12.In penetration macadam pavement construction, when is the bitumen applied?

It is sprayed after the aggregates have been laid and compactedIt is mixed with the aggregates prior to spreadingIt is sprayed before placing and compacting the aggregatesNone of the given choices

13.During highway construction, where does the rolling process typically begin?

At the edges moving toward the middleFrom the center moving outward to the edgesStarting from one edge and moving to the opposite edgeAny of the methods mentioned above

14.In water-bound macadam roads, how does the shoulder camber compare to the pavement's cross slope?

It matches the cross slope of the pavementIt is smaller than the pavement's cross slopeIt exceeds the cross slope of the pavementIt is flat with no slope
