Firstly bear in mind you probably wouldn't have anything as hazardous as a fence anywhere near a taxiway so I would leave the fence for something else.
I once made a very similar base for a vintage motorcycle and the gravel was made from fine sand.
Use any sort of sand or gravel from the garden and apply a coat of contact adhesive to the base, sprinkle the dried gravel over it and pat it into the glue. When it has dried shake the excess of and add a bit of interest with some fine washes making sure that you do not hide the individual grain colours.
Normal garden soil if dried and seived will probably do the job.
Taxiways would normally be well looked after to prevent anything being kicked up by the prop wash so I would concentrate on some nice textures in the gravel and the grass and let the model do the talking. |
