ABSTRACT:

The challenge now facing agencies winter road maintenance is to ensure the levels of safety on our roads more efficiently and responsibly with the environment. To achieve this must apply new technologies that are able to monitor and predict the state of pavement along the entire route of the road, and consequently decide preventive treatments (eg salt dosing) most suitable for each segment .

This article describes the fundamentals of measurement and the implementation of two prototypes of optical sensors, designed to measure remotely and shipped in maintenance vehicles the local parameters of greatest relevance for winter roads: amount of water (and / or ice) and residual salinity on the pavement surface.
