Sustainability Rating Systems
• What are they?
Typically, points based rating system designed
to assess the sustainability of
pavements/infrastructure.
• Goal:
To provide an assessment of the sustainability
of pavement/infrastructure designs and
construction for the purpose of promoting
environmental “Best Practices”.

Need:
Growing demand for designers to implement
sustainable initiatives into public
infrastructure projects.
Challenge:
To develop a System that can identify the
benefits and project impacts, compare
options in a balanced, transparent manner
and quantify the benefits.
Methodology: Implement a sustainability rating system, SRS
How to Identify Sustainable

GreenPave Overview
Applicability:
Applicable to all designs of flexible and rigid pavement
structures.
Background:
GreenPave is primarily based on the Greenroads and
GreenLITES rating systems, customized for Ontario. The
LEED certification program were also referenced.
Note: The main difference between GreenPave and
many of the other systems is that GreenPave focuses
specifically on the pavement component rather than
the entire road.

Integration of SRS into PMS
• Sustainability principles need to be integrated
into all engineering decision making
processes and management systems
• SRS can be readily incorporated using Excel-
based decision support tools
• Tools will ensure all viable sustainability
opportunities are considered
• Sustainability profiles in graphical form can
be provided beside LCC data

Summary
We will better achieve our sustainable pavement goals through:
Building on current industry/agency partnerships in the development of improved specifications and design/construction procedures
Encouraging continued innovation by our pavement preservation and rehabilitation contractors
Supporting dedicated research programs to advance sustainable technologies
Increasing technology transfer to accelerate adoption of sustainable pavement concepts
![Page 33: Integration of Sustainability Rating Tools in Contemporary … · 2015-06-04 · Life Cycle Cost (LCC)1 ... maintenance and effectiveness. Integration of SRS into PMS •Sustainability](https://reader033.vdocument.in/reader033/viewer/2022050118/5f4ec607f100e85e4d1a2a26/html5/thumbnails/33.jpg)
Conclusions
• The GreenPave and GoldSET Rating Systems have
been well received and are endorsed as viable
sustainability assessment tools for pavements.
• Ultimately, the goal of GreenPave and GoldSET is
to enhance the sustainability of transportation
infrastructure through designing, promoting and
selecting the most economical and environmental-
friendly pavement treatment alternatives.

Conclusions
• There is an increased focus on sustainable asset preservation and rehabilitation, both at the state/provincial and municipal levels
• “Sustainable” pavement preservation and rehabilitation treatments applied at the right time can significantly extend pavement life and result in improved network performance over time
• Implementation of sustainable AM principles and performance measures are critical to addressing infrastructure investment requirements and environmental stewardship over the long-term
