Small Scale Military Headquarters

Making my own custom 1:48 airfield road diorama in an acrylic display (old Duplo promo display), I now made an air background (from own sky-photo) + put some trees at the bottom and placed 1 jet in the sky for the effect.

Now designing an airfield road floor, which is kind of hard as I am searching for the correct asphalt lay-out with green lines and some grass. I first wanted to make it all with the trainhobby materials, but not sure now. Does anyone have some tips?

When finished it will display a 1:48 Hind and 1:48 Su-25

Will place some pics when the project has been finished.

Thanks for all the reactions. I bought the Noch 7085 (asphalt sticker) for making the airfield road. Now need to find a way to draw a yellow and white line on the airfield road.
