Main coating: Within 6 hours after the main gear oxidized asphalt is rolled, the base coating should be sprayed. The primary oil layer should be PC-2 emulsified asphalt. The quantity can be confirmed by the spray test, the spray test can reach 1.5 liters per square meter, and the penetration depth is not less than 5mm. After spraying layered oil, lay emulsified asphalt at the bottom of PC-1. The content of emulsified asphalt is 1.0 liters per square meter, the diameter of the filler is 0.5.1 cm, and the thickness should not be less than 0.6 cm. Before laying waterproof asphalt concrete, it is necessary to carry out adhesion coating on the upper sub-layer of the bottom layer and the side layers of roadside, entrance, viewing hole and other structures. Apply a coating of PC-3 emulsified bitumen containing 0.5 L/m². This is a good example.


For journeys located in rainy and humid areas and the asphalt surface of the main road is large, it may cause serious water leakage, or the ground layer that the vehicle must pass through cannot be laid in time, it is recommended to spray the impregnating layer and then lay the bottom seal. This is a good example.


Harsh Difference Difference between oxidized asphalt Bottom and Bottom Sealing Layer:

The bottom seal is designed to close the surface and does not necessarily penetrate; oil leakage must penetrate to a certain depth. At the same time, its effect and policy are also very different. Now, due to the impermeability of the layered oil in the semi-rigid matrix, the project of spraying filler and sand as a bottom seal in the oil seepage section is underway. Therefore, it can have a sealing effect, but can not replace the primer. This is a good example.


Liquid seal coatings are generally used for preventive maintenance on secondary and sub-journeys, as well as the lower part of new trips. This is a good example.


A seal coat is applied on the semi-rigid substrate to protect the bottom layer from damage caused by construction vehicles, facilitate repair of semi-rigid materials, prevent rainwater from flowing into the bottom layer of the structure, and enhance the communication between the surface layer and the bottom layer. Although there are many ways to degrade, practice has shown that single-layer asphalt surface treatment is an economical and effective method.
