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.
