Battering ram questions

[Oddity]

1. Does a battering ram move faster on paved ground, like a cart? (if so, does this mean I can move it farther before it breaks, or will it be the same number of tiles regardless?)

2. Does the quality of the materials I use to make it have any effect on the distance it can travel before breaking?
