Embodiment 1

[0022] (1) After mixing the waste PE plastic and sodium chloride evenly according to the mass ratio of 55:45, under the temperature condition of 190 ℃, extrude and process it into 5-20 mesh plastic slow-release granules through special equipment;

[0023] (2) Plastic slow-release granules and 5-20 mesh waste tire rubber granules are uniformly mixed according to the mass ratio of 1:1, and the obtained mixture is the self-melting asphalt mixture additive;

[0024] (3) The self-melting ice asphalt mixture additive 4% equivalent replacement powder filler when asphalt concrete mixture is produced, and adopts commonly used asphalt mixture production technology to produce self-melting ice asphalt mixture, test shows, in Under the action of the 200kpa pressure of the running wheels, the released sodium chloride particles keep the road surface from freezing at -11°C.

Embodiment 2

[0026] (1) After mixing the waste PC plastic and sodium chloride evenly according to the mass ratio of 45:55, under the temperature condition of 290 ℃, extrude and process it into 10-30 mesh plastic slow-release granules through special equipment;

[0027] (2) The plastic slow-release granules and the 10-30 mesh waste tire rubber granules are uniformly mixed according to the mass ratio of 2:1, and the obtained mixture is the self-melting asphalt mixture additive;

[0028] (3) The self-melting ice asphalt mixture additive 6% equivalent of making will replace the powder filler when asphalt concrete mixture is produced, and adopt the commonly used asphalt mixture production technology to produce self-melting ice asphalt mixture, the test shows that, in Under the action of 200kpa pressure and 350kpa pressure of running wheels, the released sodium chloride particles can keep the road surface from freezing at -25°C.

Embodiment 3

[0030] (1) After mixing the waste PP plastic and sodium chloride evenly according to the mass ratio of 40:60, under the temperature condition of 260°C, extrude and process it into 10-20 mesh plastic slow-release granules through special equipment;

[0031] (2) The plastic slow-release granules and the 10-20 mesh waste tire rubber granules are uniformly mixed according to the mass ratio of 3:1, and the obtained mixture is the self-melting asphalt mixture additive;

[0032] (3) The self-melting ice asphalt mixture additive 5% equivalence of making replaces the powder filler when the asphalt concrete mixture is produced, and adopts the commonly used asphalt mixture production technology to produce the self-melting ice asphalt mixture. The test shows that in Under the action of 300kpa pressure of running wheels, the released sodium chloride particles can keep the road surface from freezing at -26°C.

Abstract

The invention discloses a self-ice-melting asphalt mixture additive and a preparation process. Waste plastic and chloride salt or acetate salt are dissolved in a range of 160 DEG C to 350 DEG C afterbeing evenly mixed according to a certain mass ratio, and are extruded or extruded, then the mixture is processed into 5 to 40-mesh plastic sustained-release pellets through an extrusion molding device or an injection molding device; the plastic sustained-release pellets with the same particle size are uniformly mixed with rubber pellets according to a certain mass ratio to obtain the self-ice-melting asphalt mixture additive; when road pavement asphalt is produced, the self-ice-melting asphalt mixture additive replaces a powder filler by equal amounts, and an asphalt road surface added with the self-ice-melting asphalt mixture slowly release to melt ice under action of wheel pressure of automobiles. The ice melting effect is good and the service life is long.

Description

technical field [0001] The invention relates to a self-melting ice asphalt mixture additive and a preparation process. Background technique [0002] The skid resistance of the road surface is a key factor to ensure the safe driving of vehicles. At present, asphalt pavement is paved and rolled by asphalt mixture composed of asphalt, sand and gravel, stone powder cement and other fillers in a certain proportion. In winter, asphalt pavement is icy. brought many hidden dangers. Therefore urgently need a kind of self-thawing asphalt mixture additive and preparation technology, in order to guarantee the safe running of vehicle in winter. Contents of the invention [0003] Based on the above deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a self-melting ice-melting asphalt mixture additive with good ice-melting effect and its preparation process. The self-melting ice-melting asphalt mixture additive can achieve slow relea...
