Cbr Test Of Soil Pdf

Remove the mould from the tank and allow water to drain. 2. Draw the graph between the %age CBR and Dry Density, and find CBR at required degree of compaction. C.B.R Definition 2. Engineering Materials Torsion Test on Iron/Steel Tests on Stones CBR Test Bitumen Penetration Test Los Angeles Abrasion Test Plastic Limit of Soil GeoTextiles Bitumen Civil Engg. After four days, measure the swell reading and find %age swell. Weight of mould compacted specimen. The California Bearing Ratio Test (CBR Test) is a penetration test developed by California State Highway Department (U.S.A.) for evaluating the bearing capacity of subgrade soil for design of flexible pavement.

Test Data Observations & Calculations 5. Draw the graphs between the penetration (in) and penetration load (in) and find the value of CBR. Graphs 5.1 Graph of Penetration vs Loading in CBR Test 5.2 Graph of CBR vs % Percent Compaction Graph 6. The results obtained by these tests are used with the empirical curves to determine the thickness of pavement and its component layers. Take sample for determination of moisture content. Apply the load and note the penetration load values. USES AND SIGNIFICANCE of California Bearing Ratio Test: The CBR test is one of the most commonly used methods to evaluate the strength of a sub grade soil, sub base, and base course material for design of thickness for highways and airfield pavement. This instruction sheet covers the laboratory method for the determination of C.B.R. to that required for the corresponding penetration of a standard material. Tests are carried out on natural or compacted soils in water soaked or un-soaked conditions and the results so obtained are compared with the curves of standard test to have an idea of the soil strength of the subgrade soil. Definition of CBR: It is the ratio of force per unit area required to penetrate a soil mass with standard circular piston at the rate of 1.25 mm/min. APPARATUS Used: Mould Steel Cutting collar Spacer Disc Surcharge weight Dial gauges IS Sieves Penetration Plunger Loading Machine Miscellaneous Apparatus CBR Graphs Significance of CBR Concrete tests Bitumen tests Civil Lab Tests Transportation Engineering Road Structure Cross Section Raised Pavement Markers Highway Maintenance Bearing Capacity 3. Place the mold in the soaking tank for four days (ignore this step in case of unsoaked CBR. CBR test Data - Observations & Calculations 5. Back to top 4.
