In each increment; the load stays static for 15 minutes according to ASTM D 94 specification. The results showed that the plate settlements of the soil under. ASTM: D AASHTO: T Apparatus. Loading platform of sufficient size and strength to supply the estimated load. Hydraulic or mechanical.

Your email address will not be published. The load transmission takes place via the application of a force by means of a hydraulic system of thrust, of a circular plate. xstm
The plate load test shall be carried out at locations as shown in the drawings or as directed by the Engineer using approved equipment. Submit sstm article or Ask any query.
Such footing must have a depth of not less than two thirds of their width. The details of equipment including the certificates of instrument and copies of calibration charts axtm approved agency and setup for conducting the plate load test shall be submitted for the approval by the Engineer before commencement of the test.

Most viewed Last 7 days Posts Weight of steel bars per meter — Weight of steel bars formula views Definition of Steady Flow and Unsteady Flow views Soil Sampling Disturbed and Undisturbed soil samples views Allowable bearing capacity Safe bearing capacity views Definition of Principal stresses Principal plane Principal Axis views. 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.
The applied load shall be measured using calibrated electronic load cell.
The subsidence induced by the ground plate are simultaneously detected by centesimal or digital data acquisition systems, integral with d194 frame of reference outside the area of influence of the applied load. This site uses Akismet to reduce spam. The load test consists in transmitting to the soil to be tested and the subsequent increasing load increments, detecting simultaneously the sagging and therefore allows to directly determine a form of deformation or compressibility of the soil.
Precise leveling optical survey to accuracy of 0. 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. Learn how your comment data is processed. Miscellaneous Apparatus required, including loading columns, steel shims, and other construction tools and equipment required for preparation xstm the test pits and loading apparatus.
Of fundamental importance, in any case, is the use of the proper contrast medium whose mass is a function of the expected load. The Hydraulic or Mechanical Jack Assembly should have sufficient capacity to provide and maintain the maximum estimated load but not less than 50 tons in any case.
The Settlement-Recording Devices, such as dial gauges should be able to measure to an accuracy of at least 0. In rock, plates larger than mm diameter may d119 used, depending on the jointing frequency. Plate Load testing is usually used for the verification of the bearing capacity of the land of the substrate, of the foundation layer and the base layer astk the flooring, although it is not uncommon to astj use to investigate the bearing capacity of the soil surface or to the state compaction of granular zstm and road surfaces.
The plate bearing load test shall be discontinued if any of the following occurs: For bearing plates, three circular steel bearing plates, not less than 25mm in thickness and varying in diameter from mm to mm including the minimum and maximum diameter specified or square steel bearing plates of equivalent area.
The reference beam and measuring devices should be protected asym the direct rays of the sun and from wind by means of tarpaulins or other forms of shelter, to minimize errors of measurement which can easily arise from these causes.
Plate load test is a type of test which is performed on a model foundation.
