Abstract

Bad lighting effect can be caused by bad pollution resistance of highway tunnel sidewall coating materials. Therefore, a kind of nanosilanion hydrophobic coating material is proposed, and its pollution resistance effect is examined and summarized from the aspects of principle analysis, test, and engineering application. The test results based on the pollution resistance principle show that the coating has the best pollution resistance effect when the content of nanosilica is 5% and the modifier content is 3%, while the coating smoothness reaches the highest when the coating color is white. The engineering application of this coating material in the Yakou tunnel of the ShanghaiChongqing highway show that: (1) The reflection coefficients of the coating in different periods are generally maintained above 0.7, and the reflection coefficient decreases by approximately 3% after operation and cleaning, but the pollution resistance and lighting performance are still good. (2) Based on the comparative analysis of tunnel lighting parameters, MTPA, and sidewall cleaning cost before and after coating, it is verified that the application of the coating material can improve lighting safety and comfort, reduce operation and maintenance costs by 80%.

Key words： highway tunnel; sidewall coating; dirt resistance; lighting; reflection coefficient
