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

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

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 e835-11.

It was assumed that nonlinearity of the ground was described by changing in time values of the dynamic stiffness modulus. Procedia Engineering Volume, Pages There were no books found for the applied search filters.

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. Author links open overlay panel Wojciech Gosk. The paper presents a method of the stiffness modulus identification of the soil built-in embankment, tested by the Light Falling Weight Deflectometer ZFG Under a Creative Commons license.

No items in cart. Accordingly, the test surface shall be as clean and smooth as possible with loose granules d2835-11 protruding material removed. 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.

All devices 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. Download full text in PDF Download. 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 identification was carried out on the basis of displacements recorded during impact test. Soil compaction quality can be determined by using a light weight deflectometer, a reliable and noninvasive testing device astj in a wide range of applications like civil engineering, earthworks, construction, and landscaping.

LWDs are lightweight and portable devices that can provide a more accurate data on the rigidity of unbound materials before, during, or after construction. Link to Active This link will always route to the current Active version of the standard. Newer Post Older Post Home.
