| Summary: | Pavement assessment is significant in the
maintenance and rehabilitation process. Spectral Analysis
of Surface Waves (SASW) is one of the seismic testing
where it is a non-destructive, inexpensive, convenient, and
quick method to assess soil and rock mass characteristics as
an alternative to the conventional method. Coring, which
requires the drilling of the pavement, is the most popular
practice. However, this method is not only disrupting the
pavement condition but also time-consuming, expensive,
and labor-intensive. Thus, this paper aims to use the
SASW method to classify the pavement layers by evalu�ating the shear wave velocity and pavement modulus of
rigid pavement of the taxiway at Kuala Lumpur International Airport (KLIA), Sepang. The measurement
was done using two accelerometers acting as receivers and
one impact hammer acting as a source on a taxiway site at
KLIA. Based on the principle of stress waves that propa�gate through elastic elements, Rayleigh wave movements
were monitored. The Rayleigh wave energy was generated
using a set of transient impact sources with a variety of
frequencies, and their potential to disperse across the sur�face layer of the pavement was explored which was applied
in the SASW method. For the processing of the data taken
at the field site, WinSASW software was used to mask the
unprocessed data to get the dispersion curve which then
obtained the shear wave velocity profile through the
inversion process. The shear wave velocity was then used
to determine the pavement modulus by using the equation
developed by Yoder and Witczak. As a result, the shear
wave velocity and modulus obtained for rigid taxiway in
this research were between 1300 and 3000 m/s and 10 9 109
–60 9 109 Pa for the top layer (asphalt concrete)
while 3000–3600 m/s and 60 9 109
–80 9 109 Pa for the
second layer (cement-treated base). The SASW method has
been proved to minimize labor, time, and expenses while
delivering a quick and reliable outcome for a rigid pave�ment assessment without disrupting the pavement
condition. |
