Accurate Subgrade Soil Evaluation

The Field CBR Equipment ensures precise measurement of soil strength, which is crucial for assessing subgrade suitability in civil engineering projects. With a 0.01 mm dial graduation and 100% accuracy, it enables reliable analysis for pavement and foundation designs. The robust construction and compliance with recognized standards make it a preferred choice for soil testing laboratories.

Manual Operation for Versatile Field Use

Designed with manual and mechanical operations, the Field CBR-01 offers flexibility in environments where power sources are not readily available. Its compact dimensions (approx. 600 x 400 x 1100 mm) and portable design (approx. 48 kg) allow easy transportation and setup at various field locations, ensuring convenience alongside high-performance testing capabilities.

FAQs of Field Cbr Equipment:

Q: How is the Field CBR Equipment used to determine the CBR value of subgrade soil?

A: The Field CBR Equipment determines the CBR value by applying a controlled load using the manual loading plunger onto a soil sample. The penetration of the plunger is measured via the analog dial gauge, and the maximum load applied is recorded. This data is used to compute the soils resistance to penetration, representing its bearing capacity.

Q: What are the main components included in the Field CBR-01 equipment package?

A: The Field CBR-01 includes essential parts such as a loading plunger (50 mm diameter), loading frame, analog dial gauge, proving ring (capacity 50 kN), and a cutting collar (150 mm diameter). These components allow for straightforward setup and accurate measurement of soil bearing properties.

Q: When should the Field CBR Equipment be used during construction projects?

A: This equipment is best used during the preliminary phase of road, pavement, or foundation construction. It helps evaluate the strength of subgrade soil before actual construction begins, ensuring that the chosen site meets required specifications and minimizing risk of structural failure.

Q: Where can the Field CBR Equipment be effectively utilized?

A: The Field CBR Equipment is suitable for both laboratory and field settings. Its manual operation and moderate weight (approx. 48 kg) enable convenient on-site testing as well as controlled laboratory assessments, providing flexibility for civil engineers and soil analysts.

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

A: To conduct a CBR test, prepare a soil sample and place it under the loading plunger. Gradually apply force using the manual loading system and monitor penetration depth with the dial gauge. Record the force required at set penetration intervals. Follow either IS:2720 (Part XVI) or ASTM D1883 procedures for calculation and reporting.

Q: What are the benefits of using the Field CBR-01 equipment?

A: The Field CBR-01 provides highly accurate (100%) results and complies with industry standards. Its durable, enamel-coated steel construction ensures longevity, while the analog display and manual operation make it user-friendly and reliable in varied conditions. Portable design also makes it apt for field deployment.
