چکیده
|
A series of surface wave tests,namely the spectral analysis of surface wave (sasw) test,was done on asphalt pavement to study the effect of receiver distance,s; the height of dropping steel balls,h; and the mass of the source,m on the results of sasw evaluation. for each test,four steel balls with different masses,namely0.067kg,0.228kg,0.537kg,and 1.805kg,were used as sources,and the balls were dropped from varying heights,0.25m and 0.50m. this test was conducted with two different configurations,in which the receivers were located 0.15m and 0.30m apart. this paper presents the results of the test in terms of maximum and minimum wavelength. the results proved that larger receiver distance yields large wavelength,and vice versa. the similar trend is observed when the mass of the dropping ball is increased. the height of the falling steel ball,however,did not have significant impact on the results of the sasw evaluation. © 2016 penerbit utm press. all rights reserved.
