The government-owned company had been testing different speeds since September 2016 and found that drivers' heart rates were lower when driving at faster speeds of 55mph and 60pmh through roadworks.
The new speed limits could come into effect in some parts of the country this year.
Jim O'Sullivan, the chief executive of Highways England, told the Times that the 60mph limit was "something that we want to introduce to as many roadworks as possible".
He added: "The volume of roadworks that the network and our users can cope with is probably reaching its peak. If we're going to have this volume of roadworks, we need to have some serious thought about how we improve the customer experience."
But unions have warned that it would put motorway workers at risk.
Trade union Unite, which represents road workers in Britain, said they "work in already very dangerous conditions".
"Already motorists frequently drive into coned-off areas. At increased speeds, it will make such potentially lethal accidents even more common."
