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

Road pavement method

Technical field

The present invention relates to highway construction technology field, especially a kind of road that dark-coloured pavement is transformed into for white pavement Laying method.

Background technology

White pavement is the abbreviation of cement concrete pavement, and white pavement has cement concrete roadbed and is laid on the water Cement concrete pavement on cement concrete roadbed；There is problems with use in this white pavement：1. after laying Road surface elasticity is poor, is easily damaged；2. lay after road surface mix markings visual effect it is poor, easily cause visual fatigue；3. Road surface is poor to light absorption, produce it is reflective cause people to feel to dazzle the eyes, so as to easily cause vehicle accident.

The content of the invention

The technical problem to be solved is to provide a kind of road pavement method, and it can solve white pavement elasticity Poor, poor visual effect easily causes the problem of vehicle accident.

In order to solve the above problems, the technical solution adopted in the present invention is：A kind of road pavement method, including cement is mixed It is solidifying earth roadbed, comprise the following steps：

A. black pavement material is prepared using the raw material of following weight portion：30 parts ~ 45 parts of Colophonium, dark silica flour 20 parts ~ 31 Part, 13 parts ~ 25 parts of black iron powder, 10 parts ~ 18 parts of carbon dust, 25 parts ~ 35 parts of low-heat cement, 40 parts ~ 50 parts of stone sand, water 36 parts ~ 45 Part, 12 parts ~ 25 parts of water reducer；

B. the black pavement material is routed on the cement concrete road bed, is compacted with chaser, laying is thick Spend for 5 centimetres ~ 7 centimetres；

In above-mentioned technical proposal, more specifically technical scheme can also be：The black pavement material covers the cement The side of way of concrete foundations.

As a result of above-mentioned technical proposal, the present invention has the advantages that compared with prior art：

1. dark silica flour has comprcssive strength, impermeability, frost resistance, wear resistence and a corrosion stability, durability and

Adhesion strength is higher；Black iron powder has higher comprcssive strength, and dark silica flour and black ferrum are added in Colophonium On the one hand black pavement material obtained in powder can strengthen the elasticity on road surface using Colophonium as material so that road surface not rapid wear It is bad；Another aspect road surface color becomes black, solves the problems, such as that white pavement poor visual effect easily causes vehicle accident.

2. the present invention improves the comprcssive strength and adhesion strength of black pavement material, adds low-heat cement and the water reducer can be with So that reducing the probability that crack occurs in road surface after black pavement material laying.

Specific embodiment

Below in conjunction with specific embodiment, the invention will be further described：

Embodiment 1：

This road pavement method, comprises the following steps：

A. white concrete ground surface material is set on soil roadbed upper berth, the white concrete ground surface material is stirred by following raw material Mix and be mixed to prepare：30 kilograms of cement, 20 kilograms of rubble, 15 kilograms of sand, 8 kilograms of additive, by the white concrete road surface material Material is routed on dirt road, and natural drying obtains cement concrete roadbed；

B. black pavement material is prepared using the raw material of following weight portion：30 kilograms of Colophonium, 20 kilograms of dark silica flour, black 13 kilograms of iron powder, 10 kilograms of carbon dust, 25 kilograms of low-heat cement, 40 kilograms of stone sand, 36 kilograms of water, 12 kilograms of water reducer；

C. the black pavement material is routed on the cement concrete roadbed, is compacted with chaser, laying depth For 5 centimetres.

The black pavement material is covered into the side of the cement concrete roadbed.

Embodiment 2：

This road pavement method, including existing cement concrete roadbed, comprise the following steps：

A. black pavement material is prepared using the raw material of following weight portion：45 kilograms of Colophonium, 31 kilograms of dark silica flour, black 25 kilograms of iron powder, 18 kilograms of carbon dust, 35 kilograms of low-heat cement, 50 kilograms of stone sand, 45 kilograms of water, 25 kilograms of water reducer；

B. the black pavement material is routed on the cement concrete roadbed, is compacted with chaser, laying depth For 7 centimetres；

Colophonium, dark silica flour, black iron powder, carbon dust, low-heat cement and stone sand are mixed into black mixture, add water and subtract Become black pavement material after water preparation mixing, be laid in white pavement, make white pavement into dark-coloured pavement, eliminate white The road surface elasticity that road surface is present is poor, is easily damaged；White pavement visual effect after laying is poor；Easily produce vehicle accident Problem.

Claims

1. a kind of road pavement method, including cement concrete roadbed, it is characterised in that comprise the following steps：

A. black pavement material is prepared using the raw material of following weight portion：30 parts ~ 45 parts of Colophonium, 20 parts ~ 31 parts of dark silica flour is black 13 parts ~ 25 parts of color iron powder, 10 parts ~ 18 parts of carbon dust, 25 parts ~ 35 parts of low-heat cement, 40 parts ~ 50 parts of stone sand, 36 parts ~ 45 parts of water subtracts 12 parts ~ 25 parts of water preparation；

B. the black pavement material is laid on the cement concrete road bed, is compacted with chaser, laying depth is 5 Centimetre ~ 7 centimetres.

2. road pavement method according to claim 1, it is characterised in that：The black pavement material covers the cement The side of way of concrete foundations.
