Measurements of the Stiffness and Thickness of the Pavement ...
Enhanced resonance search (ERS) is a nondestructive testing method that has been created to evaluate the quality of a pavement by means of a special instrument called the pavement integrity scanner (PiScanner). This technique can be used to assess the thickness of the road pavement structure and the profile of shear wave velocity by using the principle of surface .

Influence of asphalt pavement on damping ratio and resonance ...
· Table 3 summarizes the resonance frequencies and damping ratios of the two bridge configurations without and with asphalt pavement. The effect of the asphalt pavement on the resonance frequency is a decrease of the first resonance frequency from – Hz for the CLT bridge and from – Hz for the SLP bridge. This result suggests that ...

Existing Surface Preparation for Overlays – Pavement Interactive
This equipment strikes the rigid pavement at low amplitude with a small plate at the resonant frequency of the slab (usually about 44 Hz) causing the slab to break apart (Figure 16) (Roberts et al., 1996 [2]). Usually it takes about 14 to 18 passes for a resonant pavement breaker to rubblize an entire m (12 ft.) lane (NCAT, 2001 [4]). Multi ...

Different from traditional footbridges in which resonant responses up to 5 Hz are considered for the vibration serviceability analysis, very lightweight structures may show nonnegligible nonresonant responses up to even 10 Hz (Russell et al., 2019). Additionally, the mass of the occupants may not be negligible as compared to the structural modal mass and, consequently, .
