Before commencing synchronous chip seal construction, a site survey of the road surface must be conducted to understand its specific condition, such as the degree of damage and traffic flow. This information will help in developing a suitable construction plan and selecting appropriate materials and equipment.
When developing the construction plan, it is necessary to carefully analyze the test data to determine the construction structure, the selection of bonding materials and chip stone, and the treatment methods for existing defects. For defects such as ruts and potholes, repairs are required to ensure sufficient strength and smoothness of the road surface. Simultaneously, asphalt and chip stone preparation must be completed, and personnel and equipment must be properly allocated. This stage requires a comprehensive and detailed plan that fully considers various factors to ensure smooth construction.

Before construction begins, clear construction warning signs should be set up within the construction area. Then, it must be confirmed that the asphalt, chip stone, and supporting equipment are ready, and that the synchronous chip seal machine is in good condition with correct parameter settings. Before commencing construction, on-site tests should be conducted to check the performance of equipment and materials and determine the final construction parameters.
During construction, the road section must first be cleaned to ensure it is free of dust, debris, and other contaminants. Other contaminants should be washed or swept to ensure cleanliness. For areas washed with water, allow the water to completely evaporate and dry before proceeding with construction.
To ensure construction quality, a test section is typically laid, and the working parameters are adjusted based on the results until the desired effect is achieved. Then, continuous construction over long distances can proceed. If construction is done in sections, one section can be opened to traffic. Overlapping joints between sections should be properly treated to ensure a tight and smooth surface.
During construction, manual patching and edge trimming are also necessary. Subsequently, a rubber-tired roller is used for 3-4 passes to ensure a tight bond between the asphalt and aggregate and the road surface. If natural compaction is used, vehicle speed must be restricted. Finally, excess material and loose stones should be cleaned up and recycled.
After construction is completed, curing work is required. When modified asphalt or rubberized asphalt is used as the binder, traffic can be opened after compaction and removal of loose material. If modified emulsified asphalt is used as the binder, traffic should only be opened after it has demulsified, the moisture has evaporated, and it has solidified. During the initial period of operation, traffic should be strictly controlled, limiting vehicle speed and driving behavior to ensure the integrity and safety of the road surface.
