Seismic Pavement Analyzer (discontinued)
Portable Seismic Property Analyzer
Free-Free Resonance Cylinder Analysis
Laboratory measurement of resonant vibration
frequencies and modulus estimates on concrete,
asphalt, base, and soil cylinders.
Lab and field measurement of ultrasonic and
sonic surface wave velocity, with modulus
estimates on concrete, asphalt, base and soils.
Field measurement of surface waves, compressional
waves, impact echo, and impulse response with
three-layer modulus estimates.
