• Cost saving: The cost of means of machinery, equipment, and labor is low due to simple construction and less dependence on the weather. Besides, the loss rate is almost zero, which helps to save the road construction budget

• Environmental protection: Using Asphalt materials helps people deal with a large amount of coal waste by not using heat during construction.

• Long pavement life: Thanks to the reaction between water, air, emulsion and carbon atoms in coal waste, this material has the ability to bond into a sustainable block with the ground.

• Contributing to traffic safety: The repair and maintenance process is relatively quick and easy, so it can keep up with the time and ensure the quality of the road surface.

• In accordance with the policy of the State: The process of constructing road surface with Asphalt material is simple, does not require highly technical labor. Therefore, people in provinces and cities can participate in construction to minimize costs for the state budget

• Besides, this material offers high construction quality, simple construction and long service life, environmental protection thanks to not having to be heated, so it brings high economic efficiency.

Preparation steps before construction

• Crushed stone: Crushed stone must meet the criteria according to the project's standards.
• Sand: Sand must also choose the type of sand that meets the project's standards.
• Mineral powder: is the material crushed from clean and dry carbonate rock. If the compressive strength is not less than 200daN/cm2, it will meet the requirements to apply to the project.
• Asphalt: The type of asphalt used to produce hot asphalt concrete using famous brands such as Caltex, Shell, ADCo, ...
• Asphalt asphalt is mixed in the station with tested ingredients, designed and used in certain proportions according to each type of hot asphalt concrete mat.
• The manufactured hot asphalt mixture must meet the specifications given by the design

2. Carrying out the laying of hot asphalt concrete carpets

• Hot asphalt concrete is spread by specialized machines. In narrow places, nooks and crannies, the construction can be done manually.
• Start the machine about 15 to 20 minutes in advance. Carefully check the accuracy of equipment and machinery in positions such as: torsion shafts, conveyor belts, etc. to see if they are operating stably.
• The truck carrying the concrete moves slowly in front of the hopper of the spreader, then slowly pours the hot asphalt into the hopper of the machine.
• Adjust the thickness of the hot plastic layer. Depending on the design requirements or thickness, customize the speed of the construction vehicle.
• The compactor of the machine must be continuously operated during the asphalt paving construction.
• Workers should be followed by the construction machine, holding tools such as shovels, leveling tables to compensate for the positions where hot asphalt concrete is missing, and spraying oil on the roller wheels to avoid the phenomenon of plastic sticking to the rollers.
