The aim of the project is to develop a new type of asphalt mixture, which exhibits superior safety characteristics of resistance to fire in road tunnels. It will also bring a certified test methodology for establishing the classes of materials according to their reaction to fire for asphalt pavements in tunnels. The project also focuses on finding optimal and economically acceptable surface fulfilling requirements for road tunnels, which will be supplemented by a software tool that conveys computational model for evaluating the thermal properties of the used materials.
The project objectives will be achieved by implementing fire tests in a road tunnel recess, data collection and evaluation, then fire model validation and simulation of fire tests for various alternative solutions to the tunnels. The resulting temperature characteristics serve as input data for the laboratory testing of selected materials, determining their reaction to fire and their classification according to the experimentally observed properties. Based on these findings, it will be a new type of asphalt mixture as the main outcome of the project, which will be reported with regard to the effect of high temperature peak characteristics and at the same time will reduce the fire safety of tunnels as such. New asphalt mixture will be ready to be applied to selected surfaces of tunnels. The main outcome of the project will be complemented by the aforementioned certified methodology and a software tool for the evaluation and classification of different types of materials.
