<p>The Highways Agency maintains databases containing indicative “end of life” dates
for different types of asset. For carriageway assets, these dates may change for reasons
such as the level of use, severe weather and damage from incidents. Concrete surfaces
such as those on the M20 between junctions 8 and 9 have an indicative design life
of approximately 40 years. This section was laid in 1991; therefore the indicative
end of life is around 2031. However, as the current need for retexturing some short
stretches of the M20 between junction 9 and 8 indicates, it may be that end of life
will arrive before 2031. The Highways Agency will continue to monitor the M20 and
as appropriate will bring forward partial or complete resurfacing schemes using modern
quieter surfacing.</p><p> </p><p> </p><p> </p>
