Abstract:
The objectives of this study were to investigate viable alternatives to the currently approved snowplowable raised pavement marker and alternative methods and equipment used to snowplow roadways. The study included evaluating any potential durable and effective pavement marker that is not disruptive to snowplowing operations and alternative snowplowing procedures and equipment that do not damage pavement delineation and pavements. Implementation possibilities resulting from the research project include a recessed snowplowable marker and improved/alternative snowplowing procedures and equipment. The alternative snowplowable markers included in the evaluation were the current steel casting marker and a recessed marker. The evaluations confirmed past research that the steel casting marker can be used on new pavement if the casting and lenses are properly installed and maintained. Also, the pavement surrounding the casting must be maintained. The limited experience with the recessed marker has shown it to be an effective alternative to the current steel casting marker. The durability and effectiveness of the recessed marker should continue to be monitored. There are alternatives to the current snowplowing procedure of using steel blades with full weight on the pavement. Several types of blades were evaluated with varying levels of success. Evaluation of alternative snowplowing procedures should continue using information found from these initial trial tests. Contractors should be allowed the flexibility to use alternatives to steel blades with their performance monitored.
