For the settlement of shrinkage cracks of semi-rigid base,the micro-crack technology of cement-stabilized macadam base in our country has been at the early stage of research and development. Through the study on the relationship between vibration time of the compaction tester and reducing percentage of unconfined compressive strength,the relationship between the degree of micro-crack and vibration time was determined; the micro-crack width value on the specimen surface after micro-crack was observed and rea...
