BULK INSERT and APPLICATION ROLE

I want to add bulkadmin permission to my applicatio role. Is it a
posible.
My windows account havo only public permission on database.

I'm using application role

EXEC sp_approlepassword 'MyRole', 'password';

Therefore I want to BULK some data with BULK INSERT command.
Error is:

The current user is not the database or object owner of table
'tablename'. Cannot perform SET operation.

Thanks in advance.

In previous message I made a error. I am setting a aplication role by
command sp_setapprole instead sp_approlepassword
