Information of gyratory compaction densification curve of asphalt mixture and its application;

Study on the SGC and inter-lock analysis in improvement of stage filling;

Based on the advantage that the Superpave gyratory compactor(SGC) could character- ize the in-situ pavement compaction,and its operation system is convenient for data acquisition,the gyratory compaction method is adopted for the proportioning design of SMA 13.

The crumb rubber-asphalt concrete with different fineness and different blended amounts, is studied by laboratory Marshall test, gyratory compactor test and wheel tracking test in this paper.

The compaction curve of mud formation may reflect the law of hydrocarbon migration,and the poorly-compacted interval of mudformation usually corresponds to low ve.

The results obtained from the compactional studies by means of the microscope observation of sections,a compaction curve of porosity vs depth and the simulating experiments of carbonate rocks in Ordos basin at high-temperature and-pressure suggest the compaction,especially mechanical compaction exists in the carbonate rocks.

By utilizing three displacement sensors and corresponding algorithms,the accurate detecting and positioning of angle of gyration are realized.
