The invention provides a multifunctional composite melt blown nonwoven fabric and a preparation method thereof. Firstly, the principle of polypropylene modification reaction extrusion is used to mix the initiator, fluorine-containing olefin monomer and polypropylene according to a certain mass ratio, and then undergo melt grafting modification through a twin-screw extruder to prepare a high-strength Flowable modified polypropylene material. Then melt-blown grade polypropylene and modified polypropylene are subjected to double-layer melt-blown spinning and composite web laying to prepare a multifunctional composite melt-blown nonwoven fabric. The invention combines conventional polypropylene non-woven fabric with fluorine-containing graft modified polypropylene non-woven fabric through double-layer melt blown to obtain gradient electret filter material. The electret effect and charge stability are improved by adjusting the chain segment composition of the fluorine-containing graft-modified polypropylene. The non-woven fabric prepared by the invention has the advantages of good electrostatic electret effect, high air filtration efficiency, low pressure resistance and the like.

The invention discloses a method for paving a combined base asphalt pavement, which belongs to the technical field of road paving. The pavement structure includes a base structure and an asphalt surface layer, which is characterized in that the base structure is composed of an asphalt mixture viscoelastic anti-fatigue cushion layer, a semi-rigid lower base layer and an upper base layer, and the elastic anti-fatigue buffer layer, semi-rigid lower layer The base layer and the upper base layer are laid on the roadbed from bottom to top. Compared with the prior art, the pavement structure pavement method of the present invention reduces the damage of the semi-rigid base due to voiding of the roadbed and uneven stress by setting the asphalt mixture viscoelastic anti-fatigue cushion layer under the semi-rigid base , while improving the anti-fatigue performance of the semi-rigid base; setting the upper base on the semi-rigid base improves the ability of the pavement structure to resist reflection cracks, greatly prolongs the service life of the pavement structure, and effectively avoids structural damage to the pavement in a short period of time. It can reduce the thickness of the semi-rigid base and reduce the consumption of building materials such as cement and sand.
