Embodiment 1

[0031] 1. Material preparation:

[0032] Water, use potable tap water.

[0033] Asphalt is 70# road petroleum asphalt, which is the asphalt produced by Taizhou Plant of CNOOC in this embodiment.

[0034] Crushed stone aggregate, also known as aggregate. One of the main components of asphalt concrete, it mainly acts as a skeleton and reduces the volume change caused by the shrinkage and swelling of the cementitious material during the setting and hardening process, and is also used as a cheap filler for the cementitious material. There are natural aggregates and artificial aggregates, the former such as gravel, pebbles, pumice, natural sand, etc.; the latter such as cinder, slag, ceramsite, expanded perlite, etc. The stone material used in this example is sieved crushed stone, and the crushed stone aggregate is classified according to the commonly used classification requirements. 13.2 to 26.5mm, and the sum of crushed stone aggregates should be less than 100, which is betwe...

Embodiment 2

[0042] 1. Material preparation:

[0043] Water, use potable tap water.

[0044] Asphalt, Shell 70# road petroleum asphalt is used.

[0045] Crushed stone aggregate, also known as aggregate. One of the main components of asphalt concrete, it mainly acts as a skeleton and reduces the volume change caused by the shrinkage and swelling of the cementitious material during the setting and hardening process, and is also used as a cheap filler for the cementitious material. There are natural aggregates and artificial aggregates, the former such as gravel, pebbles, pumice, natural sand, etc.; the latter such as cinder, slag, ceramsite, expanded perlite, etc. The stone material used in this example is sieved crushed stone, and the crushed stone aggregate is classified according to the commonly used classification requirements. 13.2~26.5mm, the proportions of each file are: 26.64%: 11.00%: 24.00%: 31.00%, and they are added at the same time.

[0046] Limestone slag, mainly composed o...

Embodiment 3

[0053] 1. Material preparation:

[0054] Water, use potable tap water.

[0055] Asphalt, adopt 70# road petroleum asphalt, what this embodiment adopts is the asphalt produced by Jiangsu Baoli.

[0056] Crushed stone aggregate, also known as aggregate. One of the main components of asphalt concrete, it mainly acts as a skeleton and reduces the volume change caused by the shrinkage and swelling of the cementitious material during the setting and hardening process, and is also used as a cheap filler for the cementitious material. There are natural aggregates and artificial aggregates, the former such as gravel, pebbles, pumice, natural sand, etc.; the latter such as cinder, slag, ceramsite, expanded perlite, etc. The stone material used in this example is sieved crushed stone, and the crushed stone aggregate is classified according to the commonly used classification requirements. 13.2~26.5mm, the proportions of each file are: 28.85%: 10.00%: 24.00%: 31.00%, and they are added...

Abstract

The invention relates to a warm mix asphalt mixture as well as a preparation method and equipment thereof, in particular to a micro-foamed warm mix asphalt mixture as well as a preparation method and equipment thereof, and belongs to the technical field of engineering. An asphalt micro-foaming formula and the equipment are matched for use. During mixture production, by the aid of the equipment, asphalt is fully foamed, a binder is sprayed into a mixing cylinder in the form of foamed asphalt and mixed with aggregate to form the warm mix asphalt mixture, the foamed asphalt is lower than the asphalt in viscosity and higher in workability and can fully cover the aggregate at the lower temperature, the mixing temperature of the warm mix asphalt mixture is reduced, and the micro-foamed warm mix asphalt mixture is produced. The micro-foamed warm mix asphalt mixture as well as the preparation method and the equipment thereof have benefits as follows: warm mixing of the warm mix asphalt mixture is realized by the aid of micro-foaming equipment, the cost for purchasing the equipment is only input once, and a small amount of water is sprayed in production. The production cost of the warm mix asphalt mixture is reduced, the once-and-for-all effect can be realized, and the method is more energy-saving and environment-friendly when compared with a traditional technology that warm mix materials are added for warm mixing.

Description

technical field [0001] The invention relates to a warm-mix asphalt mixture and a preparation method and equipment thereof, in particular to a micro-foaming warm-mix asphalt mixture and a preparation method and equipment thereof, belonging to the technical field of engineering. Background technique [0002] The global energy shortage and climate change have become a major concern of the international community, and energy conservation and emission reduction have become the common responsibility of the international community. As the largest developing country in the world, my country is increasingly becoming the object of global attention. The transportation industry is a large energy consumer in my country, an important field for building a resource-saving and environment-friendly society, and an important source of greenhouse gas and air pollution emissions. It is estimated that in 2004 the carbon dioxide emission of my country's transportation industry was about 290 milli...
