Preparation method of reactive normal-temperature asphalt mixture
The invention provides a preparation method of a reactive normal-temperature asphalt mixture, and relates to asphalt preparation. The preparation method of the reactive normal-temperature asphalt mixture comprises the following steps: S1, taking imidazoline and unsaturated fatty acid according to a molar ratio of 0.5: 2.5, and heating the unsaturated fatty acid to 75-80 DEG C; a proper amount of emulsifier is doped into asphalt, so that the viscosity of the asphalt is reduced, and the adhesive force of the asphalt and aggregate is increased, so that the cold patch asphalt mixture can be constructed at normal temperature; water is added to promote the chemical reactant to react with effective components in the emulsifier, the initial strength of a repaired pavement can be improved in a short time, meanwhile, due to volume expansion of a reaction product, gaps in a mixture are effectively filled, the gaps in the mixture are compact and firm, the pavement strength is improved, and due to the fact that the reaction is an exothermic reaction, the pavement strength is improved. The water evaporation is accelerated, the pavement curing time is shortened, and the construction progress is accelerated.
本发明提供一种反应型常温沥青混合料制备方法，涉及沥青制备。该基于一种反应型常温沥青混合料制备方法，包括以下步骤S1.取咪唑啉、不饱和脂肪酸按照摩尔比0.5:2.5，将不饱和脂肪酸加热至75～80℃。通过向沥青中掺入适量的乳化剂，降低沥青的黏度，增加沥青与集料的附着力，使得该种冷补沥青混合料可以在常温下施工，在沥青混合料中掺入化学反应剂，在对路面进行修补时，通过加水促进该种化学反应剂可以与乳化剂中的有效成分进行反应，可在短时间提高修补路面的初始强度，同时反应产物由于体积膨胀，有效填充了混合料内部的空隙，是混合料内部空隙紧致结实，提高了路面强度，由于反应是放热反应，加快了水分蒸发，缩短了路面固化时间，加快了施工进度。
