SOILCEMENT 1. 2.3 1.1cement shall consist of soil, portland cement, and water proportioned, mixed, placed, compacted, and cured in accordance with these specifications and shall conform to the lines, grades, thicknesses, and typical crosssections shown in the plans.
The cementtreated subgrade CTS shall not be mixed when the subgrade material is frozen or raining to the extent that moisture content cannot be controlled. The CTS shall not be mixed or compacted if the temperature of the cement or soil is below 35 F measured 3inches below the surface of the CTS.
Construction of Cement Treated Subgrade The DesignBuild Team shall construct the soil cement subgrade as specified in section 542 of the North Carolina Department of Transportation 2006 Standard Specifications for Roads and
Compactors When compacting cement treated sections greater than eight 8 inches, a sheepsfoot type compactor capable of compacting the entire section to the project specification shall be used. 3.0 CONSTRUCTION 3.1 The contractor shall use the soil designated by the engineer and the cement
A cementmodified soil CMS is a soil material that has been treated with a relatively small proportion of portland cement less cement than is required to produce hardened soilcement. The objective of the treatment is to amend undesirable properties of problem soils or substandard materials so that they are suitable for use in construction.
Section 301SoilCement Construction Page 3 Mix and place cementtreated base or subbase only when the weather permits the course to be finished without interruption in the time specified. Mix and place materials only when the moisture content of the soil to be used in the mixture meets the limits specified in this Subsection.
Jose N. Gomez S., Soil Cement StabilizationMix Design, Control and Results During Construction. All soil cement cylinders made from the asphalt blended base material have an observed maximum dry density of approximately 127 pcf and an observed optimum moisture content of approximately 5.6. These results are similar to those obtained in the lab
Soil cement is a composite material of pulverized soil, Portland cement, and water which forms a durable structural material. It has been used throughout the world to enhance the strength characteristics of bases for roadways, parking l ots, and buildings. When Portland cement is blended with water and soil and
ii Abstract Cementtreated base CTB is a mixedinplace or centralplantproduced material consisting of soilaggregate, cement, and water that creates a strong and durable stabilized roadway base. This guide to CTB discusses its applications, benefits, design, construction, testing, and performance.
Construction Specification 29Soil Cement. 292 210VINEH, January 2009 3. Operations of pits or stockpiles of soil material All work required in the opening and operation of borrow areas or stockpiles shall be performed by the contractor.
Cementtreated base CTB is an intimate mixture of aggregate material andor granular soils combined with measured amounts of portland cement and water that hardens after compaction and curing to form a durable paving material. A bituminous or portland cement concrete wearing course is placed on the CTB to complete the pavement structure.
Nontreated, 5, and 10 cement treated soils displayed ductile, planar, and splitting type of failure, respectively. For 10 cement treated soils pore pressures rose rapidly to confining pressure s resulting in zero effective confining pressure at failure.
Soilcement, also referred to as cementmodified soil and cementtreated aggregate base, is a dense, highly compacted mixture of soil or roadway material, portland cement and water. Soil material can be almost any combination of sand, silt, clay, gravel or crushed stone.
