Statistical approach for layer moduli determination 16 FWD Deflection Plot MODULUS 6.0 (Cont.) 17 Layer Moduli Plot MODULUS 6.0 (Cont.) 18. To convert (ksi) to (MPa), multiply by 6.89ĭata from ASM Engineering Materials Reference Book, Second Edition, Michael Bauccio, Ed., ASM International, Materials Park, OH, p106, (1994). MODULUS 6.0 FWD from ITD Backcalculation method. RUPTURE STRENGTH OF REFRACTORY METAL ALLOYS Find a library where document is available.Table 245.Furthermore, the results showed that the M sub r prediction was significantly enhanced when soil properties were included as variables within the regression model. The results of the regression analysis showed that among all backcalculated FWD moduli, those backcalculated using ELMOD 5.1.69 software had the best correlation with M sub r. The E sub FWD/M sub r ratio was also found to be significantly affected by the backcalculation method. The FWD data gathered from different test sites, including the Zanjan-Tabriz, Eivanekey-Garmsar and Garmsar-Semnan freeways and also Rafsanjan. Furthermore, this ratio was higher at lower M sub r values and hence weaker subgrade soils. In this research, three software programs, MODULUS 6.0, ELMOD 5.0 and EVERCALC 5.0, were used to do the elasto-static back-analysis and the DBSID program was employed for the dynamic backcalculation.

The results of this study showed that the E sub FWD/M sub r ratio ranged from 0.51 to 8.1 for the tested subgrade soils.

Statistical models were developed that can relate the laboratory measured M sub r to FWD moduli backcalculated (E sub FWD) using each of the methods considered. S (B(D3)-b(d3))/(6D -> (0.1(0.13)-0.01(0.013))/(60.1). The laboratory testing program consisted of conducting repeated load triaxial M sub r tests, physical properties, and compaction tests on soil samples obtained from tested sections.

In addition, the AASHTO and Florida backcalculation equations were used for comparison. Three backcalculation software packages were used to interpret the FWD data: ELMOD 5.1.69, MODULUS 6.0, and EVERCALC 5.0. The tested sections covered the common subgrade soil types found in Louisiana. In Project 0-4495 an integrated software package called PAVECHECK was developed to merge the FWD and GPR data together with digital video images of. There is substantial synergy in combining the analysis capabilities of both systems. The field testing program included testing various sections in 10 pavement projects within Louisiana. Application of Constrained Extended Kalman Filter in Layer Moduli Backcalculation Jae-Woong Choi, Rongzong Wu, and Juan M. The GPR data are processed with the COLORMAP analysis system, and the FWD data are processed with MODULUS 6.0.
#Backcalculation modulus 6.0 manual
This new Windows version has an automatic segmentation algorithm and a new manual segmentation routine. Using Modulus 6.0, transportation engineers can perform structural evaluations of pavements and identify moduli values for design in the familiar Windows environment.
#Backcalculation modulus 6.0 upgrade
M sub r is used in the design and evaluation of pavement structures. Modulus 6.0 is the Windows upgrade of Modulus 5.1. Estimation of Resilient Modulus of Subgrade Soils Using Falling Weight Deflectometerįield and laboratory testing programs were conducted to develop models that predict the resilient modulus (M sub r) of subgrade soils from the falling weight deflectometer (FWD) test results.
