Embodiment Construction

[0022] The present invention will be described in further detail below by means of specific embodiments:

[0023] The reference signs in the accompanying drawings of the specification include: surface layer 1, second adhesive layer 2, polypropylene cloth 3, first adhesive layer 4, base layer 5, front driven wheel 6, single-row rubber wheel 7.

[0024] The embodiment is basically as shown in the accompanying drawings: the synchronous asphalt-based cloth sealing layer in this scheme includes the second adhesive layer 2, the polypropylene cloth 3 and the first adhesive layer 4 that are sequentially stacked and connected from top to bottom, wherein the first adhesive layer One adhesive layer 4 is connected with the pavement base layer 5 , and the second adhesive layer 2 is connected with the pavement surface layer 1 . The pavement surface layer 1 here can be a cement pavement, an asphalt pavement, a gravel layer, etc., and the pavement base 5 can be a rigid base (cement concrete),...

Abstract

The invention discloses a synchronously-constructed asphalt base cloth sealing layer. The synchronously-constructed asphalt base cloth sealing layer comprises a first bonding layer connected with a base layer, a second bonding layer connected with a surface layer and a piece of polypropylene cloth connected between the first bonding layer and the second bonding layer, and the first bonding layer and the polypropylene cloth are synchronously constructed through a base cloth sealing layer construction vehicle. The synchronously-constructed asphalt base cloth sealing layer can effectively prevent water seepage, delay reflection of base layer cracks and treat base layer top surface cracks, and the characteristics of integrity, continuity, high overload-resisting capacity and the like of a road surface structure are guaranteed; and the base cloth sealing layer construction vehicle can well solve the problem that construction of similar base cloth is not convenient. The synchronously-constructed asphalt base cloth sealing layer is suitable for various road surface structures, and especially suitable for areas where the traffic is heavy, the underground water level is high, the temperature is high and the raining frequency is high, and mountainous and heavy hill areas, and the synchronously-constructed asphalt base cloth sealing layer can further be used as a bonding layer for a cement concrete bridge deck, a white-to-black road surface, an asphalt road surface overlaying layer and the like, and a bottom layer of a synchronously-constructed asphalt crushed stone sealing layer.

Description

technical field [0001] The invention relates to the field of road paving, in particular to a synchronous asphalt base cloth sealing layer. Background technique [0002] The pavement structure layer refers to the paving layers that make up the pavement. According to their layers and functions, they mainly include the surface layer, base layer and cushion layer. Among them, the surface layer is located at the top of the entire pavement structure. It directly bears the vertical force and horizontal force of the driving load, as well as the vacuum suction generated behind the vehicle body. levels. The base layer is located below the surface course and above the cushion or subgrade. The base layer mainly bears the vertical force of the wheel transmitted by the surface layer and spreads it to the cushion and soil foundation. The base layer may also be eroded by water seepage from the surface layer and groundwater. Not all pavement structures need to be equipped with a cushion. ...
