Abstract
The invention discloses a preparing method of a phosphorus slag powder and polyester fiber composite modified asphalt mixture. Phosphorus slag micro powder is screened till particles with the diameter larger than 0.075 mm is smaller than 2% and doped into asphalt, and phosphorus slag micro powder asphalt is obtained through shearing of high-speed shearing dispersing emulgators; polyester fibers are manually dispersed; the shorn and dispersed polyester fibers are added into a phosphorus slag micro powder asphalt mixture, even stirring is performed at the temperature of 155 DEG C, and the phosphorus slag powder and polyester fiber composite modified asphalt mixture is obtained. Compared with the prior art, the modified asphalt mixture prepared from the phosphorus slag micro powder produced by industrial waste residues, namely the phosphorus slag and the polyester fibers in a combined admixture mode has the advantages that raw materials are low in price and easy to obtain, the preparing process is simple, machining and forming are convenient, the modified asphalt mixture is environmentally friendly and free of poison and excellent in pavement performance, and the prepared phosphorus slag powder and polyester fiber composite modified asphalt mixture is good in high-and-low temperature property and water damage resistance and can be widely applied to road surfaces of highways and high-grade highways.
Description
Technical field
The present invention relates to Road construction field of bitumen technology, particularly the preparation method of a kind of phosphorus slag powder and trevira composite modified asphalt mixture.
Background technology
Along with the continuous improvement of traffic construction, more and more higher to the performance requriements of bituminous material, especially there is new requirement especially in the location (bridge floor, airport, runway, heavy-load road) of some condition harshnesses.
At present, the pitch in the harsh location of the condition that is used in is SBS modifying asphalt mostly.SBS modifying asphalt is more satisfactory as motorway road-making material, but the high and low temperature resistance of SBS modifying asphalt and anti-water damage property come with some shortcomings, and complex manufacturing, and cost of manufacture is high.
Summary of the invention
The object of the invention is to solve the deficiencies in the prior art and provide a kind of preparation process simple, machine-shaping is convenient, the preparation method of the phosphorus slag powder that environmental friendliness is nontoxic and trevira composite modified asphalt mixture.
For achieving the above object, the present invention implements according to following technical scheme:
A preparation method for phosphorus slag powder and trevira composite modified asphalt mixture, comprises the following steps:
1) getting the phosphorous slag micropowder accounting for asphalt quality 8% ~ 12% is incorporated in pitch, shears obtain phosphorous slag micropowder pitch through high speed shear dispersion emulsifier;
2) scattered trevira is joined in phosphorous slag micropowder asphalt by 0.1% ~ 0.2% of phosphorous slag micropowder quality of asphalt mixtures, stir under temperature is 155 DEG C of conditions, obtain phosphorus slag powder and trevira composite modified asphalt mixture.
As the further preferred version of the present invention, the granule content being greater than 0.075mm in described phosphorous slag micropowder is less than 2%.
As the further preferred version of the present invention, described phosphorous slag micropowder accounts for 10% of asphalt quality;
As the further preferred version of the present invention, described trevira accounts for the quality 0.15% of phosphorous slag micropowder asphalt.
Compared with prior art, the modified asphalt mixture that the present invention utilizes the phosphorous slag micropowder of industrial residue-phosphorus ore slag production and trevira to mix preparation again has cheaper starting materials and is easy to get, preparation process is simple, machine-shaping is convenient, environmental friendliness is nontoxic, the advantage of pavement performance excellence, the phosphorus slag powder prepared and trevira composite modified asphalt mixture have good high temperature performance and anti-water damage property, can apply in the road surface of motorway and high-grade highway and road surface nursing widely, to improving the quality of China's motorway and high-grade highway and all having great significance to the fast development of China's economy.
