Nonlinear Effects in Falling Weight Deflectometer Tests

Nonlinear Effects in Falling Weight Deflectometer Tests Stokoe II, Kenneth H. Primary Author mixed material bibliography TRB 1992 en English p1-7 Trr No. 1355 Pavement Design, Management, And Performance Trr No. 1355 Pavement Design, Management, And Performance, pp. 1-7 The results of this studv indicate that material nonlinearities are localized and are important for FWD tests oil flexible pavements where the subgrade is relatively soft or the pavement is thin. In these cases. nonlinear effects increase peak displacements by at least 50%percent under a 20.000-Ib load but are negligible for receivers at 3 ft or more from the source. In general, a FWD test with a load of 2000 Ib or less would not result in any apparent nonlinear effects at anv pavement site. For FWD or rigid pavements or flexible pavcmcnts with a relatively stiff subgrade, nonlinearitics are also less pronounced FALLING WEIGHT DEFLECTOMETER 625.7(047.31) Perpustakaan Direktorat Bina Teknik Jalan dan Jembatan Direktorat Jenderal Bina Marga - Kementerian Pekerjaan Umum (NPP: 3273244A00000001) 0000004442 My Library 4216 machine generated
