Abstract

The invention provides a mixing and laying device of an asphalt mixture for road engineering. The device comprises a measuring mechanism, a material supplementing mechanism and a paving mechanism; the measuring mechanism is located behind the screed of a paver and comprises a screw, the screw is in threaded connection with a nut, and a laser range finder, a camera and a locator are fixed to the side wall of the nut; the material supplementing mechanism comprises a material storage box, the material storage box is in sliding connection with the paver through a sliding assembly, and the transverse moving mechanism drives the material storage box to transversely move; and the paving mechanism comprises a lifting part, an outer shell of the lifting part is fixed to the side wall of the material storage box, the telescopic end of the lifting part is fixedly connected with a supporting frame, a horizontal moving mechanism is fixed to the supporting frame, and a moving part of the horizontal moving mechanism is connected with the roller body to drive the roller body to longitudinally move to flatten asphalt added in the material supplementing area. The paving condition of asphalt can be monitored at any time while the asphalt is paved, materials are supplemented in time after pits appear, and the supplemented materials are flatly paved by utilizing the paving mechanism, so that the paving efficiency is improved.

Description

technical field

[0001] The invention belongs to the technical field of road engineering tools, in particular to a mixing and paving device for asphalt mixture used in road engineering. Background technique

[0002] Asphalt pavement refers to various types of pavement paved with asphalt materials mixed with mineral materials. Asphalt binder improves the ability of paving aggregates to resist road damage from driving and natural factors, making the pavement smooth and less dusty. Permeable and durable, asphalt pavement is the most widely used high-grade pavement in road construction.

[0003] When laying asphalt pavement, the sundries in the base layer of the pavement should be removed first to ensure that the base layer of the pavement is dry and clean. Afterwards, in order to better ensure that the base layer and the surface layer are bonded well, a layer of viscous thickener should be sprayed on the old road surface. Asphalt, the third step is paving the asphalt mixture. ...
