OVERVIEW

Proctor needles are used for quick evaluation of maximum soil density in the field. Standard Compaction curves showing moisture contents versus densities are drawn in a laboratory using standard compaction method and penetration of the proctor needles is correlated. Proctor needles are also known as Proctor Penetrometer.

Compaction control in the field is exercised by determining the moisture content and dry density. A quick evaluation of this is done by developing curves in the laboratory, showing the relationship between moisture content versus dry density and penetration resistance, using Proctor Needles while conducting the Standard Compaction tests. Consists of a body housing a spring a plunger calibrated to read 0-40 kg x 1 kg and a handle.

SPECIFICATIONS

Technical Specification:-

  • Consist of needle attached to a spring loaded plunger.
  • The stem of which is calibrated to read 0 to 40 kgs in 1 kg division.
  • Long stem is graduated at every 12.5mm to read depth of penetration and for use with needles of larger areas.
  • The small penetration steam is also graduated in 12.5mm division and is used with needles of smaller areas.
  • Needle points one each of 0.25, 0.5, 1.0,1.5,2.0, 3.5, and 6.0 sq.cm.

FEATURES

Two stems are provided, a larger stem and a shorter stem, both graduated at 12.5 mm intervals, to indicate the depth of penetration. The larger stem and the smaller stem are used with needles of larger and smaller areas respectively.
