Fayat’s green asphalt plant uses RAP

273 Marini-211 Ermont is introducing its innovative TRX100 asphalt plant, which utilises a patented low temperature technology that allows it to use feed material containing up to 100% recycled asphalt pavement (RAP). The plant has been developed in partnership with Eurovia’s Technical and Research Division in a bid to increase the use of RAP for road building.

And has been designed with a high level of mobility, allowing it to be set up and in production rapidly, close to road-building sites. The bulk of the RAP for the feed can be sourced from milling materials produced by the site, helping to reduce transport requirements as well as the site’s carbon footprint.

The patented TRX 100% technology, based on the drying of asphalt aggregates at low temperature, is said to reuse and preserve the binder in the asphalt. This is achieved through longer mix times, together with an innovative heating system. According to the firm, the TRX 100 is the most efficient mobile recycling solution on the market.

The plant forms part of Eurovia’s project to construct roads made entirely from recycled materials. The aim is to significantly reduce the use of raw materials and greenhouse gas and polluting emissions while delivering mechanical performance identical to that of new materials, sustainably and at competitive prices.  The project is supported by the French Environment and Energy Management Agency (ADEME). The project started in April 2017 and the programme covers study, design and prototyping phases and a demonstration plant, real on-site testing as well as a validation phase. Studies and tests on materials produced will be run in parallel to check their performance.

The demonstration will be on a road stretch with high traffic loads and will deliver road foundations with a recycling rate close to 100%

Once the economic model of the “100% recycled” solution has been validated, the plant is expected to be duplicated in France and abroad on major road maintenance sites, which are its primary targets. This infrastructure offers high volumes of material with features suitable for complete reuse in major maintenance operations.
