1. Bottom cleaning: The asphalt layer is generally sodium asphalt sulfonate selected after all other operations are completed to prevent surface damage and pollution. At the same time, before laying, ensure that the bottom concrete is clean and meet the drainage slope requirements.

2. Oil layer spraying: Pay attention to the protection of the product when spraying the oil layer, and the spraying should be uniform and abundant.

When laying soil asphalt: When laying a large volume layer, it is necessary to maintain a stable spraying speed and quantity. When laying mixed materials, the distance should not be too large, and the thickness must be uniform, and the number of grinding should not be less than 3 times to ensure that the mixture is not vacancy. In general, the larger layer cannot be aggregate.

4. Surface layer asphalt: After laying a rough layer, it is assumed that the rainwater causes wet and monotonous ground, and it is not possible to continue to lay a thin layer. It is necessary to ensure that the road surface is completely monotonous to prevent affecting the viscosity. When spraying the asphalt composition on the surface, it is necessary to control the direction and height of the drainage during the heat treatment of the blanking.

5. Patching: As the asphalt release time must be the same during paving, there will inevitably be gaps. It is necessary to ensure strict sodium asphalt sulfonate horizontal connection and dredging. Every time the paving is covered by the remaining asphalt, it is necessary to shovel by hand in time. Causes the paving to be re-laid from scratch.

6. Pressing the margin: After the asphalt concrete pallet is flattened, it is necessary to press the margin in time while it is hot, and use a small vibration motor to flatten the margin, which can be quickly leveled. Marginal Marginal Marginal Orientation Manual Correction.

7. Pressure: Our special term includes three stages: pressure at the top, pressure and pressure after all. The direction of motion of the roller should be parallel to the centerline of the journey. The curved surface is smooth and dense, and the arch arms coincide with the curved surface.

Product Protection: After laying asphalt for 1-2 days (assuming hot summer, the monotonous time will be shortened, depending on the time of the year for good absorption), monotonous surface, tape should be applied immediately after monotony, and before complete completion Prepare the soil for coating.

Generally, when the surface temperature is lower than 50 degrees Celsius, it can be opened to the partner.If you have any other questions, please contact us for sodium asphalt sulfonate details or contact us directly.
