Microcosmic analysis of Cement-stabilized Macadam Base in anti-crack

ZHOU Cheng-xi

Abstract : In the paper , rely on the south highway of the Runyang Yangtze River Bridge,and through scanning electronic microscopic photo of cement-stabilized macadam base course, studied crack mechanism of the microstructure and the physica-mechanical characteristics as well as the influernce of cement-stabilized macadam base course,and about some fly-ash,additons etc.

Key word : cement-stabilized macadam base；anti-crack mechanism；Microcosmic analysis
