I am not very sure what you are looking for. Are you looking for educationanl materials from universities ? Why not try the websites of the universities ?
Are you looking for educational materials, such as GEOCAL in England ? There used to be some sites where you can access some of the materials related to civil/geotechnical engrg, such as designing roads, dams, etc.
I don't know if they still have them. There is also discussion forum in Geocal, on various subject in Civil Engineering. You may check at
