What are the Different Types of Reflective Barricade Tape?

There are three types of barricade tape commonly used: Engineer Grade (ASTM D4956 Type 1), Super Engineer Grade (Type 2), and High-Intensity Grade (Type 3). Each type of tape serves a specific purpose based on its brightness and visibility.

  1. Type 1 Reflective Barricade Tape: Type 1 barricade tape, also known as Engineer Grade tape, is designed to provide moderate visibility. It meets the standards set by ASTM D4956 Type 1. This tape is commonly used in work zones where traffic speeds are lower or where work is being conducted at a distance from traffic. It offers adequate reflectivity for such situations.
  2. Type 2 Reflective Barricade Tape: Type 2 barricade tape, also referred to as Super Engineer Grade tape, offers enhanced visibility compared to Type 1. It meets the standards of ASTM D4956 Type 2. This tape is approximately twice as bright as Type 1 tape, making it suitable for work zones where traffic speeds are higher or where work is being performed closer to traffic. The increased brightness helps ensure that drivers can easily see and navigate around the work area.
  3. Type 3 Reflective Barricade Tape: Type 3 barricade tape, known as High-Intensity Grade tape, provides even greater visibility than Type 2. It meets the standards set by ASTM D4956 Type 3. This tape is approximately four times as bright as Type 1 tape, making it highly effective in alerting drivers to the presence of a work zone. It is recommended for work zones with high-speed traffic or areas where maximum visibility is crucial.
  4. Type 4 Reflective Barricade Tape: Type 4 barricade tape, also called High Intensity Prismatic Grade tape, offers enhanced brightness and visibility compared to Type 3. It meets the standards of ASTM D4956 Type 4. This tape is designed with a prismatic construction that maximizes its reflective properties. It provides approximately 30% more brightness than Type 3 tape, making it an excellent choice for applications where high visibility is essential.

The choice of barricade tape type depends on factors such as traffic speed and proximity to the work area. It is important to consult the Manual on Uniform Traffic Control Devices (MUTCD) guide for specific regulations and recommendations regarding the appropriate type of tape to use in different situations.
