Goal
Incorporate energy and emissions information into the decision-making process for
pavement design alternatives.
Requirements
Complete a lifecycle inventory for the final pavement design alternative for the project
using the software tool, PaLATE v2.1 as modified for Greenroads, or approved equal.
Report only results for total energy use and global warming potential (GWP) (in carbon
dioxide equivalent emissions, CO2e) for the final pavement design alternative. The
following input values are required for PaLATE v2.1:
- Total weight and types of virgin materials. This includes aggregates, binders and
base materials. These amounts can be design estimates or constructed totals.
- Total weight and types of recycled materials. PaLATE v2.1 models emissions and
energy for several types of materials.
- Expected transportation distances for all materials. This means distances from
source to production as well as from production to site. Transportation of waste to
disposal is also included.
- Expected construction vehicle types. These include, but are not limited to, pavers,
mixers, hauling vehicles, excavators, rollers, and finishing equipment.
- Estimated design life. Use the same input data as used in the PR-2 Lifecycle Cost
Analysis.
- Scheduled years and expected type of maintenance. Use the same input data as
used in the PR-2 Lifecycle Cost Analysis. This information should also match the
project specifications provided to meet the requirements for PR-9 Pavement
Maintenance Plan and PR-10 Site Maintenance Plan.

Here is PaLATE v2.1 for Excel 2003. The colors are not as appealing because this file was created with 2007 though functionality should be equivalent. (Please consider updating your software if this concerns you.)
