Proposal

“Opportunities to Partner with the Manitoba Trucking Industry on GHG Reduction”• Prepared in response to “Tomorrow Now,

Manitoba’s Green Plan”, a policy document of the Government of Manitoba.

• Co-authored and jointly submitted by the Manitoba Trucking Association and 50by30.

• Submitted April 2014 to Manitoba government

Manitoba Trucking Efficiency Initiative

Proposal - Goal

“double-green”• increase potential for profit in Manitoba trucking

industry by improving efficiency- reduce MegaJoules per tonne-kilometer

• reduce GHG emissions from road freight transportation- in Manitoba

- everywhere Manitoba trucks haul freight

Manitoba Trucking Efficiency Initiative

Proposal - Elements

Regulatory1. Long Vehicle

Combinations

2. New Generation Wide-Base Tires

3. Full Length Boat Tails

Fiscal1. PST exemption on

aftermarket purchases

2. Grants defraying part of the cost of fuel-efficiency technologies

3. Loan guarantees or a PAYS-like program

2. New Generation Wide-Base Tires

goal: to permit NGWBT on select MB roads• all roads classified by MIT as RTAC routes

- http://www.gov.mb.ca/mit/mcd/mcpd/mhcs.html

• by “NGWBT” we mean 445 & 455, or wider

variable effect

fuel efficiency improved

resource consumption reduced

cost to truck owner reduced

waste production reduced

GHG emissions reduced

noise reduced

effect on RTAC roads mixed

• fatigue damage • perhaps somewhat negative

• subgrade rutting • perhaps somewhat negative

• top-down cracking • positive

• near-surface cracking • positive

• hot-mix asphalt rutting • positive

2. New Generation Wide-Base Tires

Effect on pavement, best current knowledge:• Al-Qadi & Wang (2009) “Evaluation of pavement damage

due to new tire designs”• https://apps.ict.illinois.edu/projects/getfile.asp?id=3007

- Wide-base tire causes greater fatigue damage and subgrade rutting than dual-tire assembly

» However, the relative damage ratios between various configurations at the same load decrease as the pavement thickness increases.

- Wide-base tire causes less top-down cracking, “near-surface” cracking, and HMA rutting damage than dual-tire assembly

- Using a wide-base 455 tire results in the least amount of pavement damage for an interstate road, slightly greater damage for a primary road, and more damage for a local road.
