Benkelman Beam Deflection studies are one of the non-destructive techniques for the structural evaluation of flexible pavements. A well-compacted pavement section or one which has been well-conditioned by traffic deforms elastically under each wheel load application such that when the load moves away, there is an elastic recovery or rebound deflection of the deformed pavement surface. This is the basic…
Load testing is mainly used for assessing the flexural capacity of bridge. It is used to assess the condition and safety of bridge. The situations in which the testing is carried out if there is excessive creep deflection, materials defect, structural deterioration, uncertainties in current built in conditions , bomb or fire damage, or structural strength unknown. The load testing…
A?geological survey?is the systematic investigation of the?geology?beneath a given piece of ground for the purpose of creating a?geological map?or?model. Geological surveying employs techniques from the traditional walk-over survey, studying?outcrops?and?landforms, to intrusive methods, such as hand augering and machine-driven?boreholes, to the use of?geophysical?techniques and?remote sensing?methods, such as?aerial photography?and?satellite imagery. Such surveys may be undertaken by state, province, or national geological survey…
Ev2 Plate Bearing Test Set Static Deformation Testing Machine USAGE OVERVIEW: Ev2 Plate bearing test set is used to measure the settlement value of subgrade under static load, so as to evaluate the bearing capacity and deformation of subgrade.
The modulus of subgrade reaction (k) is used as a primary input for?rigid pavement?design.? It estimates the support of the layers below a rigid pavement?surface course?(the?PCC?slab).? The k-value can be determined by field tests or by correlation with other tests. There is no direct laboratory procedure for determining k-value. The value of k is in terms of MPa/m (pounds per…
Dynamic load test on piles is a method that can be used to evaluate pile load-carrying capacity by applying a dynamic load. The method is valid, reliable, and helps evaluate pile capacity quickly compared to static load tests, and one or more piles can be tested per day as per the requirement of the project. Dynamic load test for piles…
The?Pile Load Test?is the most reliable method of determining the load carrying of a pile. This test can be performed either on a working pile that forms the foundation of the structure or on a test pile. Pile loading test?is one of the most common methods for testing the actual in-situ load capacity of any pile. The test method involves…
Most of the time, we dont often pay attention to the piles after it is being cast. But, just like any other structural members, they are also prone to structural failures and sometimes noticing these damages is already too late when the settlement occurs. This failures and damages can be associated with the pile design or pile construction and workmanship.…
The Pile Integrity Tester (PIT) gives peace of mind that a pile or shaft is free of major cracks and voids, prior to construction of the superstructure. It may be used on most concrete or wood foundations. The PIT may also be used to test piles integral in the structure, such as those supporting existing bridges or towers, and may…
The plate load test?is a field test, which is performed to determine the ultimate bearing capacity of the soil and the probable settlement under a given load. This test is very popular for the selection and design of the shallow foundation. For performing this test, the plate is placed at the desired depth, then the load is applied gradually and…
