Plate load test (ASTM D1194) | Limitations and Advantages

• Plate load test  (ASTM D1194):

Plate load test is a type of test which is performed on a model foundation. This test is just restricted to less deep or shallow depths; this test is usually in general performed in open excavation. But in Europe an alternative method is used instead of it, the method of screw plates test which was developed in Europe and is now implemented there. The advantage of this test is that it is useful at any depth in the bore holes. This test can be used in the design of pavements and in the settlement analysis of the foundations, as it provides the modules for the sub grade reactions.

Limitations And Advantages:

• Plate load test s a expensive way of testing therefore is seldom used when there is no other way of testing a sample.
• As it is a short duration test therefore the results in case of clays are usually unsatisfactory.
• In case of layered strata, the data obtained from small sized plates is mostly misguiding when we are dealing with large foundations.
