This is for estimating the bearing capacity of shallow foundations in situ and for the design of flexible pavement. In the test procedure a steel plate is subjected to gradually increasing load and settlements of the plates recorded. Maximum bearing capacity is noted as that load at which the plate starts sinking rapidly.

 

Specifications:

Note:

 

1) When plates of size more than 30cm.sq are used in order to prevent deflections of the edge, a series of smaller plates are advised to be placed concentrically on the bottom plate.

2) Flexible rubber pipe 1mtr. Length can be supplied for the hydraulic jack in place of metal pipe at extra cost. For site testing load trusses to meet the reaction of loading are avaiLable in different capacities as under.
