为探究水泥混凝土路面滑模施工过程中,各施工工序对路面平整度的影响,在3个路面改造工程中,共选择35个试验段,分别使用澳大利亚ARRB G2手推式精密断面仪,实时检测水泥混凝土路面滑模施工中不同基层与履带行走位平整度时相应路面、不同基准线桩距路面、有无人工3m直尺精平路面以及切缝与刻槽前后路面的国际平整度指数。主要结论如下:基层和履带行走位平整度以及切缝及刻槽工序对路面平整度没有影响;基准线桩距越小面层平整度越好,5m桩优于10m桩;人工3m直尺精平对路面平整度起破坏作用,精平次数越多,路面平整度越差。
In order to explore the impact of construction process on the road surface roughness in the process of sliding formwork construction of cement concrete pavement, a total of 35 test sections were selected for the three pavement reconstruction projects. The Australian ARRB G2 hand push precision section instrument was used to detect Cement concrete pavement sliding mode construction of different grassroots level and crawler walking flatness of the corresponding pavement, different baseline piles pavement, with or without artificial 3m straightedge precision pavement and kerf before and after cutting the international roughness index. The main conclusions are as follows: The leveling of the grassroots and crawler track and the effect of cutting and grooving processes have no effect on the road surface roughness; the smaller the basement pile spacing, the better the surface roughness, 5m pile better than 10m pile; Flat on the road roughness play a destructive role, the more flat, the worse the road surface roughness.
