Embodiment 1

[0019] The ratio of each raw material in the main material and auxiliary material, and the compounding ratio of the main material and auxiliary material can be determined through experiments according to the needs of customers.

[0020] As a further illustration, the ratio of each raw material in the main material and the auxiliary material, the compounding ratio of the main material and the auxiliary material are determined according to the customer's needs through experiments, and then the main material and the auxiliary material are evenly mixed, and then the product can be obtained by sub-packaging.

[0021] The main material is 800g of diatomite, 400g of clay ore, 400g of bentonite, a total of 1600g; the auxiliary materials are 200g of coal tar pitch, 200g of natural asphalt, a total of 400g, and a total of 2000g of main materials + auxiliary materials. Type asphalt modifier 2000g.

[0022] Take 8.8kg of No. 90 A-grade heavy-duty petroleum asphalt, heat it to 160°C, add 1...

Embodiment 2

[0027] The main material is 700g of diatomite, 400g of clay ore, 400g of bentonite, 1500g in total; the auxiliary materials are 300g of petroleum asphalt, 100g of rubber powder, 100g of mica powder, 500g in total, and the total of main material + auxiliary material is 2000g. After fully mixing, it is made A composite asphalt modifier 2000g.

[0028] Take 8.8kg of No. 90 A-grade heavy-duty petroleum asphalt, heat it to 160°C, add 1.2kg of the mixed asphalt modifier prepared above, and stir for 50 minutes to obtain 10kg of modified asphalt, and make AC according to the asphalt ratio of 5.5%. -13C composite modified asphalt mixture, the measured technical performance indicators are shown in Table 2.

Abstract

The invention discloses a composite asphalt modifier. The composite asphalt modifier comprises main materials and assistants, the percentage of the main materials account foris 75-80 percent, and the percentage of the assistants is 20-25 percent. A preparation method of the composite asphalt modifier is as follows: according to the demand of a customer, the proportions of the compositions in the main materials and the assistants and the proportions of the main materials and the assistants are determined via tests, and then the mixed main materials and the assistants are independently packed so as to obtain the finished product. The composite asphalt modifier provided by the invention is low in production investment, simple in modification process and better in stability after modification, and has a very good popularization value.

Description

technical field [0001] The invention relates to an asphalt modified material, in particular to a composite asphalt modifier. Background technique [0002] Asphalt has waterproof and anti-corrosion properties, and is widely used in pavement paving materials and covering materials, etc. However, asphalt pavement often cracks, which directly affects the service life of asphalt pavement. [0003] With the rapid development of my country's highway traffic, by the end of 2012, the total mileage of national highways reached 4.2375 million kilometers. Among them, the national highway mileage reached 96,200 kilometers, the mileage of secondary and above roads was 501,900 kilometers, 96.9% of the townships (towns) connected to asphalt roads, and 67.1% of the official villages connected to asphalt roads. Taking expressways and first-class highways as an example, in the "Code for Design of Highway Asphalt Pavement" (JTD G50-2006), the design period is 15 years, but most expressways and...
