Since the advent of geosyntetic fabrics, such as geotextiles and geogrids, use of logs for soil reinforcement has virtually disappeared. Less than 10 years ago I recommended it for an embankment on very soft, swampy soil, using the cut down swamp trees as reinforcement along the border of the embankment. In spite of the careless construction, with logs randomly placed, not orthogonally to the border and tied together as should have been done, only about 20% of the 3-m high, 500-m long reinforced slope failed, proving that somehow the reinforcement worked. But I doubt that even in such cases where logs are available, it is a more economical solution than the geosyntetic one, due to the intense handwork required.

Subject: Corduroy Roads - Any Recent Uses?
Is anyone aware of a recent use (last 50 years or so) of the Corduroy Road principle used on a modern topped road? I have a fairly high traffic 2-lane asphalt road located in a rather saturated area. It's in poor condition and construction equipment has proceeded to rut it out further as the base stays so wet. In discussion, a corduroy road was suggested, but I only find references of application from more than 50 years ago (some of which did include stone & asphalt). Thoughts?

Corduroy road Corduroy road In war, corduroy roads are often used as an emergency measure where poor quality roads have been damaged by the large numbers of vehicles or troops that have passed over them. Seen here are Germans in Yugoslavia in 1944. |
