The benefits of Gipave® also confirmed by research from the University of Nottingham

Thanks to the cooperation between Amey, Kent County Council andNottingham University (Transport Engineering Centre), specific research was carried out aimed at investigating the properties of Gipave and the possibilities of use for construction and maintenance works in Kent. The research is part of the (ADEPT) SMART Places Live Labs program and is based on experimentation which was conducted in 2020 in Dartford in Kent (UK).

Gipave, developed by Iterchimica thanks to a research project developed in collaboration with Directa Plus, G.Eco and the University of Milan-Bicocca, is a polymeric supermodifier containing graphene and a specific type of recycled plastic that does not it falls within the standard recycling chain but is destined for waste-to-energy plants. To date, Gipave has been widely used both in Italy and abroad on different types of flooring (for example airports and motorways). All the tests conducted so far by accredited universities and laboratories have shown excellent results in terms of increased performance and extension of useful life.

With the aim of better evaluating the greater durability of pavements containing Gipave, the University of Nottingham conducted a pavement design analysis, trying to simulate the real structural performance depending on the different types of road. Four recently resurfaced roads with different types of construction were therefore identified, from which the samples for the comparative analyzes conducted by the University of Nottingham were taken.

The simulation of the pavement design analysis highlighted that all sites demonstrate the effectiveness of the use of Gipave in extending the useful life. Furthermore, it was possible to produce a life cycle model of the infrastructure which highlights savings in CO emissions2 equal to 23 kg per m1,5 (on a stretch such as the experimental one in Dartford), as well as the recycling of over 32 tonnes of recovered plastic which is reused in the paving. Although the material is initially more expensive, the simulation showed a cost reduction of XNUMX% over the useful life.

In light of this research from the University of Nottingham, KCC plans to undertake work with Gipave on three further sites later this year with the aim of testing the material in different locations and on different road types. These trials will seek to replicate the test results of the Dartford trial, whilst also testing the commercial viability of Gipave. Depending on the results of these further tests, KCC will evaluate the use of Gipave to resurface some of its busiest roads in order to minimize disruption to the most sensitive sites, significantly reducing the need for maintenance interventions over time.
