Abstract:
The aggregate is easily broken and its compacted state don't coincide with practice when the Marshall compaction method is adopted in compacting porous asphalt concrete(PAC)with Chinese Technical Standards Technology Specification for Constructing Highway Asphalt Pavement. So this paper put forward molding the PAC specimen with SGC, furthermore, induct the concept of locking point for ascertain the optimal times of SGC, compared the volume performance for the two kinds of specimen with different molding methods. The compaction characteristics were analyzed according to the data recorded in the process of SGC. The results showed that: it is better to use the SGC method for molding PAC specimen; when the times of SGC is about 50, PAC will form the steady framework structure, and at this time, the compacting work and volume performance of the specimen between the two kinds of molding methods are quite similar. PAC with good gradation has well compaction characteristics and the ability of resistance for deformation after opening to traffic. 6 tabs, 5 figs, 13 refs.
