Problems solved by technology

However, due to the poor permeability of emulsified asphalt, it can reach up to about 4mm, which affects the quality of asphalt pavement.
Diluted asphalt is used as the penetrating layer oil, because it needs to add a weight ratio of asphalt: thinner at least 1:1, and currently gasoline, kerosene, diesel oil, etc. are mainly used as diluents to add to petroleum asphalt, which is characterized by permeability Well, it can penetrate the semi-rigid base layer to a depth of more than 5-10mm. However, due to the high price of raw materials such as gasoline, kerosene, and diesel oil used as diluents, the cost of dilute asphalt used as penetrating oil is very high, and it is not popular in my country.

Embodiment 1

[0009] First weigh 50kg of asphalt used for road construction, then add 3kg of diluent, mix evenly by mechanical stirring, then add 45kg of water, 1kg of emulsifier, 0.5kg of stabilizer and 0.5kg of modifier, in the asphalt emulsification equipment After emulsification, it is the finished product.

[0010] The above-mentioned gasoline or kerosene or diesel oil as diluent can be compounded in any proportion as required, such as: gasoline: kerosene: diesel oil is 1:1:1, all 1kg. It is also possible to add only any one of the above three types according to the conditions of the construction area.

Embodiment 2

[0012] Weigh 30kg of asphalt for road construction, then add 15kg of diluent, mix evenly by mechanical stirring, add 50kg of water, 2kg of emulsifier, 1kg of stabilizer and 2kg of modifier, and emulsify in asphalt emulsification equipment, That is the finished product. The diluent can be compounded by gasoline: kerosene: diesel oil at a ratio of 1:2:3, or it can be compounded in other proportions according to the actual situation.

Embodiment 3

[0014] Weigh 40kg of asphalt for road construction, then add 10kg of diluent, mix evenly by mechanical stirring, add 43kg of water, 2kg of emulsifier, 2.5kg of stabilizer and 2.5kg of modifier, and emulsify in the asphalt emulsification equipment After that, it is the finished product. The diluent is made of gasoline: kerosene: diesel at a ratio of 1:5:1, and can also be compounded in other proportions according to actual conditions.

[0015] In the above embodiments, low-grade gasoline is used for gasoline, and kerosene and diesel oil can use corresponding grades with good fluidity according to the construction season, such as diesel oil with a grade of -10 or lower in winter, and diesel oil with a grade above 0 in summer. The selection criteria of diluent mainly consider the temperature during construction and the condition of penetration depth of 5-10mm or more, so as to reduce the cost as much as possible.

[0016] As the emulsifier in the above examples, the asphalt emul...

Abstract

The invention relates to an intensive infiltration emulsified asphalt and its preparation, wherein the emulsified asphalt comprises (by weight percent) asphalt 30-50%, water 45-50%, emulsifying agent 0.8-2%, thinning agent 2-15%, balancing stabilizing agent and modifying agent.

Description

technical field [0001] The invention relates to a penetrating layer asphalt for road repair and a preparation method thereof, in particular to a strong penetrating emulsified asphalt and its preparation. Background technique [0002] During the construction of asphalt pavement, all kinds of bases must be sprayed with permeable asphalt (commonly known as permeable oil). The asphalt layer must be paved after the permeable asphalt has completely penetrated into the base. -10mm or more, if the asphalt in the permeable layer cannot penetrate into the base layer and is only sprinkled on the surface to form an oil film, the asphalt in the permeable layer will not be able to play the role of consolidation, stability, connection, waterproofing, etc., thus affecting the service life of the asphalt pavement. [0003] At present, what to use as the penetrating layer oil has always been a perplexing problem in road construction projects. The American Asphalt Association MS-22's descript...
