The present invention is directed to track control mats (10). The track control mats (10) contain two distinct, superimposed, layers of polymeric material. The first layer (12), or base layer, is formed from a first polymeric material, which provides a first degree of flexibility to the mat (10). The second layer (11), or cap layer, is formed from a second polymeric material, which may contain a colorant. The colorant enables the layers to b e visually distinguishable from one another. |
