Embodiment 1

[0028] Please refer to the attached figure 1 , A road construction method, the road construction method here is suitable for 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 the roadbed1.

[0031] Specifically, before filling the foundation of the road section, the current pile of soil, demolition of construction waste and the current cement pavement are all excavated, transported and removed, and the underlying weeds, tree roots, etc., the original ground weeds, tree roots, crop residues, and rot All soil, garbage, etc. must be removed; on this basis, the entire road section shall be cleared.

[0032] Step b:

[0033] The first pond slag treatment layer 2a and the second pond slag treatment layer 2b are sequentially laid on the top of the roadbed 1. The thickness of the first pond slag treatment layer 2a and the second pond slag treatment layer 2b are both 40 cm.

Embodiment 2

[0050] Please refer to the attached figure 2 , A road construction method, the road construction method here is suitable for road construction methods at the intersection of sidewalks and non-motorized vehicle lanes.

[0051] Step a:

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

[0053] Specifically, before filling the foundation of the road section, the current pile of soil, demolition of construction waste and the current cement pavement are all excavated, transported and removed, and the underlying weeds, tree roots, etc., the original ground weeds, tree roots, crop residues, and rot All soil, garbage, etc. must be removed; on this basis, the entire road section shall be cleared.

[0054] The thickness of the first pond slag treat...

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 field of construction technology, and more specifically, it relates to a road construction method. Background technique [0002] With the rapid development of my country's national economy, the state has invested more and more in infrastructure construction. The development of highway construction is an important way to promote the integration of urban and rural economy. However, with the continuous increase of highway 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 were urgently needed to improve them. In recent years, the introduction of asphalt concrete technology has greatly improved the paved roads. As asphalt concrete construction is faster, maintenance is easier, and noise and dust are relatively low when driving. In view of such advantages, it is now widely used in road construction. However, du...
