Surfactant type asphalt modifier, modified foamed asphalt recycled concrete and preparation method
The invention relates to a surfactant type asphalt modifier, modified foamed asphalt recycled concrete and a preparation method, and aims to improve the foaming performance of asphalt, enable most of asphalt to meet the use requirements of regeneration engineering and solve the problems of difficulty in selection of asphalt raw materials and high cost. By improving the foaming performance of the asphalt and promoting bonding and wrapping of the asphalt and the aggregate, the overall deformation resistance and water damage resistance of the recycled mixture are improved, early diseases of the recycled pavement are reduced, the service life is prolonged, and the cost of the whole life cycle is reduced.
本发明涉及一种表面活性剂型沥青改性剂、改性泡沫沥青再生混凝土及制备方法，改善沥青发泡性能，使得大多数沥青满足再生工程使用要求，解决沥青原材选择难和成本高问题；通过改善沥青发泡性能，促进沥青与集料粘结和裹腹，实现提高再生混合料的整体抗变形能力和抗水损坏性能，减少再生路面早期病害，延长使用寿命，降低全寿命周期成本。
