Describe the methods used to determine static and dynamic deflection of pavements. To what extent are these tests used in pavement rehabilitation management?
What will be an ideal response?
The methods used to determine the static and dynamic deflection of
pavements are measurement of static deflections (Benkelman Beam), and
measurement of dynamic or repeated loads (Dynaflect). These methods are rarely
used to evaluate pavement condition, but deflection data are used for design
purposes and to develop strategies.
