Introduction
One phase of this work has been the study of an efficient mode of treatment of
the carriageway drainage materials, aiming at improving their environment
quality. Efficient cleaning up methods exists for chemical treatment (heavy metals,
hydrocarbons) as well as for giving a texture adapted to material reuse (screening,
washing). These often complex methods are costly, which may form an obstacle for
an effective reuse of the cleaning out solid waste.
Experimental Method
Classification of Drainage Solid Waste
Road drainage sediment classification according to their environmental characteristics
has been carried out, distinguishing two main sediment categories.

Sediment from ditches
Studied ditches are solely rassy ditches and curved channels. Concrete curved
channel and ditches generate sediment similarly to carriageway dust (compound
