The liquid limit set performs Atterberg or liquid limit tests in accordance with ASTM specifications. It determines the water content at which soil changes from a liquid to a plastic state. A soil sample placed into a cup in the machine separates into two halves using a grooving tool. The crank on the machine rotates so that the cup holding the sample strikes the base of the test machines. Machines are available with counters and motors if preferred. The soil grinder quickly prepares dry soils samples for limit tests, particle size analysis and other standard lab tests. It preserves true grain size for accurate and repeatable test results. The resiliency tester measures resiliency of the hard rubber base of the liquid limit machines. Complete tests within a 90 day interval to ensure the base meets ASTM D4318 standards.
