Green Up
WHAT IS GREEN UP?
 A software application that will produce a color-coded graphic to
illustrate the sustainable and non-sustainable aspects of
pavement rehabilitation strategies.
 An educational tool that will help users learn more about
sustainable pavement materials and practices.
 By design, Green Up was meant to be quick, simple and effective.
The target audience includes primarily those in charge of making
or approving pavement rehabilitation recommendations.
WHY COLORS?
 Pavement materials and
practices involve a mix of
sustainable and non-
sustainable aspects.
 Colors are an easy way to
convey a wealth of information
relatively fast – better than a
numerical index.
 Red = Least Sustainable
 Green = Most Sustainable
LEGEND
 Materials Recycling
 Carbon Footprint
 Permeability
 Heat Island Effect
 Noise
 Life/Cost

STATUS AND PLANS
 Greenup 1.0 for Windows available for evaluation purposes only at
PRRCenter.org/Greenup
 More research needed to set the carbon footprint thresholds.
 Add user costs to Life/Cycle input screen.
 Address any bugs and add better reporting capability.
 In the near future, make Greenup available as a web app/mobile app.
 Contractors could use it in the bidding process.
 Consultants could use it to include sustainability considerations in
their design/rehabilitation recommendations.
 Public agencies could require its use to ensure that consultants
considered several design alternatives and that sustainability is
included.
 As materials and technologies “green up,” the application should be
periodically update to reflect significant improvements.
ULTIMATE GOAL
 Provide practitioners with simple, convenient tool to evaluate
sustainability aspects of pavement design/rehabilitation
strategies.
 Green Up does not replace sustainability rating systems such as
LEED for Neighborhoods, Greenroads, LEED, Invest.
 Educate users about sustainable pavement materials and
practices by providing links to web sites with pertinent information.
 Promote sustainable pavement materials and practices.
