Mud jacking technology of cement concrete pavement use fine sand substitute partial fly ash

探讨水泥混凝土路面悬空病害板块的压浆处理工艺中,用部分海砂取代粉煤灰,在掺用膨胀剂的基础上填加早强剂的施工工艺,从而提高了强度,降低了造价,并且达到了提前开放交通的目的。

In view of the void diseases beneath slab of cement concrete pavement mud jacking technology is introduced.Sea sand is used to substitute partial fly ash.Early strength accelerator is also used to improve strength and reduce cost to reduce limit time for reconstruction of existing line.
