Asphalt concrete HR

  1. 1. Asphalt concrete HR AN EVIDENT RESOURCE From a unique mix design or different ones, from Today, Eurovia proposes performing and pavement dismantling or a plant surplus, reclaimed responsible solutions to satisfy the needs of its asphalt pavement can be recycled in asphalt clients that are quality, savings and respect of concretes. environment. For example, a formula containing With the sustainable development followed by Eurovia, the protection of natural materials is a major point of the company’s concerns, also favored by abundance of resources of RAP. Therefore the techniques using recycled materials have developed considerably. 30% of reclaimed asphalt pavement with a binder content of 4.5% allows to save about 30% of natural aggregates but also 25% of new bitumen.
  2. 2. P ReCISE Studies a targeted PRODUCTION The identification methodology of RAP storages is imposed by the prevailing legislation (NF EN 13108-8). So every characterization of a batch leads to a technical leaflet for reclaimed asphalt pavement. Tests and controls allow to find the right use of these materials meant for recycling. Independent of the quality itself of the reclaimed asphalt pavement, the recycling rate is highly depending on the type of the mixing plant and the mode of reincorporation in this plant. In addition, regarding the constant concern to optimize the resort to RAP, Eurovia uses a thesis carried out by its Research Center and which aimed at quantifying remobilization of the binder coming from RAP when producing a new formula. With this knowledge, the company proposes to produce the most appropriate recycling rate according to available resources and type of asphalt concrete. Every conventional asphalt concrete but also most of the products and processes of the Eurovia range can use reclaimed asphalt pavement. The warm mixes of the Tempera® range are not an exception and the company does not hesitate to propose the combination RAP / warm mixes. Every year, Eurovia valorizes more than 2 million tons of RAP corresponding to an average recycling rate of 13% in its own asphalt plants. That is why, from now on, when the recycling rate is over 30% in an asphalt concrete formula, the letter HR will be added to the product’s name: for example, a Renfovia® with 40% of RAP becomes a Renfovia® HR. k ey figures More than 2 million tons of RAP recycled every year Recycling rate up to 70% Economy of bitumen supply over 25% Tempera® is a registered trademark. Renfovia® is a registered trademark.

However, with the numerous settings up of the company on the territory, there is the possibility to produce asphalt concretes at high recycling rate for everyone: RAP can be introduced up to 70% on certain industrial facilities.
