Abstract

The invention discloses a protective film material for asphalt pavement during road construction. The protective film material sequentially comprises a first polyethylene terephthalate (PET) layer, afirst styrene-butadiene-styrene (SBS) layer, a second PET layer, a first styrene-isoprene-styrene (SIS) layer, a first polyethylene layer, a second polyethylene layer, a second SBS layer and a third PET layer from inside to outside, wherein the first PET layer has a first melt flow rate based on ASTM-D-1238 test, the first SBS layer has a second melt flow rate based on ASTM-D-1238 test, the secondPET layer has a third melt flow rate based on ASTM-D-1238 test, the first SIS layer has a fourth melt flow rate based on ASTM-D-1238 test, the first polyethylene layer has a fifth melt flow rate based on ASTM-D-1238 test, the second polyethylene layer has a sixth melt flow rate based on ASTM-D-1238 test, the second SBS layer has a seventh melt flow rate based on ASTM-D-1238 test, and the third PET layer has an eighth melt flow rate based on ASTM-D-1238 test. The protective film material disclosed by the invention is good in tear resistance and high in heat sealing strength and can well protect an asphalt construction pavement.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a protective film material used for road construction asphalt pavement and a road construction method. Background technique [0002] Asphalt pavement refers to various types of pavement paved with asphalt materials mixed with mineral materials. Asphalt binder improves the ability of paving aggregates to resist road damage from driving and natural factors, making the road smooth, less dusty, impermeable and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction. [0003] Prior art CN109016716A discloses a high-barrier strength cross film, which includes: HDPE layer, HDPE and first color masterbatch mixed layer, HDPE and second color masterbatch mixed layer, adhesive layer, HDPE layer from top to bottom , HDPE and the first color masterbatch mixing layer, HDPE and the second color masterbatch mixing layer, PVA coating layer...
