General process used by the road, will inevitably produce such as cracks, pockmarked face and loose, pits, settlement, rutting, peeling, weeping, bite side, obstruct package, slippery, wave, Kiu culvert top jumping surface damage such pavement disease, if not timely processing of the cure, not only affect road capacity and beautiful and driving comfort, and easy to extend the structural damage caused by road and shorten the life of the pavement, and accelerate the road either in part or into a piece of damage, and ultimately loss to the roadbed , so a good job of road cleaning, small accomplishment at the same time, preventive maintenance is essential, in particular, the arrival of spring on the road gradually, equipment, technologies and processes which can not be ignored. Spring is the highway a variety of disease-prone period, just after the winter's severe environmental challenges, such as temperatures plummeted, frozen, could easily lead to stress and road damage of the asphalt mixture for the conservation of the road environment temperature is too high or the temperature is too low the effects of construction and construction process requirements more stringent, so in general the spring and autumn is the best time to conservation. Spring is a rainy season of frozen roadbed the upper accumulation of water caused by the road flatulence and cracking, the spring melt in the role of driving under the Frothing subgrade Frothing will inevitably lead to the destruction of the road. For preventive road maintenance, the use of ultra-surfacing and micro surfacing equipment can effectively achieve the effect of preventive maintenance, ultra-surfacing technology is a new fast paving the road surface processing nearly two years before from abroad technology, combined with high-performance ultra fast Pavement seal surfacing equipment, new materials and pavement maintenance (ultra-surfacing material), municipal, highway, high-speed set up with ordinary asphalt pavement, pavement surface road early conservation processing it paving the ultra-thin protective layer of special material, allows the road to effectively achieve a waterproof effect, extend the life of reason, the ultra-surfacing paver construction speed of up to 2-3 kilometers per hour, 1-2 hours after construction open to traffic, after construction, waterproof layer for the road, reducing road dust, increase contrast, improve the life of the pavement surface, improve drainage efficiency, road surface appearance after construction, to improve the road the overall image. With its high quality products such as China impact crusher, Rock crushing plant, China cone crusher, Ore beneficiation, Hammer crusher, Henan Hongxing mining machinery Co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.
