Standard Test Method for Deflections with a Falling-Weight-Type Impulse Load Device

Importancia y uso:

4.1 This test method covers the determination of pavement surface deflections as a result of the application of an impulse load to the pavement surface. The resulting deflections are measured at the center of the applied load and at various distances away from the load. Deflections may be either correlated directly to pavement performance or used to determine the in situ material characteristics of the pavement layers. Some uses of data include structural evaluation of load carrying capacity and determination of overlay thickness requirements for highway and airfield pavements.
