27、astic asphalt (general definition) dense mass consisting of chippings, and/or sand, and/or limestone fine aggregate, and/or filler and bitumen which may contain additives The mineral aggregate is composed to be of low void content. The binder content is so adjusted to the void content of the mineral
28、 aggregate that the voids are completely filled and a slight excess of binder may be available. Mastic asphalt is pourable and able to be spread in his hot condition. It requires no compaction on placement. 3.1.2 fine aggregate mastic asphalt grade of mastic asphalt consisting of filler and/or limes
