Eurovia has developed a surface course of choice for pavement maintenance, Fibrovia®, which
has many advantages - workability, flexibility and strength.

Fibrovia® is a surface course of choice for semirigid and flexible pavement maintenance. In
flexible pavements, it accommodates higher
deflection values than those typically accepted by
conventional very thin asphaltic overlays. Fibrovia®
is appreciated as a wearing course for city streets,
where its workability allows uniform laying, both
mechanised (paver) and manual.
Fibrovia® is a dense-graded 0/10 thin or very thin
asphaltic overlay with high binder content and
organic fibre reinforcement.
It is used as a surface course in average thicknesses
of 20 to 40 millimetres. An emulsion tack coat with
approximately 400 g/m2 residual bitumen is always
laid in conjunction with Fibrovia® and helps obtain
a waterproof surface. In cases of heavy loadings,
modified bitumen is used in this tack coat.
IGH ORGANIC FIBRE
The formulation of Fibrovia® combines a densegraded but very coarse (more than 70% elements
greater than 2 mm) mineral skeleton with high binder
content. The use of short fibres with high specific
surface area makes it possible to increase the binder
content by 1% compared to a conventional formula.
The fibres used are organic. They are either
packaged in meltable plastic bags or coated with
bitumen and supplied as pellets in bulk (big bags).
The choice of packaging depends on the type of
coating plant used.
The Fibrovia® binder is usually a pure 50/70 or
35/50 bitumen, depending on the geographic area.
Fibrovia® production does not require storage of a

The formulation of Fibrovia® produces a strong,
flexible mix, which has good resistance to permanent
deformation and highly satisfactory surface
characteristics. The relatively high binder content
gives the mix very good workability, facilitating the
