  2. Pallesthesia - Wikipedia

    en.wikipedia.org/wiki/Pallesthesia

    Pallesthesia (\ˌpal-es-ˈthē-zh(ē-)ə\), or vibratory sensation, is the ability to perceive vibration. [ 1 ] [ 2 ] This sensation, often conducted through skin and bone, is usually generated by mechanoreceptors such as Pacinian corpuscles , Merkel disk receptors, and tactile corpuscles . [ 1 ]

  3. Crosshole sonic logging - Wikipedia

    en.wikipedia.org/wiki/Crosshole_sonic_logging

    Crosshole sonic logging (CSL) is a method to determine the structural integrity of drilled shafts and other concrete piles. The CSL method is considered to be more accurate than sonic echo testing in the determination of structural soundness of concrete within the drilled shaft inside of the rebar cage. This method provides little indication of ...

  4. Ultrasonic pulse velocity test - Wikipedia

    en.wikipedia.org/wiki/Ultrasonic_pulse_velocity_test

    An ultrasonic pulse velocity test is an in-situ, nondestructive test to check the quality of concrete and natural rocks. In this test, the strength and quality of concrete or rock is assessed by measuring the velocity of an ultrasonic pulse passing through a concrete structure or natural rock formation. This test is conducted by passing a pulse ...

    en.wikipedia.org/wiki/Falling_weight_deflectometer

    A falling weight deflectometer (FWD) is a testing device used by civil engineers to evaluate the physical properties of pavement in highways, local roads, airport pavements, harbor areas, railway tracks and elsewhere. The data acquired from FWDs is primarily used to estimate pavement structural capacity, to facilitate overlay design or ...

    Layers in the construction of a mortarless pavement: A.) Subgrade B.) Subbase C.) Base course D.) Paver base E.) Pavers F.) Fine-grained sand. In highway engineering, subbase is the layer of aggregate material laid on the subgrade, on which the base course layer is located. It may be omitted when there will be only foot traffic on the pavement ...
