Embodiment 1

[0014] This road paving method includes the following steps:

[0015] A. Pave the white concrete pavement material on the soil roadbed. The white concrete pavement material is made by mixing and mixing the following raw materials: 30 kg of cement, 20 kg of gravel, 15 kg of sand, and 8 kg of admixture. Pave the white concrete pavement material On the dirt road, dry naturally to obtain cement concrete roadbed;

[0016] B. Use the following raw materials to prepare black pavement materials: 30 kg of asphalt, 20 kg of dark silica fume, 13 kg of black iron powder, 10 kg of carbon powder, 25 kg of low-heat cement, 40 kg of sand, 36 kg of water, reduced 12 kg of liquid;

[0017] C. Lay the black pavement material on the cement concrete roadbed and compact it with a roller compactor to a thickness of 5 cm.

[0018] The black pavement material is covered on the side of the cement concrete roadbed.

Embodiment 2

[0020] This road paving method, including the existing cement concrete roadbed, includes the following steps:

[0021] A. Use the following raw materials to prepare black pavement materials: 45 kg of asphalt, 31 kg of dark silica fume, 25 kg of black iron powder, 18 kg of carbon powder, 35 kg of low-heat cement, 50 kg of sand, 45 kg of water, reduced 25 kg of liquid;

[0022] B. Lay the black pavement material on the cement concrete roadbed and compact it with a roller compactor to a thickness of 7 cm;

[0023] The black pavement material is covered on the side of the cement concrete roadbed.

[0024] Asphalt, dark silica fume, black iron powder, carbon powder, low-heat cement and stone sand are mixed to form a black mixture. After adding water and water reducing agent, the mixture becomes a black pavement material. Paved on a white pavement, the white pavement is changed to a black pavement , It eliminates the poor elasticity of the white pavement and is easy to damage; the white pa...

Abstract

The invention discloses a road paving method, relating to the technical field of highway construction. The method adopts a cement concrete roadbed and comprises the following steps: (A) preparing a black pavement material by adopting the following raw materials in parts by weight: 30-45 parts of asphalt, 20-31 parts of deep-color silica powder, 13-25 parts of black iron powder, 10-18 parts of carbon powder, 25-35 parts of low-heat cement, 40-50 parts of stone sand, 36-45 parts of water and 12-25 parts of water reducing agent; and (B) paving the black pavement material on the cement concrete roadbed, and compacting by a rolling machine, wherein the paving thickness is 5-7 centimeters. The road paving method is used for changing a white pavement into a black pavement; and compared with the prior art, the road paving method has the advantages of solving the problems that the white pavement is poor in elasticity, poor in visual effect and easy to cause traffic accidents.

Description

Technical field [0001] The invention relates to the technical field of highway construction, in particular to a road paving method for transforming a white pavement into a black pavement. Background technique [0002] The white pavement is the abbreviation of cement concrete pavement. The white pavement has a cement concrete roadbed and a cement concrete pavement laid on the cement concrete roadbed; this white pavement has the following problems during use: 1. The pavement has poor elasticity after laying and is easy to Damage; 2. The visual effect of pavement with marking lines is poor after paving, and it is easy to cause visual fatigue; 3. The road has poor absorption of light, resulting in reflections that cause people to feel dazzling, which may easily cause traffic accidents. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a road paving method, which can solve the problems that the white road surface has poor elasti...
