Applicable On:

Asphalt and Concrete Pavements, Slabs, Tunnel Liners, Structural Concrete

Test for:

Determination of stiffness profiles, i.e., velocity and thicknesses of thin layered systems (typically not exceeding 3 m) without coring and with only 1-sided access conditions. This method is also used to measure the depth of surface-opening cracks. The SASW method is a powerful tool for identifying material condition properties at various depths through the determination of the variation of material stiffness vs. depth in layered systems.

  • Identify fire, frost and cracking damage and depth of damage in concrete
  • Estimate strength of concrete, masonry and rock with destructive correlations
  • Measure depth of vertical (surface-opening) cracks
  • Determine asphalt moduli/thickness and pavement layers
  • Look through tunnel linings to check concrete, shotcrete, rock depth and competency

Models Available:

  • SASW-S: 2 accelerometers and SASW bar (shown at far right of system image) with spacings from 2.4" to 32" (6 -80cm)
  • SASW-S + G: Call for details regarding this combination with a geophysical SASW system
  • * Combine with IE-1 and SIR-1 systems for a complete pavement nondestructive evaluation system!
