     Study on the Compaction Technology of Gap Semi-open Gradation Asphalt        Mixture Used to Overlay the Cement Pavement

WANG Guo-pei, HUANG Lv-qun, HAN Hai-feng, et al

Abstract: In this paper, two kinds of compaction technologies used for the gap semi-open gradation (GSOG) asphalt mixture are introduced. A new process control method of the compaction degree for this mixture is given. The two compacted effects of the mixtures are analyzed on the basis of the practice of  the trial road, and the kernel of the compaction technologies which is adequate for the GSOG asphalt mixtures is summarized.

Key words: gap semi-open gradation (GSOG); asphalt mixture; overlay; compaction technology
