Hot asphalt (also known as Asphalt Concrete) is composed of gravel mixture includes: stone, sand, mineral powder and asphalt, which is used mainly for road surface structure produced in mem.Duoc Hot asphalt plant.
The production process of hot asphalt:
- Produced at the hot asphalt plant.
- Materials are transported to and weighed by electronic weighing systems to ensure accuracy, small error.
- Then, the material such as large rocks, medium rocks, small rocks, sand, dry additives are mixed together in the mixing chamber are included.
- Range of about 20s mix asphalt is sprayed hidden in mist spray mixed with other materials, the paddle of the mixing chamber continued agitation for about 25-30s, then down through the outfall discharge data of the mixing chamber.
Classification: Concrete asphalt but popular include the following categories:
- Hot asphalt often: A mixture of aggregate (crushed stone, sand, mineral powder) and a binder (bitumen 60/70) were mixed together in a homogeneous certain percentage in temperature conditions allow. Asphalt concrete mixture used to carpet the road-surfacing of protectionism aimed at lowering avoid direct impacts from the environment and transport.
- Hot Plastic Polymer Concrete: A special type of asphalt concrete composition as asphalt binder polymer, is designed in 22 BC 356-06 standard aims to improve certain characteristics of concrete work conventional asphalt for applications in the transportation category with high technical requirements.
Asphalt Concrete
Process hot asphalt concrete carpet:
1. Sprinkle the pilot.
2. Construction of asphalt concrete.
3. Rolling asphalt concrete mixtures.
Technical standards:
Concrete products Plastic Welding Hot Vietnam always be tested through rigorous process of monitoring, inspection and testing directly in the technical department at the factory and engineering research department of the company. Therefore the products leaving the factory are satisfied the technical requirements and the quality of which:
- Satisfying the requirements of the Vietnam Standards (ISO), American Standard (ASTM) and British Standards (BS)
- Always ready to meet other technical requirements of the customer.
- Production management system and supply of concrete conforms to ISO 9001: 2008
