WHAT’S NEW


Changes between versions 2.2 and 2.3


Version 2.3 includes the following enhancements and updates:

  1. Updates to the TRACI measure characterization factors for Global Warming Potential and Acidification Potential.
  2. Updates to the Material data for Ready Mix Concrete Process as well as crushed and natural, coarse and fine aggregates.
  3. Updates to the Equipment data.
  4. Updates to the Pavement Vehicle Interaction (PVI) module.


Changes between versions 2.1 and 2.2


Version 2.2 includes the following enhancements and updates:

  1. Updates to the Canadian manufacturing data for Portland Cement and Portland Lime Cement.
  2. Updates to the Quebec and Ontario Sample Projects and the corresponding Scenario library entries.
  3. Updates to the rigid pavement steel calculator. It is now available from the Roadway design form.
  4. Updates to the Maintenance & Rehabilitation effects calculations
  5. The width value entered for Roundings and Sub-Base roadway design elements is now for the width at the top of the element. Previously the width was defined for the bottom of the element which could result in negative area and volume values could be calculated.


Changes between versions 2.0 and 2.1


Version 2.1 includes the following enhancements and updates:

  1. A brand new name. In effort to more strongly brand the desktop application and the upcoming web application, the name has been changed from to “Pavement LCA” from the “Impact Estimator for Highways”.
  2. Support for US regions (US Average, California, Illinois).
  3. Addition of 8 new sample projects and corresponding Roadway Assembly Library records for US Roadway Designs (US Average, California, Illinois).
  4. Disaaggretation of PVI Effects. In previous versions, the Use Phase Excess Fuel Consumption due to PVI was all lumped into a single bucket. The effects due to Roughness (IRI) and Deflection are now reported separately under the “Use Phase: Excess Fuel Consumption due to PVI” banner.
  5. Estimating steel reinforcement input mass requirements is easier now, thanks to a new spreadsheet resource file.


Changes between versions 1.0 and 2.0


Version 2.0 includes the following enhancements and updates:

  1. TRACI 2.1: The US EPA issued a new version of its TRACI impact characterization methodology in 2012 and this new version of our software now supports the new methods and equivalency measures advocated by the EPA
  2. The Composite Products Library module was overhauled to be more intuitive, and to improve the user experience.
  3. PVI Generation II: The Pavement Vehicle Interaction (PVI) module is based on the latest research and model from the Concrete Sustainability Hub at the Massachusetts Institute of Technology (MIT), "PVI Mechanistic Model Gen II", Dr. Arghavan Louhghalam, in collaboration with Mehdi Akbarian and Prof. Franz-Josef Ulm. December 2013
  4. Addition of 48 new sample projects and corresponding Roadway Assembly Library records for Southern Quebec (Montreal) Roadway Designs.
  5. Addition of 48 new sample projects and corresponding Roadway Assembly Library records for Northern Quebec (Quebec City) Roadway Designs.
  6. Updated purchased electricity profiles on a regional, national and North American inter-tie level
  7. Updated transportation by truck profiles
