Road repair and maintenance asphalt cold patch material is an efficient and convenient road repair material. The following is a detailed introduction:
1. Definition and composition
Asphalt cold patching material, also known as cold patching material, cold patching asphalt mixture or cold mix asphalt material, is a patching material composed of matrix asphalt, isolation agent, special additives and aggregates (such as gravel). These materials are mixed according to a certain proportion in professional asphalt mixing equipment to make "asphalt cold replenishing fluid", and then mixed with aggregates to finally make finished materials.
2. Features and advantages
Modified, not completely thermoplastic: Asphalt cold patch material is a modified asphalt mixture, which has the significant advantages of direct injection and high performance.
Good stability: At normal temperature, asphalt cold patch material is liquid and thick, with stable properties. It is the core raw material for cold patch production.
Wide range of application: It can be used between -30℃ and 50℃, and can be used all-weather. It is suitable for repairing various types of road surfaces in any weather and environment, such as asphalt, cement concrete roads, parking lots, airport runways, and bridges. Scenarios such as expansion joints, potholes on highways, national and provincial highways and municipal highways, community excavation and filling, pipeline backfilling, etc.
No heating required: Compared with hot mix, asphalt cold patch material can be used without heating, reducing energy consumption and emissions.
Easy to operate: When using, just pour the cold patching material into the pits and compact it with a shovel or compaction tool.
Excellent performance: Asphalt cold patch material has high adhesion and cohesion, can form an overall structure, and is not easy to peel and move.
Convenient storage: Unused asphalt cold patch material can be stored sealed for subsequent use.

Asphalt mixing equipment is equipment used to produce asphalt concrete in large quantities. Because this equipment is affected by various factors during the production process, some problems will inevitably occur after a period of use. Sinoroader Group Asphalt Mixing Equipment An editor from an equipment company would like to introduce to you how to save damaged parts in asphalt mixing equipment.

Asphalt mixing station is constructed according to certain steps, which can not only ensure the construction quality, but also ensure that the asphalt mixer is not damaged. Although the construction details are very important, the key methods of asphalt mixing station construction should also be used flexibly. Let's take a look at the mesh belt of Sinoroader Group asphalt mixing station;

Methods and steps:
1. Pavement preparation: Before construction begins, the pavement needs to be prepared. This includes cleaning debris and dust on the pavement and ensuring that the pavement is flat.
2. Base treatment: Before pavement construction, the base needs to be treated. This may include filling potholes and repairing cracks, and ensuring the stability and flatness of the base.

1. The paving temperature of asphalt pavement is generally 135~175℃. Before paving the pavement asphalt, it is necessary to remove the debris on the pavement base to ensure that the pavement base is dry and clean. At the same time, it is necessary to ensure the rationality of the density and thickness of the base pavement, which lays an important premise for asphalt paving.

Cleaning the asphalt tank of a large asphalt spreader is an important part of ensuring construction quality and equipment life. Cleaning work needs to be meticulous and thorough. The following describes how to clean it from several aspects:
