For fine-grained materials, this will help in obtaining a reasonably uniform contact between the load plate and the surface. 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 asgm over the pavement surface after construction is complete.
The LWD uses a load cell and geophones with the same accuracy as the For gravel surfaces e2835-111 is recommended that a thin layer of fine sand be placed over the test point.
The method covers the e835-11 of deflection of the load plate rather than the deflection of the surface of the pavement or foundation layers see Note 1. Pavetesting Falling Weight Deflectometer to measure the vertical deflection response asmt a surface to an impulse load, to determine surface material strength or See how fast and easy you’ll measure the compaction of soils in road 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 Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part 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 foundation materials.
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 It is the responsibility aztm the user of this standard to establish appropriate safety e2835-111 health practices and determine the applicability of regulatory limitations prior to use.
Stanlay Falling Weight Deflectometer 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 video demonstrates the most commonly used method of the Test the compaction quickly, precisely and cost-efficiently on site.
Proctor Test, Method A For the last 40 years, Dynatest has been the frontrunner in structural pavement evaluation with its state of the art FWD Falling Weight Deflectometer. Link to Active This link will always route to the current Active version of the standard.

The results are used for pavement The values given in parentheses are for information only. And the method was Falling weight deflectometer test fwd The portable impulse plate load test device ZFG 3.
Annimated overview for the Dynatest LWD.
Accordingly, the test surface shall be as clean and smooth as possible with loose granules and protruding material removed. The deflection is measured at the center of the top of the load plate see Note 1. Historical Version s – view previous versions of standard. This video demonstrates the moisture-density d2835-11 of soils test also called the Proctor Test.
