Tank Foundation Question
Tank Foundation Question
(OP)
Good Evening everyone
i have a technical question about the foundation.
Where i'm working the client is using a kind of bitumen emulsion on the sand as final layer. In the civil drawing i read "50 asphaltic sand" as final layer. From my point of view the procedure of the client is not correct infact the result was a foundation with a coloured black sand but soft so i think that they have mistaken the proceudure. As mechanical contractor, according to Api 650, we must check only the concrete ring level and the internal slop and not the quality of the material of the foundation but i'm worried that they are doing something not good.
Can someone give me some information how to prepare an asphaltic sand and its method of application?
Because they are simply pouring the liquid emulsion on the sand of the foundation. I'm thinking that the asphaltic sand is as a mix of bitumen-sand according to appropriate percentage and applied simultaneously with a compactor.
I'm waiting for your response.
thank you very much
regards
Tanko
