Feb 9, 2017 · select fill or select material is locally defined and generally project specific. It will be different if this for use in a landfill, structures, landscaping or for road construction. For instance, landfill select fill would be lean clay, clayey sand or clayey gravel.
Bearing Capacity of 95% compacted fill 1 - Eng-Tips
Jun 15, 2009 · For a well graded crushed sand and gravel (road base) I've seen as much as 400 kPa used (assuming that there is no underlying softer material within the zone of influence). We've compacted residual clayey silt to silty clay at 95% standard Proctor and obtained an effective friction angle of 32deg.
Engineered Fill Question? - Earthwork/grading engineering - Eng …
Aug 16, 2007 · Engineered fill has much to do with the placement and compaction of the material you are using and not just the material itself. You can use any type of material from granular material to silts and clays for engineered fill provided you have the willingness to place it properly.
Identifying Fill - Soil testing engineering | Eng-Tips
Jun 25, 2012 · Here is my mental list for identification of fill: 1) Presense of organic material below about 5 feet provided its not part of a geologic layer. Peats and lignite are usually easy to associate with a geologic layer. 2) Presence of made-made materials: concrete, slag, garbage, debris, etc. 3) Jumbled structure.
Most suitable fill material - Foundation engineering - Eng-Tips
