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
The soil of factory yards, due to its multi-layer structure, is very similar to that of very similar to that of roads. However, its drainage is much more and surface contamination is problematic. The transport logistics are difficult, the speed of movement is reduced and the and the route of the vehicles is variable. All this has as consequences loss of equipment productivity, wood storage problems, high maintenance costs and even negative impacts on the quality of the processed wood. Negative impacts on the quality of the processed wood. Faced with this reality, a team of researchers from FPInnovations' Roads and Infrastructure Group infrastructure group of FPInnovations set out to find solutions.
Abstract
Le sol des cours d’usine, de par sa structure multicouche, ressemble beaucoup à celui des routes. Toutefois, son drainage est beaucoup plus complexe et la contamination de la surface est problématique. La logistique de transport y est difficile, la vitesse de déplacement est réduite et le trajet des véhicules est variable. Le tout a comme conséquences une perte de productivité des équipements, des problèmes d’entreposage du bois, des coûts élevés d’entretien et même des impacts négatifs sur la qualité du bois transformé. C’est devant cette réalité qu’une équipe de chercheurs du groupe Routes et infrastructures de FPInnovations a entrepris de trouver des solutions.

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
The load-bearing capacity of forest roads is often reduced by excess water combined with harsh weather conditions. This decreases the reliability of these roads and has an impact on the cost and access to fiber. In order to overcome this challenge, the construction of feeder roads is one of the most used solutions. This technique involves shaping the road and allowing it to consolidate for a period of time to reduce its moisture content prior to the placement of granular materials. Although this practice is widespread, its effectiveness had never been quantified. With this in mind, FPInnovations, in collaboration with several members of the forest industry, evaluated the technical, financial and functional benefits of this practice.
Abstract
La capacité portante des chemins forestiers est souvent réduite par un excès d’eau associé à des conditions climatiques difficiles. Ceci diminue la fiabilité de ces routes et a un impact sur le coût et l’accès à la fibre. Afin de pallier ce défi, la construction des routes d’avance est l’une des solutions les plus utilisées. Cette technique consiste à faire la mise en forme de la route et à la laisser consolider pendant un certain temps pour diminuer sa teneur en humidité avant la mise en place des matériaux granulaires. Bien que cette pratique soit répandue, son efficacité n’avait jamais été quantifiée. C’est dans cette perspective que FPInnovations, en collaboration avec plusieurs membres de l’industrie forestière, a évalué les avantages techniques, financiers et fonctionnels de cette pratique.

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.
