Abstract

The invention discloses a waste asphalt mixture normal-temperature regeneration modifying agent and a preparation method thereof. Particularly, the waste asphalt mixture normal-temperature regeneration modifying agent comprises the following components in parts by weight: 0-30 part of rubber oil, 30-60 parts of light distillates, 5-10 parts of a polymer, 2-5 parts of a crosslinking agent and 1-5 parts of a surfactant. The regeneration modifying agent is used for producing a regenerative asphalt mixture; the RAP blending rate is high; the blending temperature is low; and the pavement performance of the regenerative asphalt mixture is good.

Description

technical field

[0001] The invention relates to the field of road engineering materials, in particular to a normal-temperature regeneration modifier for waste asphalt mixture and a preparation method thereof. Background technique

[0002] With the vigorous development of highway construction in my country, the traffic volume continues to grow. Many asphalt pavements built earlier in our country have been overwhelmed by the heavy traffic pressure. According to the design life and actual use of these pavements, many high-grade highways have been Entering or approaching the overhaul period. It is estimated that about 12% of asphalt pavement will need to be repaired every year from now on. At the same time, due to the continuous improvement of the high-grade kilometer capacity requirements of various resource-rich provinces, my country has successively carried out a certain number of high-grade highway reconstruction and widening projects in recent years.
