- Abstract:
- The title of Section 204 has been changed to “Section 204 Flowable Fill”, as the use and installation requirements for Lightweight Concrete Fill have been added to the Section which previously only contained the requirements for Controlled Low Strength Material (CLSM). Lightweight Concrete Fill is an engineered geotechnical material with a unique strength / density relationship which can be used to reduce loads on soft foundation soils, buried structures, or against retaining walls. Lightweight Concrete Fill consists of a Portland cement matrix containing uniformly distributed, non-interconnected air voids introduced by a foaming agent. The flowability and cementitious properties of this material provide a product that is self leveling and does not require compaction. Additives can be introduced to achieve grades of as much as 3% ± from the horizontal. The Geotechnical Engineering Bureau (GEB) provides earthwork and foundation engineering services for the design and construction of Departmental projects statewide. When subsurface explorations reveal that a project’s underlying soils are soft or unstable, the GEB may utilize specialized treatment options to allow completion of the desired final product. Lightweight Concrete Fill is one such option. It is a lightweight fill used to reduce vertical stresses beneath embankments, or to reduce lateral stresses on retaining walls, abutments or foundations.
