These mixes also conform well to surface irregularities during compaction, thereby improving smoothness with less layer thickness than coarser mixes. For surface courses under light to moderate traffic, properly designed 4.75 and 9.5-Type I mixes are generally more suitable and more economical than the high-volume mixes, and their use in these
