  • Of the 39 industry sectors:
    • Construction: 11.5% (2nd)
    • Engineering services: 2.26% (13th)
  • Some U.S. examples
    • Massport, MA
    • Vulcan Materials, Irwindale, CA
    • NC Division of Pollution Prevention and Environmental Assistance

Environmental Management System 2 Credits

The prime contractor, primary designer, or owner shall be ISO 14001:2004 certified.

There are programs in the US that are somewhat equivalent to ISO 14001 certification (e.g., Wisconsin HMA Environmental Leadership Award). They typically apply to HMA, RMC or cement plants but could also be extended to construction operations.

highway safety is a top priority in transportation
Highway safety is a top priority in transportation.

“…among the most compelling public health issues of our time.”

AASHTO: Transportation: Invest in our Future

“Safety is out top priority…”

acting FHWA administrator Jim Ray, 7/25/08

“…road traffic injuries (pose) a global public health crisis requiring urgent national and international action.”

A road safety audit is a formal, independent and documented review that can be used to improve roadway safety.
  • Cost
  • $1,000 - $8,000 depending on size
  • Benefit/cost ratios
  • 2:1 to 242:1
  • First year rate of return: 146%
  • More data?
  • UK is now monitoring results 1 and 3 years after implementation

Example AE Credit

Roadway Safety Audit 1 Credit

Conduct a road safety audit (RSA) or road safety audit review (RSAR), whichever is appropriate, on the roadway(s) involved in the project. Adopt recommendations as practical.

Guidelines for RSA, RSAR and the audit process are contained in FHWA Road Safety Audit Guidelines, FHWA-SA-06-06, 2006. Research surrounding RSA is summarized in NCHRP Synthesis 336: Road Safety Audits.

We have done well recycling hot mix asphalt and portland cement concrete as part of road construction.

Recycled Content 1-4 points

One point: Use recycled content to a minimum of 20% in the HMA/PCC and 40% of the total material if base course, fill, or structures are included in the project.

Two points: Use recycled content to a minimum of 30% in the HMA/PCC and 50% of the total material if base course, fill, or structures are included in the project.

Three points: Use recycled content to a minimum of 40% in the HMA/PCC and 60% of the total material if base course, fill, or structures are included in the project.

Four points: Use recycled content to a minimum of 50% in the HMA/PCC and 70% of the total material if base course, fill, or structures are included in the project.

Most of the energy involved in HMA pavements comes from plant production, so target this for maximum effect.

Warm Mix Asphalt 2 Credits

Reduce the mixing temperature of hot mix asphalt by a minimum of 50oF from that recommended as the mixing temperature by the asphalt binder supplier.

Mixing temperature shall be measured as the temperature of the mixture as it exits the mixing drum (for drum plants) or pugmill (for batch plants). This reduced temperature mix must comprise a minimum of 50% of the total project pavement surfacing by weight to earn this credit.
