My local club is thinking in rebuilding a small track wich is used both for 1/10 and micro cars.
Itīs outdors and the asphalt is very bumpy because of roots from trees.
We were thinking in using concrete over the existing asphalt, but we are afraid that wont give enough traction.
A civil engineer sugested using concrete with small rocks (i want to say 'large sand' but dont know the word in english) and a sort of adesive compound.
Anybody as diferent sugestions? I noticed some tracks in USA seem to be from concrete, but i dont know whats the construction method used.
Any help most apreciated
