A description of the proposed Green Up pavement rehabilitation decision tool.

1. GREEN UP
Dragos Andrei, Ph.D., P.E.
CalAPA 2018 Fall
Conference

2. CONCEPT
Designers are open to include sustainable rehabilitation strategies
but they have limited knowledge, time, and access to relevant
resources and contacts
Comprehensive solutions are available but require considerable time
and financial commitments (e.g. LEED, Greenroads)
Green Up is meant to provide a quick way to visually compare
rehabilitation alternatives, learn what options are available, and
access links to industry web sites and contacts
Green Up = decision tool + educational portal + link to industry

3. SCOPE
Develop the framework for a pavement rehabilitation strategy
selection tool that will be available online, for free.
Designers will have the ability to explore and compare various
strategies in terms of:
- responsible use of materials
- global warming potential
- surface characteristics (permeable, cool, quiet)
- life
Include a strong educational component: information + links to
relevant resources

10. II. GLOBAL WARMING POTENTIAL
Use amount of CO2eq from Environmental Product Declarations (EPD)
or
Predicted amount of CO2eq from predictive models based on EPD data
Life Cycle: “cradle to gate” only at this time
Include (learn about) carbon offsets or credits

11. III. SURFACE PROPERTIES
PERMEABLE Credit for Porous Asphalt/Pervious Concrete/Permeable
Pavers
COOL Credit for high Solar Reflectance Index (SRI)
QUIET Credit for low noise levels
Options:
YES NO N/A

12. IV. LIFE EXTENSION
Designers should strive for longer life within budgetary constraints
Links to pavement performance prediction resources will be provided
Links to life cycle cost analysis resources will be provided
Life
Extenstion:
Temporary
< 10 years
Typical
> 10 years
New Design
> 20 years
Long Life
> 40 years
Perpetual
> 70 years
