E2835-11 1 2 3 4 5 page sstarting from page current page. The identification was carried out on the basis of displacements recorded during impact test. Posted by Frank Georg Schulz at 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.

For gravel surfaces it is recommended that a thin layer of fine sand be placed over the test point. Download full text in PDF Download.

International standard ASTM E2835-11 for Light Weight Deflectometer HMP LFG

The electronic file may not be reproduced in any way. 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. This completely uniform contact can depict the load plate deflection that is like the deflection of the unbound material’s surface.

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 sensitivity of the dynamic stiffness modulus of the ground in the process of loading and unloading was confirmed.

This way, you can be sure that you are using a device that can withstand extreme temperatures, dust, vibrations, and rain.

ASTM grants you a license as follows: 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. 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.

Satm was assumed that nonlinearity of the ground was described by changing in time values of the dynamic stiffness modulus. Historical Version s – view previous versions of standard. 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.

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.

All xstm must go through testing and pass internationally acceptable calibration standards before being made available. Some manufacturers provide a one-year warranty for their LWDs, so they can perform the necessary repairs or recalibration as required.

Deflection can be measured above the center of the load plate, which in turn must be in contact with the unbound material under the plate. 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. Author links open overlay panel Wojciech Gosk.

All light weight deflectometers must be ASTM E certified and must come with a certificate to prove it.

Accordingly, the test surface shall be as clean and smooth as possible with loose granules and protruding material removed. Under a Creative Commons license. Register for a trial account. The deflection is measured at the center of the top of the load plate see Note 1.

For fine-grained materials, this will help in obtaining a reasonably uniform contact between the load plate and the surface. By continuing you agree to the use of cookies.
