Description

Method for fine surface treatment of anti-freezing asphalt pavement
Technical Field
The invention belongs to the technical field of road engineering, and particularly relates to a fine surface treatment method for an anti-freezing asphalt pavement.
Background
The safety of road driving in winter is an important issue of general concern at home and abroad. In winter, snow and ice on the surface of the road greatly reduce the skid resistance of the road, so that the traffic capacity of the road is seriously weakened, the running safety of vehicles is seriously threatened, and serious traffic accidents are easily induced. Usually, when the temperature is lower than 0 ℃, the ice-condensation on the pavement, i.e. a layer of thin ice adhered on the surface of the pavement, occurs. At present, the traditional snow-melting and deicing method has the defects of passiveness, low efficiency, damage to road surfaces, environmental pollution and the like, for example, the spread of deicing salt is the method which is most used for deicing road surfaces, but chloride ions contained in the deicing salt can permeate into road surface structures or flow into surrounding fields along with molten water, so that the corrosion is caused to road surface materials, the service performance of the road surfaces is influenced, and the surrounding environment is polluted. Manual or mechanical deicing has high energy consumption and low efficiency, easily damages road traffic facilities, and is difficult to recover traffic in time.
Chinese patent CN101787216A discloses an anticoagulant ice agent for asphalt concrete gravel seal and a preparation method thereof, and the anticoagulant ice agent is prepared from the following materials in parts by mass: 85-95 parts of chloride, 2-7 parts of calcium carbonate, 2-5 parts of silicon dioxide, 2-5 parts of carbon black, 6-10 parts of stearic acid and 10-20 parts of calcium stearate. The material can reduce the freezing point of the pavement, but the reduction degree is limited, and the material cannot be widely applied to northern areas.
The invention provides a salt-storage slow-release snow-melting deicing agent and a preparation method thereof, which comprises the following steps: firstly, respectively preparing an anti-freezing chlorine salt saturated solution and a nano-silica modified diatomite suspension, then dropwise adding the anti-freezing chlorine salt saturated solution into the nano-silica modified diatomite suspension, stirring, vacuum filtering, drying and crushing to obtain a slow-release inorganic salt; preparing a polymer monomer solution, finally sequentially adding the slow-release inorganic salt, isopropanol or propylene glycol methyl ether solution into a flask, putting the flask into an oil bath, uniformly stirring, adding a mixed solution of the polymer monomer solution and KH570 and AIBN, continuously stirring, reducing the temperature, adding triethylamine into the flask, stirring, and adding water to obtain the salt-storage slow-release snow-melting deicing agent. The snow melting substance in the salt-storage slow-release snow melting deicing agent prepared by the patent is not limited by temperature control molecules, and the snow melting substance is long in release time and high in ice melting amount. However, the measure belongs to a passive control technology, and the measure needs to be paved after the road is frozen, so that the smoothness of the road cannot be ensured at any time, and the safety of the road can be maintained.
