Production and preparation method of ultrathin anti-skid wearing layer
The invention provides a method for producing and preparing an ultrathin anti-skid wearing layer, which comprises the following steps of: designing the ultrathin anti-skid wearing layer into a skeleton structure according to the volume composition principle of a mixture, filling gaps with mineral powder and asphalt by adopting an optimal embedding and extruding structure and 0-3mm of coarse particles, establishing space volume composition parameters of the mixture, and expressing the states of asphalt-coated aggregate, fiber and mineral powder through a specific surface area, so as to obtain the ultrathin anti-skid wearing layer. And establishing an under-membrane relational expression of the asphalt with the optimal structure, and accurately determining a proportional relation among 5-10mm, 3-5mm, 0-3mm and mineral powder by taking parameters such as void ratio, asphalt-aggregate ratio, fiber and the like as control input quantities. According to the invention, the void ratio is used as a pre-control index, so that the asphalt mixture has the characteristic of large void, the purposes of skid resistance and noise reduction are achieved, the use amount of fibers and asphalt is controlled, the thickness of an asphalt film and the proportion of structural asphalt are in a better state, and the bonding strength between aggregates is improved, so that the asphalt mixture has higher durability.
本发明提供一种超薄抗滑磨耗层生产制备方法，混合料体积构成原理，将其设计成骨架结构，粗颗粒采用最佳嵌挤结构，0～3mm、矿粉、沥青填充空隙，建立起混合料空间体积构成参数，通过比表面积对沥青裹附集料、纤维、矿粉状态进行表述，并建立最佳结构沥青膜下关系式，通过空隙率、油石比、纤维等参数为控制输入量，精准的确定5～10mm、3～5mm、0～3mm以及矿粉的比例关系。本发明将空隙率作为预控指标，使得沥青混合料具有大空隙的特性，起到抗滑降噪目的，纤维、沥青用量加以控制，使得沥青膜厚度、结构沥青比例处于较优状态，增加集料之间粘结强度，从而使沥青混合料具有较高的耐久性。
