Geosynthetic reinforcement was evaluated in a road that crossed a muskeg bog. Three options were tested: geogrid, reinforced non-woven geotextile, and corduroy (delimed trees laid side by side). After 1 year, the three road segments provided similar performance. Geosynthetics were less expensive than corduroy if the stems used in the latter approach could have generated a net profit of greater than $/m3. Geosynnthetics are easy to install, require no additional equipment during the installation, and avoid fiber loss.
The principal objective of this test series was to determine the performance from a physical security point of view of reinforced exterior cedar plank doors. The test conditions are described in the report.
Resource extraction companies in western Canada share the same road networks and, as such, frequently must construct road crossings of buried pipelines. Regulations require that construction within the pipeline right-of-way be approved and supervised by the pipeline owner, and be positively located prior to construction. The form of crossing, however, is not well defined and requirements vary between pipeline companies and, even, between construction supervisors working for the same pipeline company. Delays in receiving crossing permits, scheduling difficulties with arranging for pipeline locating and for pipeline representatives to be on site for the construction, and varying and ill- defined construction requirements are challenges for both forestry and oil and gas companies that must cross buried pipelines.
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
Ce guide propose des graphiques simples d’utilisation afin d’aider les utilisateurs dans la conception de routes non revêtues renforcées avec des géosynthétiques. Il permet d’estimer les principaux paramètres d’entrée à travers des procédures
simples et le recours au jugement découlant de l’expérience. Lorsque possible, le recours à des essais en laboratoire est préconisé pour l’obtention de certaines données d’entrée.
