Standard Penetration test (SPT) was performed during the execution of a survey, within the N mismo.Permite calculate the value of resistance to penetration. Can be correlated with density, angle of friction, and seats. It also allows for altered sample to test blind Puntazo laborat.La used in grounds with bowling, the other in other granular soils. It has to choose the adecuada.La penetration may be altered by several factors: depth of the test, stability of the survey, etc.

Dynamic penetration tests (DPSH or delete) the principle is the same as the spt, except that here the penetrometer will be rejected or down to achieve the desired depth in sink varillaje.Consiste adding a desechableunida Puntazo a linkage, and measured 20 cm bajada.Vane Test or windlass. It is a trial to determine the shear strength of soft cohesive soil. It is a device consisting of a central rod and four blades that spin, measuring the resistance taking into account certain factors.

Sclerometer or Hammer Smith considers the approximate compressive strength by a correlation with tables. It is based on a hit with rebounds, and has much chance of testing. Point load test PLT (Point load test. Calculate the compressive strength in irregular fragments or appropriate probe witnesses. It gives consistent and slate rocks or anisotropic. The formula is simple, we calculate the index I = P/D2 For values of different diameters of 50 mm, should be corrected. Load plate test. It can be done in trenches, soil and asphalt. It consists of making a vertical load in stages.

We need a truck that makes the response to the effort of the plate. The most commonly used plate is a disc of 30 cm in diameter, with a hydraulic jack, to get the ground breaking. There are a wider variety of tests, but the most used are those stated in this template. So are those included in the review. In the book available for the future, all information, charts, and advice to support them or understand them.
