Width expandable modular erosion control tile system and roadway boundary marker

Abstract

A width expandable modular erosion control tile system includes a plurality of open liner tiles and a plurality of expandable liner tiles. Either a female curved surface or a male curved surface is formed on opposing sides of each open liner tile. The male curved surface pivots relative to the female curved surface, upon contact. The male and female curved surfaces allow separate liner tiles to be retained relative to each other at different angles to conform to the shape of a ditch. A roadway boundary marker includes a plurality of interlocking segments. A male interlocking surface is formed on one end of the interlocking segment and a female interlocking surface is formed on the other end of the interlocking segment. A plurality of ridges are preferably formed on a top of the interlocking segment. A reflective material is mixed into the interlocking segment.
