MISW investigations are used in
QA or forensic investigation of subgrade, base & top asphalt/concrete
pavement layers as well as for structures & tunnels.
The Multiple Impact Surface Waves (MISW) systems are
designed to measure asphalt and concrete pavement surface layer (Single
Layer software) thicknesses to within ~0.2 to 0.4 inches (~5 to 10
mm) when calibrated with limited cores. In addition, the MISW system
can be used to measure surface wave velocity profiles vs. depth from
which Young’s (elastic) moduli and layer thicknesses are determined
(Single Layer and Multiple Layer software options) the pavement layer
thickness/moduli profile is used for mechanistic-empirical pavement
design and rehabilitation studies. The MISW system can be used for
Quality Assurance/Quality Control (QA/QC) purposes for each layer of
a pavement system during construction to provide pavement system layer
thickness (typically surface pavement layer) and moduli data (for pavement,
base, and subgrade layers). In pavement rehabilitation projects, MISW
can be used to measure asphalt/concrete thickness/moduli as well as
the thickness/moduli of the underlying base, and subgrade layers of
pavement systems.
The MISW test method utilizes many of the same principles, equations,
and data collection procedures as the SASW method. The differences
between the two methods are predominantly in the data collection and
processing where, the MISW method is based on multichannel data processing
techniques, developed for the Multichannel Analysis of Surface Waves
(MASW) method. All of the data taken during MISW testing is analyzed
together to create a dispersion image or phase velocity spectrum.
Training
Hands-on training is available for the Multiple Impact Surface Waves Nondestructive
Testing Method at our Wheat Ridge, Colorado (USA) location, which is a
suburb located appromately 15 minutes northwest of downtown Denver. Training
may be available at your location by one of our agents upon special arrangement.
