Pavement Crack Filling Adhesive Key Points:

The temperature of the road joint sealant during construction should reach 185°C, but not exceed 204°C.

2) Slot dimensions should meet design requirements, i.e., width ≥ 1cm, depth ≥ 1.3cm.

3) Prior to sealing, the groove and both sides should be kept clean.

4) The road surface temperature during construction should be maintained above 4°C; otherwise, preheating should be conducted.

5) Ensure sufficient cooling time for the pavement crack sealant before opening traffic.

6) During the heating process of pavement joint sealant, ensure even heating by using heating equipment with thermal oil or hot air as the medium to prevent burning. Therefore, when there is no equipment like a hot melt pot that can guarantee uniform heating of the material, do not use a pot for heating asphalt or other open flame heating devices to heat pavement joint sealant.

Road Crack Filling Adhesive Handling and Storage Precautions:

Do not use water when on fire; use carbon dioxide dry powder or foam.

2) Wear protective clothing, safety goggles, or other gear during working hours.

3) Keep children and other non-employees away from heating equipment or hot materials.

4) Store in a dry, cool place.

5) To ensure construction, traffic control should be implemented first, in accordance with the provisions of the "Highway Maintenance Technical Specification" regarding traffic control for highway maintenance operations, and set up cone signs and relocate.

Move the traffic signs vehicle, and assign a dedicated person to direct traffic and promptly relocate construction signs as the project progresses.
