1.1 This test method covers the measurement of deflections of paved and unpaved surfaces with a falling-weight-type impulse load device. These devices are commonly referred to as falling-weight deflectometers.

1.2 This test method describes the measurement of vertical deflection response ...

1.1 The flatjack test measures stress at a rock surface. The modulus of deformation and the long-term deformational properties (creep) may also be evaluated.

1.2 Limitation -The flatjack test measures stresses only at the surface of the test chamber. Undisturbed stress levels must be de...

1.1 This test method covers the nondestructive determination of the thickness of bound pavement layers using Ground Penetrating Radar (GPR).

1.2 This test method may not be suitable for application to pavements which exhibit increased conductivity due to the increas...

This guide is intended to provide standardized procedures for evaluating ultrasonic search units. It is not intended to define performance and acceptance criteria, but rather to provide data from which such criteria may be established.

These procedures are intended to evaluate the charac...

1.1 This guide describes measurement procedures for evaluating certain characteristics of ultrasonic search units (also known as "transducers") that are used with ultrasonic examination instrumentation. This guide describes means for obtaining performance data that may be used to define the acous...
