Simultaneous gravel sealing technology from quangongzi's blog

The so-called synchronous gravel seal, is the use of special equipment that is synchronized gravel seal car and bonding materials (modified asphalt or modified emulsified asphalt) simultaneously spread on the road, through natural driving or tire roller rolling Single layer of asphalt gravel wear layer, he is mainly used as a pavement surface layer can also be used for low-grade highway surface construction. The simultaneous gravel seal concentrates the spraying of the binder with the aggregate process in a vehicle at the same time, allowing the gravel particles to come into contact with the sprayed adhesive immediately. At this point, due to hot asphalt or emulsified asphalt flow is better, can be buried at any time deeper into the binder. The simultaneous gravel sealing technology shortens the spacing between the adhesive spray and the aggregate spreading, increases the area of ​​the aggregate particles and the binder, makes it easier to ensure a stable ratio between them, improves the work efficiency, Reduce the equipment cultivation, reducing the construction costs. Asphalt pavement after the treatment of synchronous gravel seal, the road has a good anti-skid performance and impermeability performance, can effectively cure the road lean oil, drop particles, minor cracks, rutting, subsidence and other diseases, mainly for the road Preventive and Reproductive Maintenance The simultaneous gravel sealer is used to synchronize the spraying of the asphalt binder and the spreading of the stone so that there is the most adequate surface contact between the asphalt binder and the aggregate to achieve the maximum between them Bonding of special equipment.Road Repair Equipment - Doan Machinery

Whether for road maintenance or as a transitional pavement, the performance of synchronous gravel seal is significantly better than other methods, thus greatly reducing the road maintenance and repair costs. On the original road disease repair role. After the road surface of the road surface of the small cracks, reticulate, lean oil, oil and so have a good repair effect. Short construction period. Sealing the road can be speed limit open traffic, ease the traffic situation, to ensure the normal use of the road. Construction process is simple, practical, wide range of applications. Reduce road maintenance costs. Compared with the traditional black road maintenance, synchronous gravel seal layer use efficiency is high, unit construction cost is low, can save 40% to 60% of the funds.
