Title: LIGHTWEIGHT FOAMED CONCRETE FILL
Accession Number: 00647247
Record Type: Component
Availability: Find a library where document is available Abstract: Since 1981 the New York State Department of Transportation (NYSDOT) has used lightweight foamed concrete fill (LFCF) to reduce loads on clayey and organic soils that are weak and highly compressible. LFCF is also used to reduce lateral loads on abutments and retaining walls. To date, it has been used successfully in place of conventional fill on seven projects involving 12 placement areas: 10 permanent bridges, 1 temporary detour bridge, and 1 set of existing retaining walls. LFCF, typical applications, and placement, as well as quality assurance and testing, are described. NYSDOT specifications, design considerations, and a comparison with another lightweight fill are discussed, and NYSDOT's experiences with LFCF and its performance are summarized.
