Marshall Stabillity Testing Machine

The test is applicable to hot mix designs using bitumen and aggregates upto a maximum size of 25mm. In this method, the resistance to plastic deformation of cylindrical specimen of bitumenous mixture is measured when the same is loaded at periphery at 5 cm per min.

Flow Table

Flow table is designed for the determination of the flow of the Portland cement concrete.

Compaction Factor Apparatus

It is used to determine the workability of fresh concrete, provided the maximum size of the aggregate does not exceed than 38 mm. The test is useful for concrete mixes of very low workability, where true slump values are not reliable.

Aggregate Impact Tester

Instrument is to determine the Impact Value of Coarse Aggregate.

Los-Angles Abrassion Testing Machine

Used for the determination of the resistance wear by small size coarse aggregate and crushed rock.

Ductility Testing Machine

Used for determining the ductility of asphalted bitumen and fluxed native asphalt cutback bitumen and blown type bitumen. Ductility is defined as distance in centimeter to which a standard briquette of bitumen can be stretched before the thread breaks. The briquette is stretched at a rate of 50 mm / min 2.5 mm / min at a temperature of 27 C 0.5 C.

Compression Testing Machine

It is used for the determination of the compressive strength on cube moulds

Three Gang consolidation Apparatus

It consists of three unit of consolidation apparatus (front loading ) mounted on a single frame. The Flexure Strength Testing are designed to test flexural strength of concrete beams. The design provide maximum rigidity throughout their working range. The load is applied by the downward movement of the piston. A spacer is for testing different size of beams.

Vibrating Table

The vibrating table is used for compacting concrete cubes and cylinders.

Flexure Testing Machine

Flexure Testing Machine is used for testing mortar specimens for flexural strength by single point loading.

Permeability

The apparatus is used for the laboratory determination of permeability of soils using a constant or a variable head. This test is recommended for soils with co-efficient of permeability
