Embodiment 1

[0028] Please refer to the attached figure 1 , a road construction method, the road construction method here is applicable to the construction method of motor vehicle lanes and non-motor vehicle lanes.

[0029] Step a:

[0030] Clean up and level the road surface that needs to be paved, and fill it with pond slag to form a roadbed 1 .

[0031] Specifically, before filling the foundation of the road section, the existing soil, demolition and construction waste, and the existing cement pavement are all excavated and removed, and the underlying weeds and tree roots are eliminated. Weeds, tree roots, crop residues, and rotting All soil and garbage must be removed; on this basis, the entire road section should be cleared.

[0032] Step b:

[0033] The first pond slag treatment layer 2a and the second pond slag treatment layer 2b are successively laid on the top of the roadbed 1, and the thicknesses of the first pond slag treatment layer 2a and the second pond slag treatment laye...

Embodiment 2

[0050] Please refer to the attached figure 2 , a road construction method, the road construction method here is applicable to the road construction method at the intersection of sidewalks and non-motor vehicle lanes.

[0051] Step a:

[0052] Clean up and level the road surface that needs to be paved, and form the first subgrade 111 for pond slag filling on the road surface where the non-motor vehicle lane is located; pave the first pond slag treatment layer 2a and the second pond slag treatment layer at the non-motor vehicle lane 2b.

[0053] Specifically, before filling the foundation of the road section, the existing soil, demolition and construction waste, and the existing cement pavement are all excavated and removed, and the underlying weeds, tree roots, etc. All soil and garbage must be removed; on this basis, the entire road section should be cleared.

[0054] The thicknesses of the first pond residue treatment layer 2 a and the second pond residue treatment layer ...

Abstract

The invention discloses a road construction method, and solves the problems that asphalt road surfaces are frequent in cracking, low in intensity and poor in stability because of non-standard construction of many regions. The road construction method is characterized by adopting the technical scheme comprising the following steps of (a), cleaning and levelling a road surface of a road requiring paving, and forming a roadbed for pond residues to fill and pave; (b), sequentially paving a first pond residue processing layer and a second pond residue processing layer; (c), grinding macadam materials to form a macadam cushion layer of which the crushing value is 30%, and paving the macadam cushion layer on the second pond residue processing layer; (d), paving a cement stabilizing crushed stone layer of which the cement content is 3-6%; (e), uniformly sprinkling petroleum asphalt of which the consumption is 1.2 Kg / m<2>, then sprinkling aggregates, and immediately grinding the aggregates by a road roller to form a lower sealing layer; and (f), paving an asphalt mixed material layer of which the void percentage is 3-6%. The road construction method disclosed by the invention has the advantages of being high in strength, not liable to crack and strong in durability.

Description

technical field [0001] The invention relates to the technical field of construction, more specifically, it relates to a road construction method at the junction of sidewalks and bicycle lanes. Background technique [0002] With the rapid development of my country's national economy, the country's investment in infrastructure construction is also increasing. The development of highway construction is an important way to promote the integration of urban and rural economies. However, with the continuous increase of road construction mileage, the quality of road construction has gradually become the focus. Many roads in the past were difficult to meet the requirements, and new technologies are urgently needed to improve them. In recent years, asphalt concrete technology has been introduced, which has greatly improved the paved roads. Asphalt concrete construction is faster, maintenance is easier, and the noise and dust are relatively low when driving. In view of these advantag...
