Compacted Low strength material (CLSM) made with material such as fly ash and recycled aggregates is used as filler at city infrastructure canals without compaction need. Experimental small specimens and large canals were casted with this concrete and tested to give several results. Test results of compression strengths on 12 different designs shows that this concrete with high workability and w/c ratio over 2 can be replaced with low compacted filled soils and can reduce asphalt settlement over city pavements. Large CLSM canals inside and outside of laboratory tolerated concentrated loads from 3.5 to 7 ton about standard 45-ton Truck (at Bridge and pavement design codes) with low settlement after two months and showed acceptable structural behavior.
