KEyfIgURES

The use of cold asphaltic concrete in pavement surface courses calls for specific emulsion

formulations and for suitable production and laying processes.

Eurovia has developed environmentally friendly pavement maintenance techniques based on

cold materials. This expertise has given rise to an exclusive, highly effective process: Ecolvia.

ECOLVIA COLD ASPHALTIC CONCRETE

ATD of 1 to 1.5 mmat young age

40 to 80 mm thickness

ACROSS THE BOARD EffICIENCy

Ecolvia, a cold asphaltic concrete for surface course maintenance, is produced cost-effectively in a cold mixing plant. It generates no dust or fumes and is particularly environmentally friendly.

Eurovia has special, very compact and mobile mixing plants suitable for all types of project.

The excellent workability of Ecolvia offers substantial flexibility in use and the product can be laid by paver, grader or manually. The mix is compacted with a smooth roller or a PTR.

The pavement can be re-trafficked after elimination of the emulsion breaking water and curing of the mix. The time required depends on weather conditions and traffic level.

OUTSTANDINgVERSATILITy

Ecolvia is used to maintain roads with moderate traffic requiring restoration of skid resistance characteristics.

It is applied as a surface course in a layer generally ranging between 40 and 80 mm.

Ecolvia is equally effective when used for reprofiling, smoothing, truing and levelling and edge maintenance.

PAVEmENTRENEWAL

Ecolvia is made up of a dense-graded skeleton - generally 0/10 mm but sometimes 0/6 or 0/14 - coated with a pure bitumen emulsion with an adapted formulation.

> Aggregates are derived from solid rock or alluvial deposits depending on traffic and the conditions in which the mix is used. They are selected in accordance with the EN 13043 "Aggregates for hydrocarbon mixes" standard.

> The binder is a cationic bitumen emulsion that can be produced in any of Eurovia’s binder plants.

The characteristics of the components of Ecolvia as well as the formulation of the mix ensure that the material is fully coated. Voids content ranges from 6 to 12% depending on the formulation selected.

The mix offers excellent water resistance, eliminating the risk of binder stripping. The good cohesion of the material ensures that aggregates are not stripped or plated.

Suitable formulation ensures compliance with the requirements of the P 98-139 "Surface courses: cold asphaltic concretes" standard.
