(1) Note. Included in this and indented subclasses are road portions including joint means though the road portion is not clearly identified as a "pavement".

(2) Note. Included in this and indented subclasses is pavement structure with reinforcement structure extending from one pavement portion to another.

(3) Note. Included here is road joint structure, per se, not elsewhere classifiable, either in some other class or higher in this class schedule.
