12th ISAP Conference on Asphalt
Dragos Andrei, Ph.D., P.E.
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.
Pavement materials and
practices involve a mix of
sustainable and non-

STATUS AND PLANS
Greenup 1.0 for Windows available for evaluation purposes only at
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
As materials and technologies “green up,” the application should be
periodically update to reflect significant improvements.
Provide practitioners with simple, convenient tool to evaluate
sustainability aspects of pavement design/rehabilitation
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.
