A pit type weighbridge is mounted in a pit. It takes more work to install. The weighing surface is level with the road. A pitless type weighbridge is mounted on the surface. The weighing surface is mounted with a ramp leading up a short distance.
the road has a hard surface so that it can be flat and easy to drive on
because the rough surface is wet and a road is not :)
Surface types can affect the force of friction because as the surface gets rough and rougher it has more friction and smooth surface has less friction. if we compare the affect of friction force on a ice and road. Road is much more rough than the ice chunk and if we slide a ice hockey puck on each of the surfaces, we get that smoother surfaces has less friction.
