Description
When raining in the dark you CANNOT SEE ANY LANE MARKERS. Why is it the north east states and CO don't have issues with striping on the roads but Utah does? THIS IS UNSAFE and Utah says they are studding the problem. How long does it take you fools? Other states have snow and don't have this issue like we do.

In order to make our striping reflective we use round glass beads embedded in paint and other binders as shown below. The light is reflected back to the driver's eyes.
The visibility of the reflectivity is reduced in the winter by the accumulation of salt and dirt on the road. We rely on the spring rains to wash off the salt and dirt. It is also reduced, of course, by rain and snow.
The durability of our striping is impacted by plowing and traffic. In the past few years we have started recessing more of our striping below the road surface to help it last longer.
Striping is weather dependent. It can only be applied when the temperature is 50 deg. F minimum and when the road surface is dry. In the urban areas, it is also traffic dependent. It is done during off-peak hours, usually at night, when traffic volumes are at a minimum.
Utah is divided into 6 striping districts. Each district has a full-time crew that stripes continuously during the warm months. Each district's goal is to paint every road every year. They also have the ability to hire a contractor to help out with their work when they can't get to all roads because of weather or equipment malfunctions.
Striping is also installed by contractors on our road reconstruction projects.
We are working on a better solution to improving the visibility of our lines in wet weather. We have tried several approaches. One test that we're still evaluating is by mixing special wet reflective beads that shine under water with our regular beads, as shown below, and recessing them below the road surface.

Another test we’re working on is the recessed plowable marker that Arizona uses in Flagstaff and other plowed locations, as shown in the picture below.
These have proven to be successful in improving wet night visibility for Arizona DOT. We have put these down as a field test in 3 locations to evaluate them. Initial results are promising. We still have some pavement durability questions to answer but we are working on it. We will implement them statewide if they are successful.
We are also actively looking at installing other recessed marker designs that have been working in other states.

215 still has not been re-striped and we still cannot see the lane markers in even a light rain.
