Obviously I did not know this area of New York. In fact, I did not know that the level was based on a real zone. My fault.
The original texture, besides having low resolution, had a very small pattern to the cracks. And the cracks are in 3 bands stretched across the texture. I've been seeing pictures of FDR and there aren't so many cracks. I created a new texture (double resolution) without no cracks, and added bump detail layer. Then I'm doing a new decal cracks. I do not know if I will make a new road material to stretch over the asphalt or leave it as seamless decal to be placed randomly. Here I post some of the steps (diffuse, bump mapping, parallax, transparency). Both are "work in progress". Maybe a little less blue and a touch of red in the asphalt diffuse.
Thank you all for the opinions.
