Pouring and blade coating type semi-flexible pavement and construction method
The invention discloses a pouring and blade coating type semi-flexible pavement, which is characterized in that a large-gap matrix asphalt mixture is used for paving the pavement, internal slurry is used for pouring the pavement, and mortar is blade-coated on the surface. The invention also discloses a construction method of the pavement. The construction method comprises the following steps: paving the large-gap asphalt mixture pavement on a construction road section; pouring internal slurry into the paved large-gap asphalt mixture; blade-coating mortar on the surface of the pavement; and opening traffic after pavement maintenance. According to the method, the problems of early-stage dust raising, too high dyeing cost and uneven surface structure caused by pouring single-variety slurry to the road surface in the traditional pouring type semi-flexible pavement are solved. The surface mortar and the internal slurry are bonded before initial setting to form a whole, and the surface of the mortar almost has no floating ash, so that no dust is raised after traffic is opened. If dyeing needs exist, only the surface mortar needs to be dyed, and the dyeing cost is reduced by 90% or above. The mortar does not flow and is not sensitive to the slope of the road surface, and the surface structure can be comprehensive and uniform.
本发明公开了一种灌注+刮涂式半柔性路面，大空隙母体沥青混合料摊铺路面，内部浆液灌注路面，表面刮涂胶砂。同时公开了该路面的施工方法：在施工路段摊铺大空隙沥青混合料路面；在摊铺好的大空隙沥青混合料中灌注内部浆液；路面的表面刮涂胶砂；路面养生后开放交通。本发明解决了传统灌注式半柔性路面灌注单一品种浆液至路表导致的早期扬尘问题、染色成本过高、表面构造不均匀的问题。表面胶砂与内部浆液初凝前粘结，形成整体，胶砂表面几乎无浮灰，因此开放交通后无扬尘。若有染色需求，仅需对表面胶砂进行染色，染色成本降低90%以上。胶砂不流淌，对路面坡度不敏感，且表面构造能够实现全面均匀。
