2. Raised pavement marker - Wikipedia

   en.wikipedia.org/wiki/Raised_pavement_marker

   The marker is generally held in place using butyl pads, epoxy glue, or bitumen. [2] In areas with little snowfall, reflective raised pavement markers are applied directly on top of the road surface. The device's retroreflective surface enables the device to be clearly visible at long distances at night and in rainy weather.

3. Road surface marking - Wikipedia

   en.wikipedia.org/wiki/Road_surface_marking

   Epoxy consists of parts: a pigmented resin base and catalyst. The two parts are mixed in a specialized truck for epoxy marking application. The epoxy is then heated prior to spraying onto road surface. Retroreflective glass beads are applied using a separate bead gun behind the epoxy spray gun. Typically, epoxy markings last about four years. [13]

   A speed table (also called a bus-friendly hump, flat top hump, or raised pedestrian crossing) is designed as a long speed hump with a flat section in the middle. Speed tables are generally long enough for the entire wheelbase of a passenger car to rest on top. [ 25 ]

   Today, there are more than 25 million Botts' dots in use in California, [6] though they have started falling out of favor. In 2017, Caltrans announced that it would stop using Botts' dots as the sole indicator of lane division, due to cost and worker safety, and in order to make roadways more compatible with self-driving cars.

7. Resorcinol glue - Wikipedia

   en.wikipedia.org/wiki/Resorcinol_glue

   Until the invention of epoxy resin, resorcinol was one of the most common marine glues. Unlike epoxy, it does not have gap filling properties, requiring joints to be close fitting and clamped under pressure to achieve good results. The glue comes in two parts, a deep red syrup and a light brown powder, that are mixed to form a dark reddish ...
