Embodiment 1

[0014] The asphalt modifier is composed of the following components in the following parts by weight:

[0015] Bituminous mixture: sodium dodecylbenzenesulfonate: furan resin: water: = 30:20:5:80.

[0016] Asphalt modifier, its preparation method is as follows:

[0017] Put the bitumen in the parts by weight into the reaction kettle for heating, add sodium dodecylbenzenesulfonate, furan resin and water after 20 minutes, stir while adding, until evenly stirred.

Embodiment 2

[0019] The asphalt modifier is composed of the following components in the following parts by weight:

[0020] Bituminous mixture: sodium dodecylbenzenesulfonate: furan resin: water: = 80:5:0.1:40.

[0021] Its preparation method is with embodiment 1.

Embodiment 3

[0023] The asphalt modifier is composed of the following components in the following parts by weight ratio:

[0024] Bituminous mixture: sodium dodecylbenzenesulfonate: furan resin: water: =70:10:1:50.

[0025] Its preparation method is with embodiment 1.

Abstract

The invention relates to an asphalt modifier comprising the following components in parts by weight: 30-80 parts of asphalt mixtures, 5-20 parts of sodium dodecyl benzene sulfonate, 0.1-5 parts of furan resins and 40-80 parts of water. The invention has the advantages that the sodium dodecyl benzene sulfonate, the furan resin and the water are added in the producing process of the asphalt mixtures, and then a lubricating macromolecular chain structure is formed in a cementing material, thereby greatly reducing the mixing and grinding temperature of the asphalt mixtures and saving the energy consumption; in addition, the invention has the advantages of good compaction performance, reduced grinding times, good pavement quality, better high-temperature anti-rutting capacity, water damage resistant capacity, ageing resistant capacity, and the like, small discharge amount of smoke and gases, great environmental protection and wide application scope and can be used for paving tunnel pavements, steel bridge surfaces, heavy-load roads or airfield runways, and the like.

Description

technical field [0001] The invention relates to an asphalt modifier and belongs to the field of chemical industry. Background technique [0002] In modern society, due to the sharp increase in traffic flow and driving frequency, the axle load of freight vehicles continues to increase, and one-way driving in separate lanes is generally implemented. The ability to resist cracking at low temperature; improve wear resistance and prolong service life. The existing petroleum asphalt is no longer suitable for changes in the road surface environment, so people have developed modified road asphalt. This modified asphalt has better performance, but the price is relatively high, and it is not suitable for large-scale popularization and application. Contents of the invention [0003] The technical problem to be solved by the invention is to provide an asphalt modifier with low raw material cost, good road surface quality and wide application range. [0004] In order to solve the pro...
