Graded broken stone saturated watertight vibration construction technology
The invention discloses a graded broken stone saturated watertight vibration construction technology. The technology comprises the steps that a lower bearing layer is checked, accepted and finished; carrying out mix proportion design and test on the graded broken stone to determine the mix proportion, the loose paving coefficient and the paving method; measuring and lofting on the lower bearing layer which is accepted and accepted to be qualified; preparing macadam raw materials according to the mix proportion determined by the test, and putting the macadam raw materials into a mixing machine for mixing to obtain a mixture; according to a loose paving coefficient and a paving method determined by a test, the mixture is paved on the surface of the lower bearing layer and then compacted, and the compacting method comprises the steps that static pressing, repairing and leveling and vibration rolling are conducted firstly, then the rolled mixture is fully watered to be saturated, and then rolling is conducted repeatedly till water flows away from gaps, and the graded broken stone layer meets the compaction degree requirement. The graded broken stone can be applied to the airfield pavement base layer, the compaction degree reaches 100%, and meanwhile the surface of the airfield pavement base layer is smooth and dense and free of looseness and segregation.
本发明公开了一种级配碎石饱和水密振实施工工艺，其包括：下承层验收、修整；对级配碎石进行配合比设计和试验，以确定配合比、松铺系数、摊铺方法；在验收合格的下承层上测量放样；按试验确定的配合比准备碎石原料，将碎石原料置于拌和机械中进行拌和得到混合料；按试验确定的松铺系数和摊铺方法，将混合料摊铺在下承层表面，再压实，其中，压实方法包括：先静压，修补找平，再振动碾压，然后对碾压后的混合料充分洒水至饱和，再重复碾压直到水分从空隙中流走，且级配碎石层达到压实度要求。本发明能使级配碎石应用于机场道面基层，压实度达到100％，同时机场道面基层表面平整密实，无松散，无离析。
