| Summary: | 碩士 === 國立高雄應用科技大學 === 模具系碩士在職專班 === 105 === At present, hot-melt road markings is used most in Taiwan. According to Traffic Engineering Code of the Ministry of Transportation and Communications, the general road marking anti-skid coefficient needs to be higher than 45 BPN (British pendulum number), with the material hot melt resin, and add glass beads, to achieve reflective effect. Although it can increase the visibility at night, it also cause scooter slipping when it is raining.
This study is aimed at changing the existing pattern of road marking, design with drainage function and increase the anti-skid coefficient line, reduce the scooter rider slipping fall. This study designed three groups of different hot-melt line: crossed lines (A), cross Slash (B), horizontal line (C) (perpendicular to the road direction) compared with the current road markings wear resistance and sliding resistance coefficient, by the design of 3D printing embossing mark to produce lines, using # 100 abrasive wear compared to wear-resistant times are 5600Cycle, 8400Cycle, 10800Cycle, 12000Cycle, by ultrasonic sensor scanning the received reflection signal size data. Through the MATLAB program, the data are converted into matrix contact area images, and the Powerimage analysis software is used to analyze the different contrast coefficients, and the contrast coefficient is analyzed from 10% to 100%.
The area values and graphs of the contact area are calculated, and the area between the wear and the wear of the different grains is different. And then by the electronic push and pull gauge load 200g measuring surface antiskid coefficient is worth to cross line 0.56kgf, cross slash 0.53kgf, horizontal lines 0.55kgf and the current road marking 0.42KGF. The

research with the British pendulum anti-slide test, the abrasion resistance of the road marking is up to 12000Cycle, but the slip resistance of the wet test pendulum is only BPN, and the antiskid coefficient is not enough to the other crossed lines 56BPN, the cross slash 51 BPN, the horizontal 54 BPN. It can be learned that increasing the markings on the surface of the line can improve anti-skid but relatively reduce the number of wear. Hopefully, the result of the research can provide traffic authority concludes examination complainant, can be used as the basis for the development of new standards for road marking, effectively enhance the safety of road marking.
