Abstract
FPInnovations, in cooperation with Alberta Transportation and the Laval University i3C Chair, undertook a review of the starting threshold for initiating winter weight hauling in Alberta. The objective of this project was to conduct an engineering analysis of freezing pavements to determine the minimum frost depth at which log hauling at winter weight premiums (WWP) in Alberta could start without compromising pavement service life. The report describes literature on freezing pavement engineering, Canadian winter weight policies, a controlled trafficking simulation of an instrumented pavement as it was frozen, and subsequent modeling to valiidate results and extrapolate results ot a wider range of pavement structures. It was recommended that the current 1.0 m starting frost depth threshold be reduced to a depth of 700 mm.

Abstract
Forest operations across Canada are encountering increasingly difficult road conditions and more frequent access interruptions related to wet and weak road sections. Resource roads are considered a liability by many forest companies and their business model has been to create the lowest cost, lowest standard, resource road network possible that also will provide tolerable levels of access (i.e., some but not too many failures and hauling disruptions). Increasingly difficult operating conditions and frequent access interruptions, however, drive up costs and threaten the economic sustainability of forest operations. Starting in 2017, FPInnovations has launched a project to provide its members with techniques and strategies that will offer more reliable and strong road sections and reduce overall road costs. A state-of-practice survey of FPInnovations members provided researchers with a comprehensive understanding of conventional means of responding to wet, weak road conditions in Canada. The report summarizes the responses to wet, weak resource road sections that were identified in the state-of-practice survey and provides an overview of the chief causes and related site indicators for wet, weak road conditions. Recommended best practices are provided for a variety of conventional industry responses to wet, weak road sections. These address common misconceptions and knowledge gaps that reduce the effectiveness and increase the overall cost associated with the industry responses. These best practice recommendations were based upon findings from a literature review, product manufacturer information, and from researcher expertise. The report also considers improvements to conventional practices, and advanced solutions that are potentially more effective and economic than the state-of-practice but are not widely exploited by industry. Eleven potential solutions from these two categories were compared and ranked in order of potential. The practice improvements selected for further study were soil compaction, and corduroy and access mats. The advanced solutions selected for further study were geosynthetics that offer both soil reinforcement and enhanced drainage, geocells, and TPCS, a technology to improve truck road-friendliness. Starting in 2021, FPInnovations will initiate field trials and life cycle cost analyses of these technologies.

Abstract
This guide provides users with easy to use charts to assist with the design of geosynthetic-reinforced unpaved roads over weak soils. It permits the estimation of key input parameters through simple procedures and judgment based on experience. Further optimization of designs may however be possible through detailed calculations and lab testing which are encouraged whenever feasible.

Abstract
FPInnovations, with funding from the Canadian Forest Service, is currently investigating the feasibility and form of standardized road - pipeline crossings. FPInnovations and Access Pipeline Inc. jointly conducted a field trial to evaluate the structural responses from heavy vehicle traffic to large (National) pipeline segments buried within a native earth road. This field trial was intended to contribute to the general knowledge of the industry, and more specifically to document the structural performance of large diameter, stiff-walled (pipeline) pipe buried under roads that are crossed by heavy equipment.

Abstract
Canadian regulators utilize the ESAL concept for vehicle impact evaluations and(or) pavement design. Unfortunately, TAC’s ESAL equations do not account for tire size and, consequently, overestimate steering axle impacts when those axles are equipped with widebase steering tires. Many new vehicles proposed for use in Canada feature tridem-drive tractors and heavily loaded steering axles—these heavy loads necessitate the use of widebase steering tires. In order to optimize high efficiency truck configurations in Canada, therefore, accurate estimates of widebase steering tire ESALs are needed. This work describes a methodology to estimate ESALs for widebase steering tires. These ESAL equations were used to justify an increase in steering axle weights for B.C. 9-axle log B-trains.
