Thought...
300.5
6" , min. In trench below 2-in thick concrete or (((equivalent))).
Point is.
Pavement is not (((equivalent)) to concrete.
CONCRETE:A hard, strong construction material consisting of sand, conglomerate gravel, pebbles, broken stone, or slag in a mortar or cement matrix.
ASPHALT: 1. A brownish-black solid or semisolid mixture of bitumens obtained from native deposits or as a petroleum byproduct, used in paving, roofing, and waterproofing. 2. Mixed asphalt and crushed stone gravel or sand, used for paving or roofing.

Anything that would withstand the same force of pressure per foot. Asphalt can not do this. Have you seen a large truck drive over asphalt and make a indention into the asphalt, If it was concrete the large truck would not have the same effect.
