30,000 km of Structural Road Surveys in One Year. Challenges of Large Road Network Auscultation and Management

The present text explains how to carry out an auscultation or monitoring of the structural characteristics of a large roadway network using high-performance equipment and the use of the data collected for the management of these roadways. The monitoring is carried out using high-performance MT Curviameter equipment at a speed of 18 km/h (11.18 mi/h) and taking measurements every 5 m (16.40 ft), which allows collection of a great deal of information. Every 5 m (16.40 ft) this equipment determines the maximum deflection, the curvature radius and the deflection basin, defined by sampling 100 points at each measurement. Additionally, the system measures ambient and road surface temperature and even incorporates high-resolution panoramic images to the measurements. The data management system allows users to identify zones having homogenous behaviour (according to the applicable standards in each country) and detects specific points with reduced load capacity. The data obtained during monitoring are entered into information systems specifically designed for roadway network monitoring. These incorporate applications based on Geographical Information Systems which allow fast and easy management and access to the data. With this system the structural condition of the roadway network surveyed can be determined, and both needs and repair priorities can be established. Finally, it should be noted that this equipment has been incorporated into the road construction process with the aim of monitoring the various layers of the pavement and of using the data acquired during roadway construction as a base for conservation measures.
