FROM THE LABORATORY TO THE WORKSITE, AN INNOVATIVE SPREADING TEST BENCH FOR BITUMEN EMULSIONS

The development of new products or processes in road building does not end simply with laboratory tests and results. These fail to take many parameters into account, as it has recently been witnessed in the case of surface dressing. To overcome this problem a spreading test bench has been built to help laboratory scientists compare the on-site behaviour of different bitumen emulsions. The machine, moving on rails at a rate of between 1 and 6 km/h, is able to spread bitumen emulsion, additives and aggregate onto different kinds of substrate, with an experimental area covering 10 metres in length and 1.2 metres in width. Different weather conditions can be simulated on the apparatus. This apparatus, entirely monitored by a computer, is used for the optimization of existing techniques and the development of new techniques involving bitumen emulsions. An example describes how this experimental apparatus could improve tack coat emulsion spraying processes; the breaking rate of the emulsion and the adhesion of the film to the support are related to the type of bitumen, the type of the emulsifier, and the state of the substrate. For the covering abstract see ITRD E107185.
