In the field of road construction, several projects have been developed over the last couple of years. The most representative project was the EU Computer Integrated Road Construction (CIRC) project (1997-1999) that dealt with the development of a new generation of autonomous road pavers and asphalt compactors [4]. These mobile machines (robots) extensively used GPS-based tracking technology for autonomous navigation. [5]. In road construction, the quality of the compacted material (asphalt) is essential and depends on the number of runs of the compactor and the uniformity of the energy distribution. Field management of the hot-mix asphalt process [6] is another important field of research in this area.
