Frozen soil ball probe test set


Ball test 


   Frozen soil ball probe test is conducted to measure the limit long-term value of equivalent soil cohesion for fine-grain and silty sands, clays with organic matter content up to 10 %. 
  The equivalent cohesion limit value is determined by the depth of a ball probe penetration into a soil sample under a constant load at an assigned test temperature.  
 The probe set includes a loading system and a chamber with a ball probe. 
 The set is equipped with an automatic control confined cycle loading and data acquisition from load and displacement sensors, with exception of manually controlled loading.   Application of stepped-operation motor for applying vertical load enables tests with variable deformation rate, excluding the one with the manual deformation control. Application of a ball-type motor for applying a vertical load enables tests with different deformation rates, including the one with constant deformation rate.
