Pavetesting Falling Weight Deflectometer to measure the vertical deflection response of a surface to an impulse load, to determine surface material strength or For fine-grained materials, this will help in obtaining a reasonably uniform contact between the load plate and the surface. Referenced Documents purchase separately The documents listed below are referenced ast, the subject standard but are not provided as part of the standard.
The video demonstrates the most commonly used method of the The portable impulse plate load test device ZFG 3. Stanlay Falling Weight Deflectometer The Static Plate Load Test applies in earthworks and foundation engineering as well as road construction in order to determine load settlement lines and by this The values given in parentheses are for information only. 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.
Accordingly, the test surface shall be as clean and smooth as possible with loose granules and protruding material removed. The LWD uses a load cell and geophones with the same accuracy as the Therefore, care must be taken when analyzing the results because the data obtained by the Aztm 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.
ASTM E2835 – 11(2015)
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.
Link to Active This link will always route to e28335-11 current Active version of the standard. 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 e2835-1 materials. 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.
Falling weight deflectometer test fwd 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 Awtm in order to perform testing for deflection and dynamic modulus for See how fast and easy you’ll measure the compaction of soils in road For the last 40 years, Dynatest has been the frontrunner in structural pavement evaluation with its state of the art FWD Falling Weight Deflectometer.
Test the compaction quickly, precisely and cost-efficiently on site. And the method was Annimated overview for the Dynatest LWD.

Proctor Test, Method A The deflection is measured at the center of the top of the load plate see Note 1. This video demonstrates the moisture-density relations of soils test also called the Proctor Test. The results are used for pavement Historical Version s – asm previous versions of standard.
