Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: high-grade highways are usually used for long-distance transportation, so the frequency of high-load trucks traveling on the highway is relatively frequent, especially in the case of serious overloading, the concrete road surface is easily subjected to large loads. Cracking and breaking, once the road surface is cracked or broken on the expressway, the road surface will no longer be smooth, which may cause fast-moving vehicles to roll over and cause serious safety accidents. Therefore, there is still room for improvement.

Embodiment 1

[0075] refer to figure 1 , a concrete slurry, the preparation method of the concrete slurry is as follows:

[0076] S01. Add 100kg of Portland cement, 90kg of water, and 11kg of water reducing agent into the stirring tank at a rotating speed of 90r / min, and stir for 3min to form cement slurry;

[0077] S02. Add 25 kg of picoxystrobin, 2 kg of ethyl cinnamate, and 2 kg of methyl cinnamate to the cement slurry, and stir at a speed of 60 r / min for 8 min to form a premix;

[0078] S03. Add 250kg of fine aggregate and 300kg of coarse aggregate to the premix at a speed of 45r / min, and stir for 10 minutes to form a concrete slurry at a speed of 20r / min, and continue stirring until it is used up.

Embodiment 2

[0080] refer to figure 1 , a concrete slurry, the preparation method of the concrete slurry is as follows:

[0081] S01. Add 100kg of Portland cement, 100kg of water, and 10kg of water reducing agent into the stirring tank at a rotating speed of 90r / min, and stir for 3min to form cement slurry;

[0082] S02. Add 27.5kg of picoxystrobin, 2.5kg of ethyl cinnamate, and 2.5kg of methyl cinnamate to the cement slurry, and stir at a speed of 60r / min for 8min to form a premix;

[0083] S03. Add 275kg of fine aggregate and 325kg of coarse aggregate to the premix at a speed of 45r / min, and stir for 10 minutes to form a concrete slurry at a speed of 20r / min, and continue stirring until it is used up.

Embodiment 3

[0085] refer to figure 1 , a concrete slurry, the preparation method of the concrete slurry is as follows:

[0086] S01. Add 100kg of Portland cement, 110kg of water, and 9kg of water reducing agent into the stirring tank at a rotating speed of 90r / min, and stir for 3min to form cement slurry;

[0087] S02. Add 30 kg of picoxystrobin, 3 kg of ethyl cinnamate, and 3 kg of methyl cinnamate to the cement slurry at a speed of 60 r / min and stir for 8 min to form a premix;

[0088] S03. Add 300kg of fine aggregate and 350kg of coarse aggregate to the premix at a speed of 45r / min, and stir for 10 minutes to form a concrete slurry at a speed of 20r / min, and continue stirring until it is used up.

Abstract

The invention relates to the technical field of pavement construction, in particular to a concrete pavement construction method which comprises the following steps: S1, excavating a trench; s2, compacting the bottom of the trench, then laying a reinforcing net at the bottom of the trench, and backfilling and compacting then soil is backfilled; s3, laying a base layer at the bottom of the trench; s4, laying a cushion layer on the base layer; s5, laying a reinforcing net on the cushion layer; s6, pouring a concrete surface layer on the cushion layer, wherein the concrete surface layer is formedby pouring concrete grout, and the concrete grout comprises the following components in parts by mass: 100 parts of Portland cement; 250 to 300 parts of fine aggregate; 300 to 350 parts of coarse aggregate; 25 to 30 parts of picoxystrobin; 2 to 3 parts of ethyl cinnamate; 2 to 3 parts of methyl cinnamate; and 90-110 parts of water. The method has the effects that the concrete pavement is high in stability and not prone to cracking and breaking, and the driving safety is high.

Description

technical field [0001] The invention relates to the technical field of road surface construction, in particular to a concrete road surface construction method. Background technique [0002] At present, with the development of society, there are more and more vehicles, and the demand for roads is getting stronger and stronger. Roads are mainly divided into two types: concrete pavement and asphalt pavement. [0003] Existing concrete pavement roads are more suitable for vehicles to run fast because of their smooth surfaces, and are often used on high-grade roads, such as expressways. [0004] The above-mentioned existing technical solutions have the following defects: high-grade highways are usually used for long-distance transportation, so the frequency of high-load trucks traveling on the highway is relatively frequent, especially in the case of serious overloading, the concrete road surface is easily subjected to large loads. As for cracking and breaking, once the road sur...
