Global Warming Potential – Multi-Project Comparison Graph of Absolute Value by Life Cycle Stage

This graph compares the absolute value of the Global Warming Potential index across selected projects by life cycle stages.

A minimum of two, to a maximum of five, projects may be compared in any given comparison graph. Each project is displayed side-by-side.

Life Cycle Stage Definitions:


Manufacturing:
Includes resource extraction, resource transportation and manufacturing of specific materials, products or roadway components;

Construction:
Includes product/component transportation from the point of manufacture to the construction site and on-site construction activities;

Maintenance:
Includes life cycle maintenance and replacement activities associated with the structure and envelope components based on roadway type, location and a user defined life for the roadway project

Embodied Totals:
Includes life cycle effects due to Manufacturing, Construction adn Maintenance life cycle stages.

Use Phase: Roadway Operating Energy:
Includes life cycle operating energy

Use Phase: Excess Fuel Consumption tue to PVI:
Includes the projected excess fuel consumption due to Pavement Vehicle Interaction.

Roadway "End-of-Life":
Simulates demolition energy and final disposition of the materials incorporated in a roadway at the end of the roadway life. Since roadways are assumed to never really have an end of life scenario, no effects are calculated for demolition.
