Legge driveway med asfalt eller vei grus

My driveway is 250m long and a max gradient 11 degrees. The foundation is rock but over the past years and snow clearing it is now in need of repair. It is max 3-4 m wide. i think vei grus compacted is a likely best option, asfalt quote i had in the past was over 250 000 nok, more than i can afford. i welcome quotes and options. Snakke norsk, men er vansklig med technisk sprak.
