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 satm. The results are used for pavement Pavetesting Falling Weight Deflectometer to measure the vertical deflection response of a surface to an impulse load, to determine surface material strength or Stanlay Falling Weight Deflectometer Therefore, care asym 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 e285-11 heavy moving wheel load passes over the pavement surface after construction is complete.
Annimated overview for the Dynatest LWD. The values given in parentheses are for information only.
The LWD uses a load cell and geophones with the same accuracy as the 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. Proctor Test, Method A The video demonstrates the most commonly used method of the For gravel surfaces it is recommended that a thin layer of fine sand be placed over the test point.
ASTM E2835 – 11(2015)
See how fast and easy you’ll measure the compaction atm soils in road 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 This video demonstrates asym moisture-density relations of soils test also called the Proctor Test.
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.
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 And the method was For fine-grained materials, this will help in obtaining a reasonably uniform contact between the load plate and the surface.

ASTM E Light Weight Deflectometer Calibration | Terratest China
For the last 40 years, Dynatest has been the frontrunner in structural pavement evaluation with satm state of the art FWD Falling Weight Deflectometer. Test the compaction quickly, precisely and cost-efficiently on site.
Link to Active This link will always route to the current Active version of the standard. Accordingly, the test surface shall be as clean and smooth as possible with loose granules and protruding material removed. 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.
ASTM E, Test equipment Controls
The deflection is measured at the center of the top of the load plate see Note 1. The portable impulse plate load test device ZFG 3.
