Embodiment Construction

[0019] The present invention is further described below.

[0020] The rubber powder is made by mixing rubber powders of 10 mesh, 20 mesh, 40 mesh, 60 mesh and 80 mesh respectively. Among them, 80-mesh rubber powder accounts for the majority, and the rest account for a small part. The specific ratio is determined according to the performance index of the base asphalt and the specific requirements of the construction project for the modified asphalt. Experiments can be carried out first to obtain a feasible ratio. The rubber powder can adopt waste tire rubber powder, inner tube rubber powder, miscellaneous rubber powder or natural rubber powder.

[0021] The specific ratio of each raw material in the asphalt modifier of the present invention can be tested according to the performance index of the base asphalt and the requirements of the construction project for the modified asphalt, and an appropriate ratio can be obtained within the above ratio range.

[0022] The softening ...

Abstract

The present invention is one kind of asphalt modifier, and belongs to the field of asphalt modifying assistant. The asphalt modifier is compounded with rubber powder, softening agent, activating agent, composite Al-Ti coupling agent, ammonium fluosilicate, creosote oil and light calcium carbonate in certain weight proportion. When used, it is mixed to asphalt and can improve the high and low temperature performance of asphalt obviously and make asphalt no melting down in the temperature up to 80 deg.c and no cracking in the temperature as low as -35 deg.c.

Description

technical field [0001] The invention provides an auxiliary agent for asphalt modification. Background technique [0002] Modified asphalt refers to adding rubber, resin, high molecular polymer, ground rubber powder or other fillers and other external additives (modifiers) to asphalt, or taking measures such as mild oxidation of asphalt to make the asphalt Asphalt binder made by improving the properties of asphalt or asphalt mixture. The asphalt modifier refers to the natural or artificial organic or inorganic materials added to asphalt or asphalt mixture. It should be melted and dispersed in asphalt, which can improve or enhance the performance of asphalt pavement materials, and react with asphalt or Wrapped on the aggregate surface. [0003] The modified asphalt with asphalt modifier should have the following characteristics: good high temperature stability; better low temperature crack resistance and anti-reflection crack ability; enhanced adhes...
