7、s:3.1.1 The types of surface treatments covered by thispractice are as follows:3.1.2 multiple-surface treatmenta wearing surface com-posed of bituminous material and aggregate,in which coarseraggregate is placed uniformly over an initial application ofbituminous material and followed by one or more
8、subsequentapplications of bituminous material and smaller aggregate.3.1.2.1 DiscussionGenerally,the designated maximumsize of the smaller aggregate is one half that of the aggregateused in the preceding application.Each application of aggre-gate is placed uniformly in a single layer,the thickness of
