Embodiment 1

[0045] Small-radius curved road section refers to the road section whose curve radius is smaller than the general minimum radius specified in the road survey and design. In this case, there are certain safety hazards for vehicles turning and driving, and warning markings need to be arranged.

[0046] Warning markings on small-radius curved road sections: the markings are composed of the upper moisture-sensitive discoloration layer 1, the middle warning pattern layer 2 and the lower prefabricated marking layer 3;

[0047] Described prefabricated marking layer 3 adopts commercially available prefabricated marking; Draw warning pattern on prefabricated marking layer 3, form warning pattern layer 2 after completely drying; Mineral oil and antioxidant are mixed evenly according to the mass ratio of 25:1:1:2 to obtain the moisture-sensitive discoloration material; then the moisture-sensitive discoloration material and water are mixed uniformly according to the mass ratio of 25:1 at r...

Embodiment 2

[0068] According to different functions, the three-dimensional intersection ramp road section can be divided into a hub interchange and a general interchange. The focus of the setting of traffic markings at inter-level intersections is to deal with the problems of interweaving and conflicts that are likely to occur during the traffic transition process between the main line and the ramp, and between ramps. Through the setting of traffic markings, the driver of the vehicle can predict and perceive the road ahead. Conditions and traffic conditions, take effective measures in time to prevent traffic accidents. When driving out of the interchange from the ramp, the driver often needs to slow down to a safe speed according to regulations due to changes in road conditions and changes in driving direction. From the perspective of driving psychology, when the driver decelerates from a higher speed, there will often be deviations in the grasp of the speed. Inadequate deceleration, tha...

Abstract

The invention discloses a traffic alarm mark line based on the humidity sensing color changing technology and a construction method thereof. The mark line is composed of a humidity sensing color changing layer on the upper layer, an alarm pattern layer on the middle layer and a prefabricated mark line layer on the lower layer; the prefabricated mark line layer adopts one-line prefabricated mark lines; alarm patterns are drawn on the prefabricated mark line layer, and after drying is performed, the alarm pattern layer is formed; at the room temperature, a humidity sensing color changing coating, carbonate powder, mineral oil and antioxidant are uniformly mixed according to the mass ratio being 25:1:1:2, and the humidity sensing color changing material is obtained; after the humidity sensing color changing material and water are uniformly mixed under the room temperature according to the mass ratio being 25:1, the mixture coats the alarm pattern layer through a screen printing technology, after drying is performed, the humidity sensing color changing layer is formed, and alarm mark lines are obtained. When the road is dry, the mark lines are white, and the stimulation degree to the driver is appropriate; when the road is slippery, the mark lines are changed into the striking alarm color, the 3D visual effect is shown, and the early warning effect on the driver is achieved.

Description

technical field [0001] The invention relates to the field of road traffic, in particular to a traffic warning marking based on a moisture-sensitive color changing technology and a construction method thereof. Background technique [0002] When the road is wet and slippery, there are hidden safety hazards that the driver cannot predict, and the braking performance of the vehicle is significantly reduced, requiring the driver to take deceleration measures in advance. When approaching a dangerous location, if the driving speed is too high, situations such as overturning and sideslip may occur, causing the vehicle to become unstable. Especially in some special road sections such as small-radius curved road sections, three-dimensional intersection ramps, long downhill road sections, etc., there will be greater safety hazards, which will cause a series of traffic accidents. The current road deceleration facilities mainly include: hard deceleration ridges, oscillating deceleration...
