ASTM RR:D04-1026 PDF Download

The ASTM RR:D04-1026 standard specifies the requirements for pavement markers that are used for enhancing road visibility, especially during nighttime or adverse weather conditions. These markers are designed to be nonplowable, meaning they can withstand snowplow operations without being damaged or displaced.

The standard covers various aspects of the pavement markers, including the materials used, performance requirements, installation methods, and maintenance. It specifies the size, shape, and color of the markers, as well as their retroreflective and durability properties. The markers should be able to provide adequate retroreflection to ensure visibility from a distance and under varying lighting conditions.

The ASTM RR:D04-1026 standard also outlines the testing procedures and performance requirements for the markers. This includes tests for adhesion, retroreflectivity, impact resistance, and environmental stability. It provides guidelines for conducting these tests in a laboratory setting to ensure consistent and reliable results.
