The invention discloses a preparation method of an anti-crack patch for an overlay under a thin asphalt overlay. The modified asphalt comprises the following raw materials in parts by weight: 45 parts of 70 # heavy traffic asphalt, 20 parts of 90 # road asphalt, 15 parts of SBS dry glue, 3 parts of APAO polyolefin, 15 parts of heavy calcium carbonate and 5 parts of coumarone resin. The coumarone resin is C9 petroleum resin, the prepared anti-crack paste for the overlay under the thin asphalt overlay has good dimensional stability and adhesion performance, and an asphalt layer does not slide in an experimental environment at the high temperature of 170 DEG C; the preparation method is simple and easy to implement, and the problems that an existing road and bridge waterproof coiled material is heavy in weight, prone to being pulled up in the paving process and unstable in post-pouring asphalt concrete structure are solved; and the anti-crack paste can be widely popularized and applied, so that the anti-crack performance of the anti-crack paste is improved, and the convenience in use is improved.
本发明公开了一种用于薄层沥青罩面下加铺层用抗裂贴的制备方法。本发明中，包括按照重量份数计的如下原料：70#重交沥青45份，90#道路沥青20份、SBS干胶15份、APAO聚烯烃3份，重钙15份，古马隆树脂5份；所述古马隆树脂为C9石油树脂，制得的薄层沥青罩面下加铺层用抗裂贴,具有良好的尺寸稳定和粘附性能，高温170℃实验环境沥青层无滑动；本发明制备方法简单易行，解决现有道桥防水卷材重量重，摊铺过程容易被拉起来，与后浇筑沥青砼结构不稳定的问题；可广泛推广应用，从而提高了该用抗裂贴的抗裂性能，提高了使用时的便利性。
