Which description best matches field or laboratory testing of bridge component materials and/or members?

Explanation:
Physical testing refers to actually measuring how bridge materials and components behave in either the field or the lab. It involves applying controlled conditions or loads to specimens or to field components to determine properties like strength, stiffness, durability, and performance. This can include destructive tests (for example, crushing concrete, bending steel) as well as nondestructive tests (like ultrasound or surface hardness tests). The other terms are specific items or phenomena rather than the testing process: raveling is asphalt surface deterioration, rebar is reinforcement steel, and a pier is a bridge support.
