It is used in large road construction projects has increased considerably in recent years. This apparatus, mounted on a rolled steel joint cantilevered from the back of the truck or fitted

to the underside of a mobile frame, can be used to determine the bearing capacity of soils quickly and efficiency. This method of testing in-situ, using piston penetration, is useful for

determining the load carrying capacity in the field, when the in -place density and water contents are such that the degree of saturation is 80% or greater. When the material is coarse grained and cohesionless so that it is not affected b changes in the water content and when

the material has been in- place. Similar to above but supplied with bench mounting type

5000kgf. Capacity load frame motorized, in place of load frame hand operated. The lead screw of the load frame has a single constant rate of travel of 1.25mm/minute. Dial Gauge
