Abstract of  CN105778533 (A):

The invention discloses a high-permeability composite high-molecular polymer hot-melt crack filling material. The high-permeability composite high-molecular polymer hot-melt crack filling material is prepared from the following raw materials in parts by mass: 45-60 parts of petroleum asphalt, 3-6 parts of modifying agent, 17-22 parts of stabilizer, 4-10 parts of rubber powder, 4-6 parts of petroleum resin, 6-9 parts of filler and 1-3 parts of reclaiming agent, wherein the stabilizer is prepared from the following raw materials in parts by mass: 79-90 parts of plasticizer, 10-21 parts of diluting agent and 3-5 parts of high-molecular-weight GW-944. The invention further discloses a preparation method of the material. Since the plasticizer is used, the construction performance of the crack filling material is improved; the diluting agent is added in the making process of the crack filling material, so that the liquidity of an asphalt pavement hot-melt crack filling adhesive is enhanced; the crack filling material permeates into pavement cracks well, and an aged asphalt material is activated, so that the phenomenon of separation of the crack filling material from the cracks is reduced; the low-cost filler and used tire rubber powder are used in the crack filling material, so that the cost can be saved, and the compactness of the crack filling material is enhanced.
