Abstract
Subject of the invention is a method to measure the compaction properties of soil and other similar masses. A mass specimen is placed in a cylinder. The mass specimen is then pressed with standard pressure between an upper platen and a lower platen, and the height of the specimen is measured. Also subject of the invention is a device to measure the compaction properties of soil and other similar masses. Characteristic to the method and apparatus according to the invention is the fact that there is a specimen cylinder (2) attached to the frame (1) to be rotated mainly with respect to its central axis.
Claims13
A method for measuring the compaction properties of a specimen of soil and other masses of similar kind utilizing a cylinder with a central axis, an upper platen, and a lower platen, the method comprising the steps of:
- placing a mass specimen in said cylinder;
- rotating said cylinder and mass specimen about said cylinder's central axis that is inclined with respect to said upper platen and said lower platen;
- pressing said mass specimen between said upper platen and said lower platen using standard pressure thus providing deformations that increases the density the mass specimen;
- and
- measuring the height of said mass specimen as an indicator of the compaction property of the mass specimen.
A device for measuring compaction properties of masses of a specimen of soil and other masses of similar kind, comprising:
- a frame, a specimen cylinder, a pressing device, an upper platen and a lower platen;
- the upper platen and the lower platen are adapted to be pressed with a pressing device against the specimen;
- and
- wherein the specimen cylinder has a central axis which is angled relative to a vertical axis, wherein the upper and lower platens are inclined with respect to the central axis of the specimen cylinder, and wherein the specimen cylinder is attached to the frame to be rotated mainly with respect to its central axis.
