Embodiment Construction

[0028] An asphalt material for roads, the composition of which consists of 1-20% of natural rock asphalt, and the rest is matrix asphalt. Its base asphalt is 70# base asphalt or 90# base asphalt.

[0029] The preparation method of above-mentioned asphalt material for road, comprises the steps:

[0030] (1) Weigh the matrix asphalt and natural rock asphalt according to their weight percentage, and set aside;

[0031] (2) Put the base asphalt of the above weight into the heating tank, and then heat up the required equipment, the temperature of the heating tank storing the base asphalt is raised to 165°C, and the temperature of the asphalt conveying pipeline, mixing tank, metering tank, and ball mill is raised to 165°C , and then drive the base asphalt in the heating tank into the mixing tank through a delivery pump, and keep the temperature of the mixing tank between 160 and 165°C; 164°C, 163°C, 162°C, and 161°C are all available Preferably 165°C;

[0032] (3) Add the natural...

Abstract

The invention relates to an asphalt material for a road as well as a preparation method and a preparation device of the asphalt material. The asphalt material comprises the following ingredients through being metered by weight percentage: 1 to 20 percent of natural rock asphalt and the rest of substrate asphalt. The preparation method of the asphalt material comprises the following steps that two kinds of asphalt are weighed according to the weight percentage; the substrate asphalt is filled in a temperature rise tank, and the temperature is raised to 165 DEG C; the substrate asphalt in the temperature rise tank is pumped into a 160-165-DEG C stirring tank by a conveying pump; the natural rock asphalt is added into the stirring tank to be mixed and stirred for 10 minutes; mixed materials are pumped into a metering tank, after the weight of the mixed materials is metered, the mixed materials are added into a ball grinder, the temperature of the ball grinder reaches 165 DEG C, in addition, the temperature is maintained at 165 DEG C, a grinding device of the ball grinder is opened, and the rotating speed of the grinding device is gradually regulated to 400 to 500 turns / minute; and the grinding is carried out for 10 to 30 minutes, and the materials are discharged. The bonding capability of the prepared asphalt and stone is high, the elasticity is good, the stretching quantity is great, the asphalt material is not soluble in water, no water seeps, the flowing during high temperature and the brittle fracture during low temperature are avoided, the durability is good, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of road materials, in particular to a modified asphalt material with excellent high-temperature and low-temperature performance and water damage resistance, a preparation method and a preparation device thereof. Background technique [0002] With the rapid development of my country's transportation industry, the quality requirements for road construction are also increasing. At present, my country's road construction materials include: SBS modified asphalt, emulsified asphalt, rock asphalt modified asphalt, etc. However, the high-temperature performance is not good, and the water damage resistance is poor, causing various diseases, such as rutting, network cracking, etc. Modified asphalt with this performance can no longer meet people's requirements for high-quality roads and bridges. Therefore, the development of asphalt materials for roads with good high and low temperature performance and water damage re...
