Embodiment 1

[0028] Select 100 parts of heavy traffic road asphalt AH-70 decolorized asphalt and heat it to a fluid state at 100°C, add 10 parts of force-sensing material and 10 parts of reinforcing agent under stirring conditions (speed 200rpm), and stir for 40 minutes to obtain mechanochromic asphalt materials, stored for later use.

[0029] When mixing, heat the mesochromic asphalt material to 170°C, heat the stone material graded as AC-13 to 155°C, and then mix the asphalt and stone material; during construction, spread the mixed asphalt and stone material on the road surface On, control the temperature at 140°C for compaction treatment.

Embodiment 2

[0031] Select 100 parts of heavy traffic road asphalt AH-90 decolorized asphalt and heat it to a fluid state at 100°C, add 5 parts of force-sensing material and 5 parts of reinforcing agent under stirring conditions (speed 100rpm), and stir for 20 minutes to obtain mechanochromic asphalt materials, stored for later use.

[0032] When mixing, heat the mesochromic asphalt material to 150°C, heat the stone material graded as SMA-13 ​​to 155°C, and then mix the asphalt and stone material; during construction, spread the mixed asphalt and stone material on the road surface On, the temperature is controlled at 130°C for compaction treatment.

Embodiment 3

[0034] Select 100 parts of heavy traffic road asphalt AH-90 decolorized asphalt and heat it to a fluid state at 100°C, add 1 part of force-sensing material and 1 part of reinforcing agent under stirring conditions (speed 100rpm), and stir for 20 minutes to obtain mechanochromic asphalt materials, stored for later use.

[0035] When mixing, heat the mesochromic asphalt material to 160°C, heat the stone material graded OGFC-13 to 160°C, and then mix the asphalt and stone material; during construction, spread the mixed asphalt and stone material on the road surface On, control the temperature at 140°C for compaction treatment.

[0036] In the above examples, the comparison between the mechanochromic asphalt material and AH-70 and AH-90 asphalt:

Abstract

The invention discloses a force-induced discoloring asphalt material for an asphalt pavement in a tunnel. The force-induced discoloring asphalt material is prepared from discoloring asphalt, a force-sensing material and a reinforcing agent. The force-induced discoloring asphalt material has the advantages that by adding the force-sensing material and the reinforcing agent into the discoloring asphalt, the road pavement is yellow under the condition of no automobile driving on the road pavement; the road pavement is blue under the condition of automobile driving on the road pavement; the road pavement can emit light for a long time; the problems of poor light emitting efficiency and short duration in the existing light-emitting asphalt road pavement in the tunnel.

Description

technical field [0001] The invention belongs to the field of asphalt pavement materials with special functions, and in particular relates to a mechanochromic asphalt material used for asphalt pavements in tunnels and a preparation method thereof. Background technique [0002] The road surface of the tunnel is in a closed environment, lack of sunlight, and poor brightness. It is easy to form a huge contrast with the bright environment outside the tunnel, causing the driver to experience "dark adaptation" and "light adaptation" visually when the vehicle enters and exits the tunnel, resulting in short-term visual barriers and affecting Driving safety. Although the lighting in the tunnel is enhanced, the effect is not good, and the consumption of a large amount of energy does not reduce the occurrence of traffic accidents. Especially for (extra) long tunnels, there is a great hidden danger to driving safety. Therefore, many researchers have turned their attention to the researc...
