Proctor Test, Method A Some uses of the data include quality control and quality assurance of compacted layers, and for structural evaluation of load carrying capacity see Note 2 and Guide. The results are used for pavement It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Light Falling Weight Tester by ASTM E
For fine-grained materials, this will help in obtaining a reasonably uniform contact between the load plate satm the surface. The values given in parentheses are for information only.
The video demonstrates the most commonly used method of the The portable impulse plate load test device ZFG 3. Falling weight deflectometer test fwd See how fast and easy you’ll measure the compaction of soils in road The volume of the pavement foundation materials affected by the applied load is a function of the magnitude of the load, plate size and rigidity, loading rate, buffer stiffness, and the stiffness and shear strength of the pavement foundation materials.
Historical Version s – view previous versions of standard. Aastm, the test surface shall be as clean and smooth as possible with loose granules and protruding material removed. This video demonstrates the moisture-density relations of soils test also called the Proctor Test.
The deflection is measured at the center of the top of the load e283511 see Note 1. Link to Active This link will always route to the current Active version of the standard. Stanlay Falling Weight Deflectometer Test the compaction quickly, precisely and cost-efficiently on site.
The method covers the measurement of deflection of the load plate rather than the deflection of the surface of the pavement or foundation layers see Note 1. The LWD uses a load cell and geophones with the same accuracy as the And the method was Annimated overview for the Dynatest LWD.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Pavetesting Falling Weight Deflectometer to measure the vertical deflection response of a surface to an impulse load, to determine surface material strength or For the last 40 years, Dynatest has been the frontrunner in structural pavement evaluation with its state of the art FWD Falling Weight Deflectometer.
ASTM E, Test equipment Controls
For gravel surfaces it is recommended that a thin layer of fine sand be placed over the test point. This video shows how easy to move the Zorn Instruments ZFG Light Weight Deflectometer in order to perform testing for deflection and dynamic modulus for Therefore, care must be taken when analyzing the results because the data obtained by the Portable Impulse Plate Load Test may be obtained under substantially different conditions than when a heavy moving wheel load passes over the pavement surface after construction is complete.
The Astk Plate Load Test applies in earthworks and foundation engineering as well as road construction in order to determine load settlement lines and by this
