A double-layer glass fiber reinforced concrete pavement structure suitable for urban roads

Abstract

The invention discloses a dual-layer glass fiber concrete pavement structure applicable to city roads. The pavement structure comprises a basic layer which is divided into an upper basic layer body and a lower basic layer body; the upper basic layer body is made from lean concrete; the lower basic layer body is made from cement stabilized crushed stone; a cement concrete face layer is laid on the basic layer, and a graded broken stone cushion layer is laid on the lower side of the basic layer; the cement concrete face layer is provided with dual-layer continuous glass fiber ribs and a supporting base, the dual-layer continuous glass fiber ribs are composed of upper-layer continuous longitudinal glass fiber ribs, lower-layer continuous transverse glass fiber ribs and lower-layer continuous longitudinal glass fiber ribs; transverse joints are arranged on the face layer at the interval of 150 m, and a pre-cut seam transversely penetrating a well cover is arranged on the well cover of the face layer; an emulsified asphalt slurry seal modified by styrene butadiene rubber latex is arranged between the upper basic layer body and the lower basic layer body; the basic layer and the face layer are provided with 2-3% road arch cross slopes. The pavement structure can effectively solve the problem that because a water system in a city road is rich or water drainage is not smooth, a pavement structure is seriously damaged in the early stage.

Description

technical field [0001] The invention belongs to the technical field of road engineering and relates to a double-layer glass fiber reinforced concrete pavement structure suitable for urban roads. Background technique [0002] At present, urban roads generally have problems of poor drainage, serious water accumulation on road surfaces and pavement structures, coupled with frequent occurrence of extreme weather events such as torrential rains caused by factors such as urban heat island effect, large and medium-sized cities often suffer from waterlogging, and the existence of water The road surface structure is severely scoured by the action of traffic and driving, which greatly affects the overall strength and stability of the pavement structure, causing serious early damage to urban roads, often causing traffic interruption or congestion due to road maintenance, and even causing traffic accidents. There is an urgent need to improve urban road durability. In addition, many lar...
