The deflection is measured at the center of the top of the load plate see Note 1.

In addition the electronic files may not be downloaded or distributed elsewhere over computer networks or otherwise. It is the d2835-11 of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
The original calculation program, based on finite difference method which enables the description of wave propagation in cylindrical soil solid under impact load, was used.

ASTM grants you a license as follows: It was assumed that nonlinearity of the ground was described by changing in time values of the dynamic stiffness modulus.
For fine-grained materials, this will help in obtaining a reasonably uniform contact between the load plate and the surface. You currently cannot view this content. For gravel surfaces it is recommended that a thin layer of fine sand be placed over the test point.

Abstract The paper presents a method of the stiffness modulus identification of the soil built-in embankment, tested by the Light Falling Weight Deflectometer ZFG Enter your personal account email address to request a password reset: Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Soil compaction quality can be determined by using a light weight deflectometer, a reliable and noninvasive testing device used in a wide range of applications like civil engineering, earthworks, construction, and landscaping.

The identification was carried out on the basis of displacements recorded during impact test. Some uses of the data include quality control and quality assurance of compacted layers, and for structural evaluation aztm load carrying capacity see Note 2 and Guide. But before you can use an LWD, you need to make sure that it is calibrated to ASTM E, an international standard for calibrating this type of device. The values given in parentheses are for information only.

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.

Posted by Frank Georg Schulz at All devices must go through testing and pass internationally acceptable calibration standards before being made available. 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 2e835-11 than when a heavy moving wheel load passes over the pavement surface after construction is complete.

Are you sure e28335-11 want to empty the cart? 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. Keywords stiffness modulus of the ground. No further reproductions authorized. All light weight deflectometers must be ASTM E certified and must come with a e2835-1 to prove it.
LWDs are lightweight and portable devices that can provide a more accurate data on the rigidity of unbound materials before, during, or after construction.
