Embodiment 1

[0029] A new environment-friendly modifier for asphalt and asphalt mixture, which is composed of the following components in parts by weight: 50 parts of polymer carbon-containing compound, 10 parts of polymer resin, and 5 parts of organic acid.

[0030] In the preparation method of the above-mentioned modifier, the organic acid is heated to about 120° C., then the polymer resin is added, stirred for 15-30 minutes, and then the polymer carbon-containing compound is added and stirred evenly.

[0031] The wet construction process of the above-mentioned modifier is as follows: heat the base asphalt to 150-160°C, then add the above-mentioned modifier, the amount of the modifier added is 10%-20% of the asphalt mass, the temperature is 160°C, stir 30-60min, that's all.

Embodiment 2

[0033] A new type of environment-friendly asphalt and asphalt mixture modifier, which is composed of the following components in parts by weight: 80 parts of polymer carbon-containing compounds, 25 parts of polymer resin, 15 parts of organic acid, and the organic acid is heated to 120 ℃ Then add polymer resin, stir for 15-30 minutes, then add polymer carbon-containing compound and stir evenly. The above-mentioned modifiers are in the form of tan particles.

[0034] The construction method of above-mentioned environment-friendly asphalt and asphalt mixture modifier, comprises the following steps:

[0035] 1) The dry construction process is as follows: After the aggregates of various specifications are heated, the temperature of the aggregates is controlled at 175-185°C, and put into the mixing tank;

[0036] 2) The above-mentioned modifier is delayed by two seconds, and is put into the mixing tank together with the aggregate by manual feeding or air-feeding feeder, and then mi...

Abstract

The invention discloses a novel environment-friendly asphalt and asphalt mixture modifier, comprising, by weight, 50-80 parts of a macromolecular carbon-containing compound, 10-25 parts of macromolecular resin, and 5-15 parts of an organic acid. The invention also discloses a preparation method and construction method of the modifier. The invention provides the novel multifunctional environment-friendly asphalt and asphalt mixture modifier that may replace SBS (styrene-butadiene-styrene) modifiers; the preparation and application processes of the modifier are simple and environmentally friendly, and the modifier has stable properties, long shelf life and low energy consumption and is applicable to various asphalt mixtures. The modifier can ensure that various pavement performances of the asphalt mixtures are not lower than those of SBS modified asphalt, the production process is simple, and energy saving, emission reduction and pollution reduction are truly achieved.

Description

technical field [0001] The invention relates to the field of road engineering, in particular to a novel environment-friendly asphalt and asphalt mixture modifier which can replace the SBS modifier in road engineering construction. Background technique [0002] SBS modifier is used to modify base asphalt, and the asphalt mixture produced by using SBS modified asphalt has excellent road performance. At present, it is widely used in the paving of asphalt pavement, but its shortcomings are gradually reflected. [0003] The main production process of SBS is: heating base asphalt to 170-180°C, then adding SBS modifier, stirring for 15-30 minutes, so that SBS modifier is evenly distributed in base asphalt. Then, the mixture of base asphalt and modifier with uniform modifier distribution is sheared at a high temperature of about 180-185°C for 20-40 minutes. The processing temperature of SBS modified asphalt is high, the process is cumbersome, and the cost is high; at the same time...
