Abstract

The invention relates to the technical field of highway construction, in particular to an asphalt highway construction method. The method comprises the following steps: S1, a pre-construction stage: carrying out line measurement and lofting and carrying out roadbed construction at the same time; S2, asphalt mixture mixing: mixing the filling aggregate and asphalt, and transporting the mixed material to a to-be-constructed area; S3, pavement construction: paving a mixture with the same particle size on the roadbed constructed in S1, and pressing the paved mixture by using a road pressing machine to form an asphalt pavement; and S4, road surface auxiliary construction: performing lane line, expansion joint and lane arrow construction on the asphalt road surface formed in the step S3. The asphalt mixture adopted by the invention is high in strength, has excellent high-temperature heavy load resistance, bending resistance and crack resistance, is greatly improved in fatigue performance and durability, and is good in construction fluidity, small in void ratio and long in service life. Meanwhile, the technical defect that the thickness of the asphalt pavement is not uniform is overcome through the arrangement.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to an asphalt road construction method. Background technique [0002] Asphalt pavement is 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. Asphalt binder bonds the mineral aggregates into a whole, increases the strength and enhances the ability of the pavement to resist driving damage, and makes the pavement water-resistant. The asphalt materials suitable for road construction are mainly petroleum asphalt and coal asphalt. [0003] In the prior art, during asphalt road construction, the asphalt concrete that has been mixed will be spread to the construction area, and then...
