Is it possible that you have marked the screen space refraction box in the material of the road? in my knowledge, the volumes, SSReflection and SSRefraction (EDIT:and SSS) cant interact with each other.
sorry for my English.
Pragmatically speaking, 6eye, please don’t just “show us a picture” and ask, “can anyone help?” We need to know: "what is the problem?" We’re probably not that good at guessing.
Also, it helps tremendously when you can attach a very small
.blend file which specifically illustrates the problem.
