The roadway at a road-rail crossing comprises rows of extruded rubber strips. The strips have a tongue-and-groove type of edge connection, which constrain the strips such that if one strip bounces the adjacent strips bounce too. Locking-strips fit between primary-strips, and have latches, which snap into place upon the locking-strips being driven downwards, from above.
