| 摘要： | In 1995, ODOT sprayed the reinforced shotcrete slope stabilization project near Port Orford on US 101 with Permeon, rock coloring material also called desert varnish. The application colored the shotcrete to a weathered-looking dull brown, masking its gray-white concrete appearance. Some weathering in the last three years has changed the color. Water and mud running from the above cliff have added white and brown streaks. Also, wind and salt air erosion have faded some of the coloring. The test area is still darker than the control section which received no application. The value of the desert varnish appears to be marginal. If the three-year trend continues, the salt air and strong winds will discolor the entire treatment. |
