Resumen
The aim of the LORRY project is to reduce carbon footprint of truck transportation by developing an innovative low Rolling Resistance (RR) tyre concept combined with a comprehensive toolbox for fl¬eet fuel saving management. The ambition is that steering and trailer tyres developed in the framework of the project must demonstrate a minimum 20% reduction in truck tyre rolling resistance, which corresponds approximatively to a reduction of 5% in fuel consumption and CO2 emission. Truck tyre wear (10% improvement) and wet safety performance levels will also be additionally improved. This proposed concept is going beyond current state of art and stakeholder or market expectations regarding tyre rolling resistance, mileage, driving safety, driving performance and material and manufacturing sustainability. To reach this objective, a multidisciplinary approach has been initiated covering the fields of tyre technology, rubber and filler technology, nanotechnologies, composite physics, sensory, transport and road infrastructure. A complete set of complementary scientific evaluation methods enable the understanding of interactions between new tread pattern design and new material composites as well as the tyre performance dependency on tyre-vehicle operation and road conditions. Main novelties from this project are: Design of new tread pattern, Development of advancement nano-structured truck tyre compounds, Enhanced characterization through predictive tools: new testing methods and models, phenomena understanding at multi-scale and development of related predictive experimental and virtual analysis tools, Assessment of tyre performance ? field evaluation, Analysis and modelisation of tyre performance.
