PR-3: Lifecycle Inventory

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 2007.

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.)
