Abstract

The invention discloses a continuous reinforced concrete pavement structure suitable for an urban road. The pavement structure comprises a base layer which is divided into an upper base layer body and a lower base layer body. The upper base layer body is made of lean concrete. The lower base layer body is made of cement stabilized macadam. The base layer is paved with a cement concrete pavement layer, and the position under the base layer is paved with a graded broken stone hardcore. The cement concrete pavement layer is provided with double-layer continuous rebars and supporting bases. The double-layer continuous rebars comprise the upper-layer continuous longitudinal rebars, the lower-layer continuous transverse rabars and the lower-layer continuous longitudinal rebars. Transverse joints are arranged on the pavement layer at intervals of 150 m. A pre-cutting joint transversely penetrating through a well cover is arranged at the well cover on the pavement layer. A emulsified asphalt slurry seal modified through styrene butadiene rubber latex is arranged between the upper base layer body and the lower base layer body. The base layer and the pavement layer are provided with 2%-3% crown slopes. According to the continuous reinforced concrete pavement structure suitable for the urban road, the problem that in the urban road, the pavement structure is severely damaged early due to abundant water systems or impeded drainage can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of road engineering and relates to a continuously 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 large and mediu...
