Description
H-4152
Humboldt CBR Mechanical Test Set
Supports the following standards: ASTM D1883, AASHTO T193
Complete mechanical test set used for CBR testing. Includes a complete complement of test equipment for performing CBR testing. The test set features the H-4156 loading press (load frame), which uses a two-position mechanical jack to provide steady test speeds, as well as rapid travel of the platen for positioning of the sample.
The load frame is supplied with the following accessories:
- (1) H-4454.100, 11,000lbf (48.8kN) calibrated load ring,
- (1) H-4178, 1.95″ (49.5mm) dia. (3 in2 area) penetration piston,
- (1) H-4158.1, 1.000″ x .001, dial indicator and
- (1) H-4178BR dial indicator bracket
The CBR test set includes:
- (1) H-4156: Mechanical loading press
- (4) H-4151: Mold
- (1) H-4153: Spacer disk
- (4) H-4154: Filter screens
- (2) H-4172: Swell plates
- (1) H-4158: Tripod attachment
- (4) H-4175: Surcharge weights
- (4) H-4176: Slotted surcharge weights
- (1) H-4170A: Density hammer
- (1) H-4144.12: Straight edge, 12-inch
- (1) H-4174: Cutting edge
The H-4156 loading press (load frame) uses a two-position mechanical jack to provide steady test speeds, as well as rapid travel of the platen for positioning of the sample.
The Mechanical Compression Machine has been designed to provide a simple and reliable machine to cover a wide range of standard laboratory tests. The loading machine meets the apparatus requirements of ASTM D 1883 and AASHTO T193 allowing a steady rate of penetration load to be applied and a load reading resolution of 10Ibf over a 10,000Ibf (44.5kN) range.
The two-speed jack design of the press allows the following tests to be carried out:
- California Bearing Ratio / Lime Bearing Ratio (CBR/LBR)
- Unconfined Compression on 1.4″ (38mm) diameter sample
- Unconfined Compression on 2.8″ (70mm) diameter sample
- Soil–Cement
- UU (Quick) Tri-axial on 1.4″ (38mm) diameter sample
- UU (Quick) Tri-axial on 2.8″ (70mm) diameter sample
- Marshall Stability and Flow Test
