Supplied with essential moulds, collar, base plate, surcharge weights, and annular weights, the machine supports complete soil CBR testing. The inclusion of a digital or dial gauge display facilitates highly accurate readings, suitable for quality control and research environments in civil engineering.

FAQs of MOTORISED CBR MACHINE:

Q: How is the dual-speed feature beneficial in CBR testing?

A: The machine offers selectable penetration rates of 1.25 mm/min and 1.5 mm/min, allowing users to conduct both standard CBR tests (such as soaked and unsoaked conditions) as per different project specifications or standards, ensuring versatile application in soil mechanics laboratories.

Q: What types of soil specimens can be tested using this motorised CBR machine?

A: This equipment is designed for testing cylindrical soil samples contained in moulds of 150 mm diameter, commonly used for evaluating subgrade strength in road and pavement design.

Q: When should I use the soaking feature during CBR testing?

A: The soaking feature is employed for CBR tests that simulate worst-case moisture conditions. Typically, soaked CBR tests are required when assessing materials that will be exposed to water or high moisture in the field, such as in sub-base layers during monsoon seasons.

Q: Where is this CBR testing machine most commonly used?

A: It is primarily employed in geotechnical, civil engineering, and construction laboratories across India and internationally, especially by manufacturers, suppliers, exporters, and research institutions requiring accurate soil bearing analyses.

Q: What is the process for conducting a CBR test with this automatic machine?

A: The sample is prepared and placed in the mould, the platen and required weights are installed, and the desired penetration rate is selected. The automatic loading frame drives the penetration piston at the set speed while the digital or dial gauge records resistance readings until the desired penetration (up to 100 mm) is achieved.

Q: How does the machine ensure high accuracy during tests?

A: The robust electric motor, precise gear system, and high-quality digital or dial gauge provide measurement accuracy within 1%, ensuring reliable and repeatable results for quality control or research purposes.

Q: What are the main benefits of using an automatic motorised CBR machine?

A: Key benefits include increased testing efficiency, enhanced operational safety due to automatic loading and dual-speed control, robust construction for long-term durability, and adherence to IS:2720 (Part XVI), making it suited for both routine testing and advanced research projects.
