| 摘 要： | 孟营高速公路上面层为SUP型沥青混凝土路面,因而对路面基层裂缝的防治提出了更高的要求。骨架密实性水泥稳定级配碎石结构具有后期强度高、裂缝少等优点,但其碎石含量大,在拌和、运输、摊铺等环节中容易离析。

| Abstract: | The upper surface layer of Mengjiawan-Yingpanshui Expressway is SUP-typed asphalt concrete pavement,therefore the higher requirement is proposed to preventing and controlling the cracks on base layer of pavement.Dense framework-typed cement stabilized graded broken stone structure has advantages of high strength and little cracks in the late stage,but its content of broken stone is so large that segregation easily occ-urs during mixing,transportation and paving process. |

| Keywords: | dense framework type cement stabilized broken stone construction technology quality control |
