Samenvatting
The main purpose of this paper is to describe the construction procedures used in incorporating flax straw into the subgrade on Highway 19 and share Saskatchewan Department of Highways and Transportation experience in using this agricultural waste by-product as a subgrade strengthening material. The field test results and performance findings are also discussed. The research methodology used considers three main elements: 1. pre-construction investigation including road surface conditions, preliminary field and lab tests; 2. construction procedures used in installing the flax straw test sections; and 3. discussion of post-construction field and lab test results.
