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 Some manufacturers provide a one-year warranty for their LWDs, so they can perform the necessary repairs or recalibration as required. The standard is internationally recognized for measuring deflections using a portable impulse plate load apparatus.

Ast, sign into an account with a subscription to this content, or email for help at support madcad. But before you can use an LWD, you need 2e835-11 make sure that it is calibrated to ASTM E, an international standard for calibrating this type of device. 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.
LWDs are lightweight and portable devices that can provide a more accurate data on the rigidity of unbound materials before, during, or after construction. Remember me for one month.
ASTM E2835 – 11(2015)
Historical Version s e2853-11 view previous versions of standard. The volume of the pavement foundation materials affected by the applied load is a function of the magnitude of the load, plate size e28835-11 rigidity, e28351-1 rate, buffer stiffness, and the stiffness and shear strength of the pavement foundation materials.
ASTM E testing methods can determine the aastm deflection, which results from the application of impulse load. Author links open overlay panel Wojciech Gosk. Are you sure you want to empty the cart?

The sensitivity of the dynamic stiffness modulus of the ground in the process of loading and unloading was confirmed. Procedia Engineering Volume, Pages Link to Active This link will always route to the current Active version of the standard. The identification was carried out on the basis of displacements recorded during impact test. Keywords stiffness modulus of the ground.

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. Recommended articles Citing articles 0.

TERRATEST GmbH: What Is ASTM E Standard For LWD Testing
Accordingly, the test surface shall be as clean and smooth as possible with loose granules and protruding material removed. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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.
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.
Published by Elsevier Ltd. This way, you can be sure that you are using a device that can withstand extreme temperatures, dust, vibrations, and rain. There were no books found for the applied search filters.
The deflection is measured at the center of the top of the load plate see Note 1. Under a Creative Commons license.
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.

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 original calculation program, based on finite difference method which enables the description of wave propagation in cylindrical soil solid under impact load, was used.
