高粘改性乳化沥青碎石封层技术是利用同步碎石封层车将粘结料(高粘改性乳化沥青、纤维和改性乳化沥青组合)与洁净干燥的单一粒径防滑料喷酒在路面上，保证高粘改性乳化沥青与防滑料在最短的时间内完成结合，并在外荷载(胶轮压路机或自然行车)作用下不断形成强度的一种路面养护技术。
High viscosity modified emulsified asphalt macadam sealing technology is to use synchronous macadam sealing vehicle to spray the binder (combination of high viscosity modified emulsified asphalt, fiber and modified emulsified asphalt) and clean and dry single particle anti-skid material on the road surface, so as to ensure the combination of high viscosity modified emulsified asphalt and anti-skid material in the shortest time, and keep forming under the action of external load (rubber wheel roller or natural driving) A kind of pavement maintenance technology with high strength.
