It is known that the oil is not an inexhaustible resource and therefore the price
increasing. Bitumen is a petroleum product and this is the reason for using foamed
bitumen instead of pure bitumen when it needs a binder for pavement composite
materials. Technology with foamed bitumen mix consists of mixing aggregates at
ambient temperature, filler, possibly hydraulic binders and spraying hot bitumen as
foam. Among the foamed bitumen using in pavement construction and maintenance, the
pavement recycling using foamed bitumen technology occupies an important place.
This paper presents a case study on flexible pavements containing a base layer made of
foamed bitumen mixture resulted from "in situ" recycling of existing asphalt layers.
Will be presented comparatively the results obtained on original pavement, damaged
pavement and reinforced pavement, results to highlight the benefits of reuse and
conservation of non-renewable natural resources and environment preservation.

Keywords: recycling, foamed bitumen mix, half-warm-mix technology, damaged
pavement, reinforced pavement
