The Benkelman Beam (Figure 2), developed at the Western Association of State Highway Organizations (WASHO) Road Test in 1952, is a simple device that operates on the lever arm principle. Darter et al. This test has been carried out on top surface of existing conventional whitetopping to obtain the deflection measurements at edge and corner of each slab as shown in Figures 1 and 2. Resources Back to Resources. The specimens have to be temperature conditioned with a suitable climatic chamber (see \#climatic-chambers\#, model 10-D1429/A)and the compression test has to be performed with a testing compression machine of minimum 180 kN capacity for compaction and compression, as, for example the \#electromechanical-universal-tester_\#, model 70-S17C2.

: 5 kg H-3221HA Digital Indicator, Horizontal. BENKELMAN BEAM METHOD A. C. Benkelman devised the simple deflection beam in 1953 for measurement of pavement surface deflection. Benkelman Beam. Benkelman Beam Test OBJECTIVE: To determine the rebound deflection of a pavement under a standard wheel load and tyre pressure with or without temperature measurement by Benkelman Beam test.


[1991 [4]] recommends that the deflection used for subgrade modulus determination should be taken at a distance at least 0.7 times r/a e where r is the radial distance to the deflection sensor and a e is the radial dimension of the applied stress bulb at the subgrade “surface.” The a e dimension can be determined from the following:. The deformation or elastic deflection of pavement under a given load depends upon sub grade soil type, its moisture content and compaction, the thickness and quality of the pavement course, drainage conditions pavement surface temperature etc. TNZ T/1 June 1977 SP/ST1:77XXXX STANDARD TEST PROCEDURE FOR BENKELMAN BEAM DEFLECTION MEASUREMENTS Page 4 of 5 Pages (S - I) and (S - F) XT = 2(S - F) X(T) = 2(S - F) + 5.82 (I - F) 110 20 - t X20 = XT + 4. the use of the benkelman beam deflection test in control of construction and work, with discussions and closure. Adjustable feet for Benkelman beam, complete with two spirit level Calibration device 80-B0180/3 Calibration device for 35-T1100/BF Benkelman beam apparatus. The Benkelman Beam is used with a loaded truck – typically 80 kN (18,000 lb) on a single axle with dual tires inflated to 480 to 550 kPa (70 to 80 psi ).

Adjustable feet for Benkelman beam, complete with two spirit level Calibration device 80-B0180/3 Calibration device for 35-T1100/BF Benkelman beam apparatus. It is widely used all over the world evaluation of the requirements of strengthening of flexible pavements. Measures the deflection of a flexible pavement under moving wheel loads. Benkelman beam deflection measurements Published: June 1977 | Category: ... Road traffic engineers & consultants, Roading contractors.

The beam test shall be as per NZTA Specification T/1 except that the recordings for bowl deflection shall not be recorded or used in the deflection calculation.
To verify the correct performance of the apparatus. This instrument is available M.E.R.I. benkleman beam, road deflection measurement, uses. We also offer survey services include BBD (Benkelman beam deflection studies) along with the estimation of characteristic deflection calculations based on IRC-81, 1997. deflection tests have been utilized for a number of years by road authorities as a guide in assessing the structural adequacy of existing pavements.

Vertical dial indicator for the Benkelman Beam. the The vehicle used to carry out BBD test was having 81.70kN rear axle weight as per guidelines given in IRC: 81-1997. 1.INTRODUCTION The Benkelman beam instrument is used to measure the deflection of the road.
