Color Asphalt Spraying Construction Plan

I. Basic Processing:

Firstly, clean and sand the asphalt, removing road dust, floating slurry, oil stains, and standing water, and repair any damaged or defective areas.

2. Protect both curb stones with masking tape prior to construction.

3. Close off traffic prior to construction and cover areas requiring protection, such as curbs, with film.

4. Utilize airless spray machines for colored asphalt coating on road surfaces.

5. It takes about 2 hours to cure at 20°C before it's ready for traffic.

II. Construction Key Points:

Ensure the road surface is intact and clean, free of pollutants and obstructions.

2. Resin mortar can be mixed with appropriate filling material to repair deep potholes or voids in road surfaces.

3. Clean the road surface stains or spots with an appropriate cleaning agent. If washed with water, it must be completely dried.

4. Prior to construction, ensure the road surface is dry. For wet surfaces, use a hot air blower to dry the road, with particular attention to winter or frosty conditions.

5. New asphalt surfaces should be open to traffic for at least 15 days before the installation of colored road surfaces.

6. Large quantities require the use of truck-mounted mechanized construction methods to ensure the quality of work.

7. Typically, traffic is reopened 2 hours after completion of construction to ensure full curing of the asphalt coating agent.

Section 3: Advantages of Asphalt Spraying

High strength: After curing for 48 hours, the compressive strength reaches 53MPa. Therefore, it is robust and wear-resistant, capable of withstanding the long-term rolling of heavy-duty vehicles.

2. Strong Adhesion: Tensile strength of 5.3MPa, 3-4 times that of ordinary materials, and capable of firmly bonding with a variety of substrates such as asphalt, concrete, stone, tiles, and metal.

3. Excellent toughness: Elongation exceeds 40%, maintaining good flexibility at low temperatures.

4. Extended Longevity: Resistant to oil, water, and aging, with a long service life, perfect for outdoor durable use.

5. Environmental Safety: Virtually non-volatile, belongs to VOC-free green materials.

6. Simple and Quick Installation: No special ground treatment required, installation can be completed quickly, with a straightforward process and easier quality control.
