Study of Strong Interlocked Skeleton Dense Gradation for Cement-Stabilized Macadam
In order to improving the performance of Cement-stabilized Macadam (CSM), analyzing the influences of its composition structure on performance, and then putting forward the gradation design principles and strong interlocked framework dense gradation (SISDG), laboratory test was adopted to verify its road performance. Result shows that CSM has the feature of the amount of aggregate above 9.5 mm, below 4.75 mm and 0.075 mm are more, while the amount of aggregate 4.75-9.5 mm is less, and the California Bearing Ratio (CBR) value of mineral aggregate with SISDG is increased by 8~14% comparing with mineral aggregate with the framework dense-graded (DSDG) presented in Design Specifications of Highway Asphalt Pavement (JTG D50-2006) gradation. Compared with CSM with DSDG, 28d unconfined compressive strength (UCS), ultimate UCS and splitting strength of CSM with SISDG are respectively increased by 6~12%, 8~20% and 8~15%.
