Problems solved by technology

The sand-containing mist sealing technology uses a large amount of mist sealing materials. In order to avoid insufficient friction coefficient, some sand particles are added during the mist sealing operation. However, this method still cannot avoid the shiny wheel marks and the attenuation of the friction coefficient after opening to traffic. question
The coal tar-based blackening method has strong adhesion with old asphalt, but the coal tar component is highly toxic and volatile, and it is easy to cause poor waterproof and sealing durability. It has been banned by developed countries such as the United States. Not good for skid resistance on the road surface

Embodiment 1

[0041] Weigh each component to prepare water-based maintenance agent for asphalt pavement: 60 kg of tall oil, 8 kg of kerosene, 570.5 kg of IndulinAA, 0.6 kg of RedicoteE-48750.6 kg, 0.9 kg of lauryl polyoxyethylene ether, 2 kg of hydrochloric acid, 80 kg of water Kilogram.

[0042]Indulin AA57, RedicoteE-4875, lauryl polyoxyethylene ether, hydrochloric acid and water are first reconciled into an emulsified soap liquid, and the other components are heated to 60°C to a flow state, and passed through a high-speed rotating colloid mill together with the emulsified soap liquid to obtain the example 1 asphalt pavement water-based maintenance agent.

[0043] Weigh each component to prepare water-based protective agent for asphalt pavement: 70 kg of Donghai 70# asphalt, 20 kg of SBS modified asphalt, 6 kg of Indulin1468 latex, 90.5 kg of RedicoteE-90.5 kg, 0.5 kg of IndulinDF6, and 100 kg of water. The SBS modified asphalt in the examples of the present invention is DT307 produced b...

Embodiment 2

[0047] The asphalt pavement water-based maintenance agent in Example 1 was replaced by: 60 kg of tall oil, 8 kg of kerosene, 1.1 kg of Indulin AA, 0.9 kg of lauryl polyoxyethylene ether, 2 kg of hydrochloric acid, and 80 kg of water.

[0048] Others are the same as embodiment 1.

Embodiment 3

[0050] The asphalt pavement water-based maintenance agent in Example 1 was replaced with: 60 kg of tall oil, 8 kg of kerosene, 1.1 kg of Redicote E-4875, 0.9 kg of lauryl polyoxyethylene ether, 2 kg of hydrochloric acid, and 80 kg of water.

[0051] Others are the same as embodiment 1.

Abstract

The invention relates to an asphalt pavement waterborne paint double-layer spraying method. The method is characterized by including the steps of: (1) pavement cleaning and drying; (2) asphalt pavement waterborne maintenance agent spraying and preservation absorption for over 2h; and (3) asphalt pavement waterborne protective agent spraying, drying and curing. The method provided by the invention has the characteristics of simple and convenient construction process, no need for special construction equipment, and no pollution or emission, and at the same time finishes reduction self-sealing of asphalt pavement surface non-structural micro-cracks and surface layer black protective film sealing. When the project is completed, the asphalt pavement can be open to traffic immediately.

Description

technical field [0001] The invention belongs to the technical field of asphalt pavement maintenance, and in particular relates to a double-layer spraying method of water-based paint on asphalt pavement. Background technique [0002] Over the past two decades, China's road network, especially the high-grade road network, has developed beyond the ordinary. At present, the highway industry is in the period of transformation from large-scale construction to road network management and maintenance, and the maintenance of asphalt pavement maintenance and service level is becoming the main industry goal. On the other hand, the status quo is that the maintenance of asphalt pavement is still relatively extensive, with high cost and large resource consumption. For the road industry to develop sustainably, it is the general trend to develop road property preservation technologies such as road surface preventive maintenance technology, and it is also the choice of developed countries. ...
