Roads served to link the most important military places in the new province of Britannia
Construction details

As straight as possible- using groma
Series of layers
1. Engineers called ‘agrimensores’ who marked the route
2. Cleared the path
3. Excavated and filled with stones or gravel to improve stability
4. Foundation called ‘statumen’ - layer of stones and gravel mixed with lime or cement to create a stable base (distribute worth of road and prevents water from seeping into the ground)
5. Pavement layers consisting of rudus (smaller stones/broken bricks mixed with mortar/lime), nucleus (concrete), and summa crusta (fitted stones or paving slabs)
6. Drainage through ditches, culverts and cambered surfaces
7. Sidewalks and curb stones for pedestrians
8. Marked by milestones and information given through signposts
