Hello community

I have fixed my old problem but now i have to fix a new problem it contains the raod tool.
I made a road-path and i gave the road a texture. the problem: the texture of the road
disappears when i look at the road from some positions. the ground texture is visable through
the road. i don´t know how to fix this problem so i need your help please.
I ´ve added a picture so you can see the problem very well.
