Modified asphalt

Abstract

Modified asphalt is provided. The modified asphalt includes matrix asphalt and a modifier. The modifier includes palm fruit shell ash and waste engine oil. The palm fruit shell ash is ash generated after palm fruit shell is combusted. The waste engine oil is engine oil wasted after vehicle maintenance. A large amount of palm fruit shell is adopted, thus providing a beneficial supplement for the flourishing palm oil industry at present, reducing pollution caused by secondary treatment of the palm fruit shell ash and the waste engine oil, reducing the fuel using amount during modified asphalt production, and meeting the social requirements of energy conservation and emission reduction at present. A construction process is convenient, the cost is low, and the effective utilization rate is increased. The modified asphalt can be widely used in highway and building projects, and has significant economic benefit and social benefit.

Description

technical field [0001] The invention belongs to the technical field of road materials, and in particular relates to a modified asphalt. Background technique [0002] With the improvement of people's living standards in our country, the quality requirements for edible oil are increasing year by year, and the consumption of palm oil will not increase the cholesterol in the serum, but has a tendency to reduce cholesterol, which is accepted by more and more people. China is the world's largest consumer of edible oil, with a total annual consumption of more than 25 million tons of edible oil. The proportion of palm oil is increasing year by year, and related palm oil companies are also showing an increasing trend year by year. The palm fruit grown in Guangdong, Guangxi, Yunnan and other provinces in the south cannot meet my country's annual palm oil consumption, and a large amount must be imported from Malaysia and Indonesia. In the process of producing palm oil, a large amount ...

AI Technical Summary

Problems solved by technology

In the process of producing palm oil, a large amount of palm shells are also produced. At present, the most commonly used method is to use palm shells as fuel. This method is commonly used in some cement factories in Malaysia, but it is only used in the above-mentioned areas in China. Handle palm shells, because in the current situation of serious air pollution, it will increase the emission of greenhouse gases, and palm shell ash will also increase the generation of smog, which will aggravate air pollution

[0003] With the continuous improvement of the current highway network, my country's highway construction has entered a period of good and stable development. As more and more highways gradually enter the maintenance period, the problem of damage to asphalt concrete pavement is becoming more and more common. The commonly used methods are Milling off and then resurfacing, but this method has a long construction period and requires partial closure of traffic. In order to improve the road performance of asphalt concrete, most of the asphalt binders used are imported SBS modified asphalt, modified by adding SBS agent in asphalt to improve or enhance the performance of asphalt, and then improve the performance of modified asphalt concrete

Although it plays a certain role in improving the use effect of asphalt pavement, there is no breakthrough progress. It is just a usage method that has been established in the industry since the development of expressways. Although some experience has been accumulated after decades of use, there are still many shortcomings. For example, the function is single; without saving energy, the asphalt and mineral materials still need to be heated to 180-220°C when modifying, which will consume a lot of energy; Rapid prototyping of paving and rolling; did not effectively reduce the cost of road construction, and closed the traffic, affecting the smooth passage of vehicles, but increased the cost of road laying to a certain extent; did not achieve the purpose of greatly reducing pollution and carbon emissions
