US President Donald Trump's pledge to fix America's ailing roads, bridges and airports may get an unlikely boost from retirement savers some 10,000 miles away in Australia.

In face-to-face talks at the White House this week, Prime Minister Malcolm Turnbull will propose using a chunk of Australia's $2.53 trillion superannuation pool to help unlock funding for Trump's infrastructure push.

He's being joined on the trip by local money managers who help control the world's fourth-largest pot of retirement savings.

"There's a very bold ambition to drive US infrastructure and Australia should be front and centre in terms of project design, build, financing and management," Trade Minister Steven Ciobo said in an interview ahead of the visit.
