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
The present invention relates to a kind of asphalt modifier, belong to chemical field.
Background technology
Modern society is owing to the traffic flow and the frequency sharp increase of travelling, and the divided lane one-way traffic is generally carried out in the heavy constantly increase of the axle of freight, requires further to improve road surface resistance to flow, the i.e. ability of anti-rut under the high temperature; Improve flexibility and elasticity, the i.e. ability of cracking resistance under the low temperature; Improve the abrasion performance ability and increase the service life.Existing petroleum pitch is the variation of incompatibility road environment, so people develop modified pavement asphalt, and this performance of modified bitumen is better, but price is higher, is not suitable for applying on a large scale.
Summary of the invention
The technical problem to be solved in the present invention provides that a kind of raw materials cost is low, pavement quality good, the asphalt modifier of applied range.
In order to solve the problem that prior art exists, the technical solution used in the present invention is:
Asphalt modifier, form according to the following number of weight ratio by following component:
Asphalt mixture: Sodium dodecylbenzene sulfonate: furane resin: water :=30-80: 5-20: 0.1-5: 40-80.
Described asphalt modifier, form according to the following number of weight ratio by following component:
Asphalt mixture: Sodium dodecylbenzene sulfonate: furane resin: water :=40-70: 10-15: 1-3: 50-70.
Described asphalt modifier, form according to the following number of weight ratio by following component:
Asphalt mixture: Sodium dodecylbenzene sulfonate: furane resin: water :=55: 12: 2: 60.
Advantage and effect that the present invention had are:
Asphalt modifier of the present invention adds Sodium dodecylbenzene sulfonate, furane resin and water in the asphalt production process, add the back and lubricate polymer chain structure inner formation of agglutinate, reduce mixing and stirring of compound greatly and close temperature, save energy consumption with stone roller; Compaction capacity is good, reduces and rolls number of times; Pavement quality is good, has high temperature rutting resistance, anti-water damage ability and resistance of aging etc. preferably; Smog and gas emissions are few, very environmental protection.Applied range, can use at tunnel road surface, steel bridge face pave, heavily loaded road or airfield runway etc.
