Abstract

The invention especially relates to a seal coat spreading facility and spreading method, belonging to the technical field of road construction machinery. The seal coat spreading facility comprises a car body and is characterized in that a water spraying device, an interfacial agent sprinkling device, an asphalt sprinkling device, a stone spreading device and a protective agent sprinkling device are arranged on the car body. The spreading method comprises the following steps: successively spraying water, an interfacial agent and a first layer of asphalt onto a pavement; spreading stone and rolling the stone; sprinkling a second layer or multiple layers of asphalt onto the stone; and sprinkling a protective agent onto the second layer of asphalt. The invention has the beneficial effects that the spreading facility and spreading method have good versatility, can realize synchronous implementation of a plurality of construction steps, guarantee stable soundness and anti-skid capability of the pavement, are accurate in control and uniform in spreading and ensure beautiful appearance of the pavement; and the spreading facility is simple in structure, convenient to use, easy to maintain and adaptive to pavements of various widths, so seal coat construction efficiency and quality are substantially improved.

Description

[0001] (1) Technical field [0002] The invention belongs to the technical field of road construction machinery, and in particular relates to a sealing layer spreading equipment and a spreading method. [0003] (2) Background technology [0004] At present, the pavement surface treatment technologies mainly include synchronous gravel seal, fog seal and sand-containing fog seal, etc. [0005] During the road construction process, the asphalt pavement is sealed with crushed stone simultaneously, which can have better anti-skid and anti-seepage performance. Synchronous crushed stone seal layer technology is to spread crushed stones and bonding materials on the road surface simultaneously, and form a single layer of asphalt crushed stone wear layer through natural driving and rolling, which is used as the surface layer of the road surface. [0006] Due to the increase of traffic flow and overloaded transportation, the road surface will have rutting, wrapping, cracking, smooth surf...
