STANDARD COMPACTION TEST (Standard Proctor Test Apparatus):

AS PER IS: 2720, (Part-Vll)

Introduction:

Compaction: When Compaction of soil in the field is done using rolling machines, it is important to know O.M.C. and M.D.D. values. Standard Compaction test is used to determine in laboratory Optimum Moisture Contents (O.M.C.) and Maximum Dry Density (M.D.D.) of soils, which represents field samples. Compacted soils have increasing use in embankment of dams, highways, railways etc.

In recent years in order to meet current heavy traffic on runways and highways, heavy duty field compacting equipment has come into use and in view of reproducing greater densities, heavy compaction tests using heavy compaction apparatus have been developed.

General Description and Specifications: The apparatus consists one each of

• Compaction Mould: Made of Mild steel or Gun Metal, 100± 0.1 mm I.D. x 127.3 ± 0.1 mm mm height x 1000 cc volume, complete with collar and base plate.
• Rammer 2.6 kg x 310 mm controlled fall. Weight of rammer is 2.6 Kg, diameter is 50 mm, chrome plated.
