42、压和终压。初压由于混合料厚度达 20cm，摊铺后混合料仍很松散，呈半流动状态，直接振压或重型碾压，容易产生推移和波浪。我们采用先由轮胎压路机静压12 遍，使其初步密实，压实度达到80%85%左右。复压在初压完成后，用16t 振动压路机呈梯形进行弱振压12 遍，用 22t 振动压路机呈梯形进行振压23 遍，直至压实度符合要求。终压复压结束后，立即用三钢轮压路机进行终压。目的是消除轮迹，进一步密实。压路机要紧跟摊铺机，呈梯形逐渐向前推进，形成流水作业。(4)碾压注意事项压路机不得停在未压实的基层上，并不准在其上急刹车、急转弯和调头。振动压路机前进、后退换档时，应先停振再换档；若需停机时，应先停振再

43、停机。终压前应检测一次标高，若发现高程超过规定时，应用平地机刮至规定值，再整平碾压。养生(1)该基层成活后养护工作至关重要，石灰粉煤灰基层表面易风干，如果养护跟不上，不但影响强度增长，而且表层松散扬尘，所以碾压完成后第二天开始养生，采用洒水车洒水养生的方法。每天洒水至少六次以上或视气候条件而定，应始终保持表层潮湿。养生期不宜少于7 天。(2)在养生期间，除洒水车外封闭交通，在已经成活的二灰基层地段禁止各种车辆通行，并进行封闭管理。四、质量标准二灰碎石路面基层质量检查表项目要求值检验频率检验方法|精.|品.|可.|编.|辑.|学.|习.|资.|料.*|*|*|*|欢.|迎.|下.|载.第 7 页
