Cheers Serch, I'm glad you like it!
I'm away from my computer right now so can't show screengrabs, but will put something together when the project is a bit further along. I'll try describe as best I can now. It's all quite simple geometry, just 10m sections of road with just a slight bulge in the centre, then instanced and a single noise map applied over all instances to add some variation.
Most of the work is in the materials here. Multiple 10k px long textures with all the markings and varying levels of dirt all blended together with noise maps. I still need to add more variation and create some damaged sections, as the road is broken up into 10m sections I have a lot of control over where the damaged parts will go. On the edges I will also be scattering some tiny debris, where the old asphalt it crumbling a bit as well as dirt, dust and litter being blown off the road to the sides. This will all be geometry.
Post work was done in Photoshop using Arion FX and Camera Raw. I added some chromatic aberration and glare in Arion FX and did some tone mapping. I quite like using Camera Raw because I can save a variety of adjustments easily as a preset. There I adjusted the exposure and curves, added more contrast using clarity. I had initially planned to have this in colour, but as an experiment I converted to B&W and really liked it so kept that!
DOF is rendered. I think it's roughly a 100mm lens, F stop of 12 if I remember correctly, so DOF isn't over the top.
