Provided you put in the right amount of work in a fitness programme there is no reason why trotting on the roads will hurt a sound horse, its what the horses used to do in the days before vehicles were used to transport everything from place to place, they would be working day in day out, carriage horses frequently trotted everywhere.
We had a pony that worked on roads all his life with plenty of trotting, he showjumped, competed working hunter & became a hunter for real when he was in his 20's, he died in his late 30's and never had a lump or bump on his legs or a days unsoundness
