During application, when the temperature of the asphalt mixture reaches 110 to 130 DEG C, 5 percent of the diluent of the additive is added by the mass of asphalt in a spraying mode so as to realize the warm mixing technology of mixing and spreading the asphalt mixture; and test data show that various road indexes of the warm-mixed asphalt mixture are not lower than that of hot-mixed asphalt mixture under the condition that the mixing and molding temperature of the warm-mixed asphalt mixture is obviously reduced relative to the hot-mixed asphalt mixture.
Description
Technical field
The present invention relates to a kind of asphalt additive and preparation method thereof, specifically, relate to that a kind of construction work uses, and can make production and construction temperature warm-mixed asphalt additive between hot-mix asphalt mixture and cold-mix asphalt compound and preparation method thereof.
Background technology
At present, the asphalt highway construction has two kinds usually with asphalt preparation technology: heat is mixed and stirred cold mixing.
Hot-mix asphalt mixture is built the road technology through the development of decades, and its application level is ripe day by day, and its effect is also obvious to all.But, along with the development of society and the raising of people's level of understanding, hot-mix asphalt mixture the system of mixing, transport and the process that paves in problem such as the thermal ageing, high energy consumption and the noxious gas emission that occur be too much, the technician by various countries is paid close attention to gradually.One, the system of mixing and the construction temperature of hot-mix asphalt mixture are quite high, usually up to 150 ℃～190 ℃, in so high temperature and have under the situation that oxygen exists, it is inevitable that bituminous wears out.Simultaneously, when mixing and stirring pitch wrap up in be attached to the asphalt membrane on gathering materials thickness basically all below 10 μ m, aggravated bituminous thermal ageing degree especially greatly, so that make the pavement performance of asphalt be subjected to very big influence.Its two, nowadays, not only energy-saving and cost-reducing is economic problems, energy dilemma has also become the bottleneck of restriction China Sustainable development.Pitch and gathering materials is heated to the temperature up to more than 150 ℃ respectively, must consume a large amount of energy, runs counter to energy-saving and cost-reducing aim.They are three years old, hot-mix asphalt mixture mix and stir the temperature height, mix system until paving process from compound, the capital discharges a large amount of obnoxious flavoures, objectionable constituent in these obnoxious flavoures mainly are CO, CO2, SO2 and NOx class etc., not only pollute atmospheric environment, also damaging the healthy of workmen.
Cold mixing raw material that technology is used be emulsified bitumen, and, cause pitch to have molecular rupture, the situation of degradation because emulsified bitumen has adopted the preparation technology of high temperature, high speed shear in preparation process.Although during construction, cold-mix asphalt has certain advantage at aspects such as anti-aging, less energy-consumption, environmental protection, but the hot-mix asphalt mixture gap that its pavement performance compares is bigger, therefore can only be used for the following surface layer and the basic unit on the repairing of bituminous pavement, low volume of traffic road surface, heavy traffic flow road surface.
Therefore, hot asphalt and cold-mix asphalt all exist drawback to a certain extent, or influence the bituminous performance, or are unfavorable for saving energy and reduce the cost, and also pollute the environment.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of production and construction temperature warm-mixed asphalt additive between hot-mix asphalt mixture and cold-mix asphalt compound and preparation method thereof that makes, during application, when the asphalt temperature reaches 110～130 ℃, add the diluent of additive of the present invention according to 5% mass parts of pitch amount with spray pattern, can realize that asphalt mixes and stirs and the temperature that paves is mixed technology.
