Embodiment 1

[0025] Example 1 Preparation of SMA-13 ​​warm mix foamed asphalt mixture

[0026] 1. Material preparation:

[0027] The asphalt is modified asphalt, and the SBS modified asphalt produced by Jiangsu Baoli Asphalt Co., Ltd. is used in this embodiment.

[0028] 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. 9.5 ~ 16mm, the ratio of each file is: 2...

Embodiment 2

[0037] Example 2 Preparation of AC-13 warm mix foamed asphalt mixture

[0038] 1. Material preparation:

[0039] The asphalt is modified asphalt, and the SBS modified asphalt produced by Jiangsu Baoli Asphalt Co., Ltd. is used in this embodiment.

[0040] For crushed stone aggregates, the crushed stone aggregates are graded according to the commonly used classification requirements. The grades used in this embodiment are: 0-2.36mm, 2.36-4.75mm, 4.75-9.5mm and 9.5-16mm. The ratio is: 28.30% : 15.20% : 30.40% : 26.10%, and they are added at the same time.

[0041] Limestone slag, mainly composed of calcium carbonate, requires limestone slag processed from limestone.

[0042] Bitumen 5.3%

[0043] Crushed stone aggregate 88.7%

[0044] Limestone Mineral Powder 6%

[0045] 2. Prepare the energy-saving and emission-reducing asphalt mixture with the above materials according to the following steps:

[0046] Step 1: add crushed stone aggregates to limestone powder in proportion...

Embodiment 3

[0049] Example 3 Preparation of SUP-13 warm mix foamed asphalt mixture

[0050] 1. Material preparation:

[0051] The asphalt is modified asphalt, and the SBS modified asphalt produced by Nantong Tongsha Asphalt Technology Co., Ltd. is used in this embodiment.

[0052] For crushed stone aggregates, the crushed stone aggregates are graded according to the commonly used classification requirements. The grades used in this embodiment are: 0-2.36mm, 2.36-4.75mm, 4.75-9.5mm and 9.5-16mm. The ratio is: 31.10% : 16.50% : 41.60% : 10.80%, and they are added at the same time.

[0053] Limestone slag, mainly composed of calcium carbonate, requires limestone slag processed from limestone.

[0054] Bitumen 5.5%

[0055] Crushed stone aggregate 88.5%

[0056] Limestone Mineral Powder 6%

[0057] 2. Prepare the energy-saving and emission-reducing asphalt mixture with the above materials according to the following steps:

Abstract

The invention relates to an energy-saving emission-reducing type asphalt mixture and a preparation method thereof and belongs to the technical field of engineering. By adopting the energy-saving emission-reducing type asphalt mixture, the demands of the asphalt mixture on environment temperature can be reduced, the annual construction time can be prolonged, better compaction function can be provided, the service life of a pavement is prolonged and effective guarantee for safe driving is provided; by adopting the energy-saving emission-reducing type asphalt mixture, a lot of fuel oil can be saved, and the discharge of greenhouse gas is reduced, so that the environment protection cost can be reduced and economical effect is more obvious; in addition, by applying the energy-saving emission-reducing type asphalt mixture, good social effect for establishing Chinese resources-saving society is provided, the discharge of carbon dioxide can be reduced, poisonous gases such as carbon monoxide, sulfur trioxide and nitric oxide also can be greatly reduced, and extremely important practical significances for saving social sources and protecting environment are provided.

Description

technical field [0001] The invention relates to an energy-saving and emission-reducing asphalt mixture and a preparation method thereof, in particular to a warm-mix foaming asphalt mixture and a preparation method 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. [0003] It is estimated that in 2004 the carbon dioxide emission of my country's transportation industry was about 290 mi...
