Development and Application of Ambient Temperature Dual Component Road Marking Coatings
In order to solve the problem of insufficient durability of existing road markings,the raw materials and formulas of two-component coatings were screened and optimized,and a room temperature two-component marking coating was prepared,based on an analysis of the research and application status of existing dual-component markings.The wear resistance,adhesion and other properties of the coating were evaluated,and the performance of the homemade coatings and conventional coating was compared and analyzed.The results show that:1)All the properties of the homemade coatings meet the specification requirements and are superior to conventional coatings;2)Practical engineering applications have shown that the developed two-component marking paint is suitable for repairing old markings on cement and asphalt pavements.After one year of repairing asphalt pavement markings,the reflection coefficients are all greater than 200 mcd·m-2·1x-1,and the paint adheres well to the old markings without aging or cracking.After repairing the old markings on cement concrete pavement,the average initial reflection coefficient is greater than 400 mcd·m-2·1x-1.After 5 months,the values of the reflection coefficient are all greater than 350 mcd·m-2·1x-1,indicating a significant improvement in the visual recognition performance of the old markings.This coating can be promoted and applied on projects of repairing old markings.
