Common use of Compaction of Cohesive soil (Soil with clay & slit Clause in Contracts

Compaction of Cohesive soil (Soil with clay & slit. Prior to any compaction, the earth fill layers shall have optimum moisture content as required in clause 6.6.4 of Indian Standard IS 4701-1982. This moisture content shall be fairly uniform throughout the layer. Optimum moisture content (OMC) is the moisture content that corresponds to the laboratory maximum dry density determined in accordance with IS 2720 (Part VII) 1973. In so far as practicable, the moistening of the material shall be performed at the site of excavation (borrow pits) but such moistening shall be supplemented, as required, by sprinkling water (Through fine water spray nozzle) at the site for compaction if necessary, If the moisture content is greater than OMC, the compaction operations shall be delayed until time the earth fill layer has dried to OMC. The moisture content of soils shall be determined in accordance with IS 2720 (Part III) 1982. Compaction shall preferably, be done by 8-10 T vibratory power rollers, non vibratory 8 - 10 Tonne power rollers or sheep foot rollers or other appropriate compaction equipment can also be deployed for compaction, as directed by the Engineer-in-Charge. Manual compaction shall not be allowed. Density tests shall be taken after compaction of each layer. The dry bulk density of the compacted layer shall be not less than 98% of the maximum dry bulk density at optimum moisture content (via 98% of xxxxxxx density). The dry density of soils in fill shall be determined in accordance with IS 2720 (Part XXVIII) 1974 by the sand replacement method or by IS (Part XXIX) 1975 by the core cutter method. The contractor has to ensure compaction to the specified density to the satisfaction of Engineer-in- Charge/his authorized representative. Permission for placement of next layer shall be given only after the earlier layer has been compacted to the specified density. The Engineer-in-Charge or his authorized representative may deploy "Portable electronic/Nuclear gauge density Testers" for rapid on site determination of compaction parameters (Moisture content, in place density and compaction efficiency in terms of % age of xxxxxxx density) to ensure requisite implementation of specification by the contactor.
