CBR Field Test Set, Two-Speed Jack

CBR Field Test Set, Two-Speed Jack

The CBR Field Test Set, Two-Speed Jack is designed for field testing. That's where you need it to be—out in the field, where soil strength really matters. Field CBR Test Sets contain everything you need to perform those tests. You get quick relative strength determinations without relying on tests. Two models are available, each with a loading jack and manual crank. Field tests involve forcing a piston into the soil to see just how strong it is.

Our CBR Field Test Set has a two-speed jack with 10,000lbf (44.5kN) capacity and 3.5in (89mm) total travel. That flexibility will meet almost any height requirement you throw at it. The load frame specs include a gear box and lift capacity—equipment you'd typically use for the load. The relation between the depth of penetration and the applied load is what makes CBR determinations possible. Comparing those field testing results to ASTM recommendations is a big part of what you'll be doing.

The test set includes 2,000lbf and 5,000lbf Load Rings with dial gauges, a Swivel Base for the Jack, Penetration Piston with Connector and Extension Sets, two 10lb and two 20lb surcharge masses, a 10lb/10in diameter Surcharge Plate, Support Bridge, long dial support bridge and Dial Indicator with magnetic holder. That penetration dial gauge, included with a holder, gives you precise readings. Each item is included with the test set—and available separately as replacement or extra. You'll also get slotted surcharge weights, piston extension, mechanical jack, connector set, accessories, steel bridge support, magnetic indicator, extension and connector set, swivel head, proving ring and three surcharge masses. Additionally, consider exploring the J-Ring Test Set for Self-Consolidating Concrete Mixtures for evaluating SCC mixtures.

What you can do with the CBR Test Set

It's portable and easy to use. On-site testing is a breeze. You get a complete kit with all the components you need for field CBR testing. The two-speed jack has a 10,000lbf (44.5kN) capacity and 3.5in (89mm) total travel. Load rings with dial gauges give you measuring accuracy. The penetration piston is flexible—and so is the support bridge and dial indicator with magnetic holder.

You can simulate heavy loads with the surcharge weights and plate. The CBR Test Set is designed for field testing, allowing you to quickly determine the relative strength of soil without relying on lab tests. That involves comparing the depth of soil penetration against the applied load on the piston.

Applications and testing

The CBR Test Set is for geotechnical testing—soil strength testing. It's used for field CBR testing, on-site bearing capacity testing. That involves forcing a piston into the soil to assess its strength. You can also use it to simulate laboratory CBR tests.

Construction and mining—where geotechnical engineering meets the demands of the field. That's where our equipment excels. We offer portable, easy-to-use solutions for on-site testing. That means you can get the data you need where you need it: in the field.

One of the key features of our equipment is its ability to simulate a loaded dump truck as a reaction load. That gives you realistic testing conditions. And that's exactly what you need to determine the CBR value of soil. By making those determinations through field tests, you get a practical alternative to laboratory tests.

Our equipment is designed to be easy to operate. That includes a two-speed jack and manual crank. That means you can get started quickly and easily.

Our CBR Test Set is used in a variety of engineering applications. Road construction and foundation design are just two examples. It also helps you determine soil suitability for construction projects.
