This paper presents a water flow model through porous pavements. It links the hydraulic conductibility kD of the porous pavement with the geometrical characteristics of the road section and the rainfall intensity I. The theoretical model has been tested in laboratory using an original device. According to the experimental data, an useful chart for porous pavements design is also given. Data provided with this graph could improve porous pavements design (e.g. to assess the minimum thickness of an open-graded friction course needed to avoid surface runoff) usually based only on mechanical resistance determinations. Otherwise, to fit best flow conditions the relation i2>4I/k must always be verified

Abstract
This paper presents a water flow model through porous pavements.

The theoretical model has been tested in laboratory using an original device. According to the experimental data, an useful chart for porous pavements design is also given. Data provided with this graph could improve porous pavements design (e.g. to assess the minimum thickness of an open-graded friction course needed to avoid surface runoff) usually based only on mechanical resistance determinations. Otherwise, to fit best flow conditions the relation i2>4I/k must always be verifiedI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
