A very long story of recovery

Each road presented three basic technical elements (in image 1): a base ballast,

an "elastic" intermediate core and an outer covering. The ballast was a layer 30

to 60 cm deep called the statumen, formed by large flakes of hard stone and

eventually surmounted by another layer (rudus) of 25 or 30 cm made of smaller

stones and kept compact with lime and pozzolana. The intermediate nucleus

(nucleus) was a layer made of sand and crushed stone (or gravel or fragments of

earthenware and debris),
