key FiguRes

The appearance and colour of surfacings used for the various types of traffic – public transport,

automobile, bicycle and pedestrian - highlight and differentiate the areas set aside for their respective

users. In addition to being decorative, these surfacings therefore play a crucial safety role.

Eurovia has devised a way to use innovative materials in asphalt mixes to create a whole new range of

attractive and unusual surfaces: Agrevia®.

Agrevia® is a surfacing process that uses a hot asphaltic concrete and applies a special mechanical surface treatment to it to make the most of the aesthetic qualities of its aggregates.

The origin, colour, shape and grading of the aggregates and the type of mix are selected according to the use to which the surfacing is to be put and the preference of the customer.

Aggregates occur naturally in a wide range of colours ranging from black to white, pink and green. Eurovia uses this variety to give durable, informative and aesthetic colour to the road and its immediate surroundings.

Agrevia® can thus be used to create surfaces of diverse appearance, texture and colour.

The thickness applied is determined by the aggregate formulation and the loadings to which the pavement will be subjected.

aesthetic and demaRcation PeRFoRmance

Agrevia® combines a natural appearance derived from its constituent materials with the recognised qualities of asphalt mixes. It is flexible and joint-free for driving comfort and safety.

Agrevia® can be used to enhance the differentiation and demarcation of road uses to improve the safety of a wide variety of structures such as:

> sidewalks,> bicycle paths,> dedicated lanes,> shoulders,> emergency stopping lanes, > roundabouts,> pedestrian crosswalks,> directional islands.

Agrevia® can be specially formulated to give it a natural appearance, making it suitable for use in gardens and parks and in the vicinity of landmarks and historic sites. Agrevia® formulated with white or light-coloured aggregates is highly appreciated in special applications such as tunnels and underpasses, where it reduces the need for lighting and improves visibility and thereby safety.

The properties of Agrevia® , unlike those of film-based colouring processes, are not altered by traffic and have outstanding durability.

customised eFFectiveness

Aggregates Aggregates are selected according to the usual criteria pertaining to intrinsic characteristics and use (French XP P 18-545 standard) and also above all according to their colour and grading.

Materials of different origins and different colours are often mixed to give the surfacing an attractive marbled appearance. Sand and gravel can be used in the formulation to achieve a special surface appearance in pedestrian applications, as in the Antikvia® mix initially developed by Eurovia in Germany.

Binder The Agrevia® binder is generally a pure bitumen of grade 50/70 or lower.

Formulation The Agrevia® grading curve can be either dense or gap graded. The most widely used gradings are 0/10 and 0/14 mm but 0/16 and even 0/20 gradings are occasionally employed (Antikvia®).

If the surfacing may be subject to severe mechanical loadings – channelled traffic, heavy equipment parking, shear stress, etc. – a percolated mix may be used. The surfacing then offers the exceptional performance of Salviacim® industrial surfacing.

simPLe aPPLication

Agrevia® is laid by means of the usual mechanical or manual methods used to apply bituminous mixes.

Mechanical treatment is applied to the mix surface prior to trafficking in order to uniformly bring out the nature and original colour of the aggregates used. This operation is also applied, as appropriate, to improve the macrotexture or microtexture of the surfacing and thus enhance skid resistance and safety.

The operation is performed mechanically by grit-blasting, hydrostripping or sanding. Given the nature of the surface treated and the objective of the treatment, this operation must be carried out by highly specialised crews using special equipment.
