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. No further reproductions authorized. The paper presents a method of the stiffness modulus identification of the soil built-in embankment, tested by the Light Falling E283-511 Deflectometer ZFG Therefore, care must be taken when analyzing the results because the data obtained by the Portable Impulse Plate Load Test may be ashm under substantially different conditions than when a asfm moving wheel load passes over the pavement surface after construction is complete.

If you like to setup a quick demo, let us know at support madcad. It was assumed that nonlinearity of the ground was described by changing in time values of the dynamic stiffness modulus. All devices must go through testing and pass internationally acceptable calibration standards before being made available. There were no books found for the applied search filters.

The identification was carried out on the basis of displacements recorded during impact test. Remember me for one month.

Enter your personal account email address to request a password reset: Abstract The paper presents a method of e8235-11 stiffness modulus identification of the soil built-in embankment, tested by the Light Falling Weight Deflectometer ZFG 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 e283511 Guide.

This completely uniform contact can depict the load plate deflection that is like the deflection of the unbound material’s surface. ASTM E testing methods can determine the plate deflection, which results from the application of impulse load. The values given in parentheses are for information only. Accordingly, the test surface shall be as clean and smooth as possible with loose granules and protruding material removed. Author links open overlay panel Wojciech Gosk.

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.

Adtm sensitivity of the dynamic ee2835-11 modulus of the ground in zstm process of loading and unloading was confirmed.

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. Some manufacturers provide a one-year warranty for their LWDs, so they can perform the necessary repairs or recalibration as required.

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. LWDs are lightweight and portable devices that can provide a more accurate data on the rigidity of unbound materials before, during, or after construction.

Content only available by subscription. The deflection is measured at the center of the top of the load plate see Note 1. For gravel surfaces it is recommended that a thin layer of fine sand be placed over the test point.

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

The volume of the pavement e8235-11 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.
