Soil - Compaction

PROCTOR NEEDLE (SPRING TYPE) :
It consists of a body housing a spring, a plunger calibrated to read and a handle. Long stem graduated to indicate the depth of penetration and for use with needles of larger areas Small stem graduated to indicate the depth of penetration and for use with needles of smaller area. Needle point set comprising one each of 0.25, 0.5, 1, 1.5, 2, 3, 5 & 6 sq.cm.
Supplied in a polished wooden case.

PROCTOR NEEDLE (HYDRAULIC TYPE) :
This is identical to the spring type except that the penetration pressure on the needle is conveyed through a hydraulic system to a hydraulic pressure gauge. This system permits a greater control over the rate of penetration because of better visibility of load indication. It consists of bellow housing, casing, casing pipe and pressure gauge. Handle 2 Nos. small stem graduated to indicate the depth of penetration and for use with needles of smaller areas. Complete in a polished wooden case.

PROCTOR COMPACTION APPARATUS :IS 2720 (VIII)
The compaction test apparatus is used for establishing moisture density relationship and for determining optimum moisture content and maximum dry density with standard compactive effort assumed to be equivalent to that normally employed for soil compaction in the field with use of common rolling machines. The values obtained from the compaction test are used for drawing specification for compaction at site and for exercising compaction control in the field.
It consists of :

ABBOT'S COMPACTION APPARATUS
Consists of a steel base, a steel tube and a steel rammer,51/2 lb.weight. The stem of the rammer is graduated in 10ths of an inch

AUTOMATIC COMPACTION APPARATUS
The principle of the machine is the falling by gravity of known weight through pre-determined distance on to a sample which can be either static or revolved automatically thereby setting up a method of compaction by controlled ramming. Two set of rammers are provided , one is the 2.6 kg. X 310 mm fall; and the second is the 4.89 kg. X 450mm fall.

COMPACTION
Compaction control in the field is exercised by determining the moisture content and maximum dry density, quick evaluation of this is done by developing curves in the laboratory showing the relationship between moisture content Vs dry density and penetration resistance using proctor needles while conducting the standard compaction tests. This is further verified within reasonable limits by determining the moisture content by using Rapid Moisture Meters.
