Basics
Asphalt concrete is a concrete plate formed by mixing various specifications of aggregate (sand, stone), binder (asphalt or residue) and filler (mineral powder) in a certain proportion to form an asphalt mixture. The mechanical equipment used for mixing asphalt mixture is called asphalt concrete mixing equipment – bitumen hot mix plant. It is the necessary equipment for building expressways, grade highways, municipal roads, airports and ports. There are various types of asphalt mixing plant, click here to learn more information.
The cold mix asphalt plant describes the asphalt mixture blended by unheated aggregate, mineral filler and also asphalt watered down. The cold asphalt mixture is a modern roadway maintenance service material, which can be utilized all day. It appropriates for repairing various road pavement surface areas under any environment, such as asphalt concrete roadway, car park, airport runway and also bridges growth joint.
Bitumen Hot Mix Plant VS Cold Mix Plant
Bitumen Hot Mix Plant
| The heating and drying of aggregate is an indispensable process. |
| The laying of manufactured asphalt finished material needs to follow the temperature requirement, and it can only work in certain temperature. |
| Due to heating and drying of aggregate, the bitumen hot mix plant will produce some dust and black smoke in the process of manufacturing asphalt mixture, which causes some pollution to the environment through it’s equipped with the dust collector. |
| There are certain safety hazards in controlling and operating the hot mix asphalt plant because the increase of burner flame may cause aggregate combustion, which may injures workers. |
| The asphalt manufactured by bitumen hot mix plant may become aging because of the heating process of aggregates. |
Cold Mix Plant
| The cold mix plant don’t have the heating and drying process of aggregate. |
| The laying of manufactured cold asphalt finished material don’t need to follow the strict temperature limit, and it has strong adaptability due to the cold mix asphalt can adapt changeable climates. |
| The laying of manufactured cold asphalt finished material don’t need to follow the strict temperature limit, and it has strong adaptability due to the cold mix asphalt can adapt changeable climates. |
| Since it does not involve the heating of aggregates, the cold mix asphalt plant will not generate dust and black smoke during the whole production process, thus achieving zero emission. In addition, the produced cold mix asphalt mixture is insoluble in water and will not pollute the nearby water source. Therefore manufactured cold mix asphalt is environmental friendly. |
| There are no factors influencing safety because the cold mix asphalt plant does not involve drying and heating of aggregates. |
| There are no factors influencing safety because the cold mix asphalt plant does not involve drying and heating of aggregates. |
| Since the cold mix asphalt plant does not need to heat the aggregate, the whole production process is environmentally friendly and pollution-free, and the cold mix asphalt can be produced without the approval of the environmental protection department. |
