Before construction of the slurry sealing truck, the oil pump, water pump system and oil (emulsion) and water pipelines on the machine should be checked to see if there are any faults in the control valves; start and stop tests should be carried out on each part of the machine to check whether the operation is Normal; for sealing machines with automatic control functions, use automatic control to operate the air transport; to check the sequential linkage between various components; after the overall machine operation is normal, the feeding system on the machine must be calibrated.

The base layer must be cleaned to ensure that the top surface of the base layer is clean and there is no accumulation of water before starting the permeable oil construction. Before paving with permeable oil, attention should be paid to marking the cracking locations of the base layer (fiberglass gratings can be laid to reduce the hidden danger of cracking of the asphalt pavement in the future).

Acceptance at the grassroots level, inspection of materials, machinery and equipment. Check the flatness of the base layer and require all indicators to meet construction standards; check the source, quantity, quality, storage conditions, etc. of raw materials; check the performance and measurement accuracy of construction equipment to ensure normal use of functions.

In asphalt pavement construction, emulsified bitumen is generally used as sticky layer asphalt material. When using emulsified bitumen, it is advisable to use fast-breaking emulsified bitumen, or fast and medium-setting liquid petroleum asphalt or coal asphalt.

The general principle of bag dust collector design is economy and practicality. It should be neither too large nor too small. The design premise must be to meet the dust emission standards stipulated by the country.

sinosun special pulse bag filter (pulse dust collector) for asphalt mixing plant has the advantages of large air volume, high purification efficiency, small footprint, small filter bag wear, long service life, simple replacement of filter bags, and convenient maintenance.
