沥青砼转运—摊铺工艺在河龙高速公路的试验研究

Experimental Study of Asphalt MTP in Helong Express Highway

通过在河龙高速公路沥青路面摊铺过程中采用摊铺机直接摊铺作业和采用转运—摊铺工艺(转运车-摊铺机联合施工)作业的试验路面效果对比,实验研究结果表明采用转运—摊铺施工工艺是消除温度离析、减轻骨料离析、提高路面平整度的有效手段。

It appears that asphalt mixture transfer and paverment（MTP） can eliminate temperature differentials and reduce aggregate segregations during HMA pavement by the way of contrasting the surfacing phenomena between the direct paver pavement and the MTP. So the MTP can result in the satisfied effect in highway construction.
