a: Add the hot melt coating into the hot melt kettle and heat it evenly to the appropriate temperature

 

b: On one side of the laid waterline, the special primer for road shall be uniformly applied to make the road surface and the marking better stick together, and the evaporation of underground water shall be isolated to prevent the marking from falling off after construction.

 

c: The hot melt coating melted to the construction state shall be loaded into the push type construction vehicle, and an appropriate amount of glass beads shall be put into the vehicle body.

 

d: Regulate the flow, and conduct formal construction when the bottom oil is dried to a proper degree. The construction shall be based on the waterline to ensure the construction quality.

 

e: The coating thickness of lane edge line, lane boundary line, guide arrow, road centerline, warning markings, etc. is 1.5-2.0mm, and the thickness of deceleration markings is 5mm. The glass beads on the surface shall be evenly distributed, and the marked lines shall have good visibility, consistent width, equal spacing, even edges, good reflective effect, and firm connection with the road surface.

 

Construction skills of hot melt marking with marking machine

 

As the hot melt marking construction of the marking machine, the powder hot melt marking coating needs to be heated to a high temperature of 180-200 degrees Celsius and melted into liquid before use. For the sake of construction safety, small hot melt marking machines will separate the marking device and the heating equipment for heating and melting paint, which can avoid unnecessary burns and greatly improve the efficiency of melting materials. Generally, the hot melt marking equipment required by the preliminary marking construction team includes: hydraulic double cylinder hot melt kettle, hand push hot melt marking machine, hand push hot melt zebra crossing machine, hand push pre marking machine, etc.

 

Cleaning: During the construction, the construction line shall be marked while cleaning to ensure that there is no throwing, sprinkling, dripping, leakage and pollution, and the equipment is free of oil and water leakage. The construction team shall clean the road surface in the area at a certain distance from the marking line in time to keep the road surface clean and tidy without pollution and damage. Among them, the LXD1200 oil and gas dual cylinder hot melt kettle is recommended to use a hydraulic dual cylinder hot melt kettle. This type of hot melt kettle adopts vehicle design, which is greatly convenient for transportation. At the same time, it has the characteristics of high melting material efficiency, good melting material quality, less fuel use, energy conservation and environmental protection, simple operation, high safety, etc. It is very efficient to cooperate with the manual marking machine for the construction of yellow and white hot melt flat long solid marking lines and short virtual marking lines.

 

The marking materials of Guruike series marking machine shall comply with the provisions of Pavement Marking Paint (JT/T280-2004).

 

(2) The pavement shall be carefully cleaned before the construction of pavement markings. The pavement surface shall be dry and free of dust.

 

(3) The pavement polluted by marking construction shall be cleaned in time to ensure that the pavement is clean.

 

(4) The alignment of the marking line shall be smooth, consistent with the road shape, and the curve shall be smooth. No broken line is allowed.

 

(5) The reflective marking glass beads shall be evenly distributed, firmly attached and evenly reflected.

 

(6) The thickness of the marking line shall be constructed in full accordance with the requirements, and the service time limit shall be ensured.

 

(1) To ensure the quality of the project construction process, carefully review the construction drawings before commencement, prepare the construction organization design according to the actual situation, and after approval, strictly follow the construction organization design.

 

(2) The quality of engineering materials shall be guaranteed. Establish strict material receiving and releasing system. No unqualified materials shall be allowed to enter the site for construction.

 

(3) , control quality from the management system

 

a: All construction personnel shall conduct self inspection.

 

b: The quality inspection shall be conducted once every certain distance of the construction, and the construction supervisor shall personally supervise

 

c: The technical disclosure system shall be implemented, and the technical disclosure must be carried out before the commencement of construction
