Modified emulsified asphalt cementing material as well as preparation method and application thereof
The invention discloses a modified emulsified asphalt cementing material which comprises the following components in percentage by mass: 80-90% of matrix emulsified asphalt and 5-25% of a tackifying and reinforcing modifier, and the tackifying and reinforcing modifier is a mixture of acrylic emulsion and bentonite. The invention also discloses a preparation method and application of the modified emulsified asphalt cementing material. According to the modified emulsified asphalt cementing material provided by the invention, the tackifying and reinforcing modifier composed of the acrylic emulsion and the bentonite is introduced to reinforce and modify the matrix emulsified asphalt, so that the modified emulsified asphalt cementing material can better resist permeation and damage of water, and the service life of a road is prolonged; and secondly, the acrylic emulsion in the tackifying and enhancing modifier can form a cross-linked network structure, so that the structural stability of the emulsified asphalt cement is enhanced, the aging speed of asphalt is slowed down, the friction coefficient of an asphalt pavement is increased, and the effects of resisting wear caused by vehicles and weather and resisting skid of the modified emulsified asphalt cement are effectively improved.
本发明公开了一种改性乳化沥青胶结料，以质量百分比计其包括如下组分：基质乳化沥青80‑90％和增粘增强改性剂5‑25％，所述增粘增强改性剂的为丙烯酸乳液和膨润土的混合物。本发明还公开了该改性乳化沥青胶结料的制备方法和应用。本申请所提供的改性乳化沥青胶结料，通过引入丙烯酸乳液和膨润土组成的增粘增强改性剂对基质乳化沥青进行增强改性，使得改性后的乳化沥青胶结料能更好地抵抗水的渗透和破坏，延长道路使用寿命；其次，增粘增强改性剂中的丙烯酸乳液能够形成交联网络结构，进而增强乳化沥青胶结料的结构稳定性，减缓沥青的老化速度，增加沥青路面的摩擦系数，有效提高了该改性乳化沥青胶结料的抗车辆和气候引起的磨损及抗滑效果。
