| Long-term experience in the United Kingdom is very limited, but based on
trials carried out in 1984, it was concluded (Daines, 1992) that ; Based on
experience to date, 20 §® porous Asphalt using 100pen unmodified bitumen with 2%
of hydrated lime as filler and a binder content of 3.7% will last in excess
7year under 4000 cvd with effective spray reduction |

| Porous Asphalts with higher binder contents (which can be achieved with
certain modifiers) will probably last significantly longer, but they will have
reduced hydraulic conductivities |

enough to make it a viable surfacing material, with a service life comparable
with that of dense asphalts |
