Secondly, because the non-cured rubber asphalt contains a certain amount of liquid components such as mineral oil and the like, the waterproof material is in a creep state in a short time, the cohesive strength is not enough, the material loses the creep property with the time, and the elongation rate is greatly reduced. Thirdly, the material cannot be constructed under the condition of a wet foundation surface. Fourthly, the main component of the material has poor aging resistance and short service life. In view of the above, there is an urgent need to develop new products for gradual replacement.
