Yellow asphalt in the Maastunnel in Rotterdam
Municipality of Rotterdam
When the tunnel was finished in 1942, there were yellow clinkers in the road surface until it was so damaged in 1965 that these were replaced by grey asphalt. Now, more than 50 years later, the tunnel is restored the tunnel to its former glory. Using Reflexing white crushed stone and a yellow pigment, a reflective road surface is created to enhance safety and durability.
