Description
Technical Field
The invention belongs to the technical field of road engineering, and particularly relates to a composite slurry capable of being applied to rapidly melting snow and ice under the microwave heating of asphalt concrete and an application method.
Background
Along with the deep development of industrialization, the problem of environmental pollution is more and more prominent, and along with the world has entered the era of intelligent rapid development, the demand for intelligent road surface is more and more urgent, and the development of green intelligent environment-friendly microwave heating bituminous pavement is imperative. The current road operation and maintenance process (such as road deicing and the like) consumes a large amount of energy and is likely to cause great pollution. The traditional manual deicing method has the problems of low deicing efficiency, high manpower and material cost, potential safety hazards and the like; the way of deicing by chemical agents has the problem of environmental pollution. Therefore, a new and proper snow and ice melting method is found, and the method has important practical significance for solving the problem of ice and snow on the asphalt concrete pavement in the cold region.
Therefore, numerous scholars try to realize snow melting and deicing through a pavement heating mode by carrying out microwave heating on the asphalt pavement. However, because the microwave heating performance of common asphalt concrete is poor, the microwave absorption performance of the asphalt concrete is often improved by adding microwave reinforcing materials into the asphalt concrete. The existing microwave absorbing materials are mainly powder materials or fiber materials, and the reinforcing mode is mainly that the microwave absorbing materials are directly added into asphalt concrete in the form of external additives. However, the microwave heating effect of the asphalt concrete is improved compared with that of the common asphalt concrete due to the small mixing amount, but the improvement effect is not obvious.
In addition, the asphalt pavement in China usually has the phenomenon of surface structure abrasion consumption shortly after service, so that the anti-skid performance is rapidly attenuated, and the running safety of vehicles and the service level of roads are seriously influenced. For the early diseases with good structural strength and only needing to recover the surface function, preventive maintenance technologies such as sand-containing fog sealing, micro-surfacing and the like are generally adopted for treatment. However, in most of the prior sand-containing fog sealing layer technologies in China, due to the fact that the bonding strength of the cementing material is not enough, the phenomena of abrasion, peeling and the like are easy to occur when the sealing material is applied to southern areas with much rainwater, and the durability is not enough.
