REFLEX

REFLEX är ett EU-projekt där syftet har varit att utveckla en metodik som kan förstärka en beläggnings hållbarhet genom att använda stålnät. Detta förfaringssätt föväntas kunna ge tunnare men samtidigt även starkare konstruktioner, som därmed är kostnadseffektiva – lång livsländ, samt mindre åtgång av naturresurer.

Executive summary
In many countries premature break down of asphalt roads is an accelerating
problem. The origin is usually increasing traffic volume and axle loads, and
the use of super single tires. The main objective of the REFLEX project is to
develop a new methodology of road construction and rehabilition with the use
of steelreinforcement fabrics in order to make road structures more cost
effective by improving the life time. The method is presume to give thinner road
structures and/or longer life cycles, which will lead to a reduction in the use of
natural resources. Further, reduction of the need for maintenance, reduction of
congestion, redaction of accidents, improvement of safety of road traffic can
be expected.

Industrial objectives and strategic aspects
Many billions of EUROs are spent on road construction and maintenace each
year, and road transport is the primary method of mobility for European people
and goods. Transport constitutes about 10% of the Gross National Product of
the European Union and more than 80% of the total transport of the people and
goods is provided by the road infrastructure. Wellmaintained roads and highways
are therefore essential for the economic and social development of Europe.
Inadequate pavement maintenance and rehabilitation can also have serious
consequences for the safety and comfort of the road users. There is continuing
requirement for more efficient methods of pavement maintenance and rehabilitation
aimed at producing solutions, which are less disruptive to the environment and to
the road user, as well as being more economic and of higher quality than those
presently in use.
