Embodiment 1

[0025] The present invention provides a kind of asphalt laying technology for road construction, it comprises the following steps,

[0026] S1 Clean up the roadbed and level it; after clearing out the sundries on the road surface, level it.

[0027] S2 laying a cushion; the cushion is processed from the asphalt surface material after washing and planing of the old asphalt pavement. The cushion layer is paved and rolled on the roadbed in step S1.

[0028] S3 lays a braided mesh layer; the braided mesh layer of S4 is a stainless steel braided mesh layer, which plays a supporting role and increases strength.

[0029] S4 paves the first asphalt layer; the first asphalt layer in S4 includes the following components by weight: 75 parts of petroleum asphalt, 10 parts of antioxidant and 15 parts of filler for the first asphalt layer. The first asphalt layer filler includes blast furnace slag powder, limestone powder and calcium carbonate powder, the mass ratio of which is 12:6:7, th...

Embodiment 2

[0033] The present invention provides a kind of asphalt laying technology for road construction, it comprises the following steps,

[0034] S1 Clean up the roadbed and level it; after clearing out the sundries on the road surface, level it.

[0035] S2 laying a cushion; the cushion is processed from the asphalt surface material after washing and planing of the old asphalt pavement. The cushion layer is paved and rolled on the roadbed in step S1.

[0036] S3 lays a braided mesh layer; the braided mesh layer of S4 is a wire braided mesh layer, which plays a supporting role and increases strength.

[0037] S4 paves the first asphalt layer; the first asphalt layer in S4 includes the following components by weight: 70 parts of petroleum asphalt, 15 parts of antioxidant and 10 parts of filler for the first asphalt layer. The first asphalt layer filler includes blast furnace slag powder, limestone powder and calcium carbonate powder, the mass ratio of which is 15:5:8, the particle ...

Embodiment 3

[0044] The present invention provides a kind of asphalt laying technology for road construction, it comprises the following steps,

[0045] S1 Clean up the roadbed and level it; after clearing out the sundries on the road surface, level it.

[0046] S2 laying a cushion; the cushion is processed from the asphalt surface material after washing and planing of the old asphalt pavement. The cushion layer is paved and rolled on the roadbed in step S1.

[0047] S3 lays a braided mesh layer; the braided mesh layer of S4 is a wire braided mesh layer, which plays a supporting role and increases strength.

[0048] S4 paves the first asphalt layer; the first asphalt layer in S4 includes the following components by weight: 80 parts of petroleum asphalt, 5 parts of antioxidant and 20 parts of filler for the first asphalt layer. The first asphalt layer filler includes blast furnace slag powder, limestone powder and calcium carbonate powder, the mass ratio of which is 10:8:5, the particle s...

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to an asphalt laying process for road construction. Background technique [0002] Asphalt pavement is one of the more common road surfaces. Asphalt pavement is a soft road surface, which is relatively soft and comfortable. With the help of the elasticity of the road surface and the vehicle's own shock absorber system, both passengers and drivers are more comfortable during driving. The advantages of asphalt pavement are: smooth surface, no joints, comfortable driving, low vibration, low noise, wear-resistant, no dust and easy to clean, short construction period, easy maintenance and repair, renewable utilization, suitable for phased construction, etc. However, asphalt pavement has the defect of poor temperature stability, and it is necessary to improve the paving materials and laying technology to improve the performance of asphalt pavement.
