ABSTRACT: For several decades, the City of Victoria was experiencing excessive total and differential settlements in the area around the intersection of Vancouver and View Streets. These settlements had resulted in surface distress to the sidewalk and roadways, as well as damage to underlying utilities. In late 2007 and early 2008, approximately 143m and 215m long roadway sections were reconstructed on Vancouver and View Streets, respectively. A key design element to address the ongoing settlement issues was inclusion of a layer of lightweight cellular concrete as the roadway subbase material. This lightweight material reduced the effective stress on the underlying soil. Since reconstruction, no settlement related maintenance of the roadway or utilities has been required.
RÉSUMÉ: Durant plusieurs décennies, la ville de Victoria fut prise avec des problèmes importants de tassement différentiel dans la zone entourant l'intersection des rues Vancouver et View. Ces tassements ont causé des dommages aux trottoirs et à la chaussée ainsi que des bris aux services publics sous-jacents. À la fin de 2007 et au début de 2008, la chaussée des rues Vancouver et View a été reconstrufondation de chaussée. Ce matériau léger réduisait la contrainte effective sur le sol sous-jacent.
