Abstract:

In 1971 a test road with an expanded polystyrol (EPS)-concrete base was constructed in Austria at an altitude of about 1000 m above sea level. The expanding of the raw material and the production of the concrete took place on the construction site. During several years the test road was intensively investigated. Recently, interest in this construction method has grown again because of an abundance of available recycled EPS from the packaging industry. Above all, the analysis of the measured data of that time has shown that the EPS-concrete base almost completely prevented the penetration of frost into the subsoil. This was advantageous in view of an approximately uniform bearing capacity in the course of the seasons. Compared to the usual standard structure however, there was a slightly increased risk for the formation of black ice in winter and ruts in the asphalt during the summer. Part of the concealed joints that were laid out at the time of the construction of the EPS-concrete base are now visible as reflection cracks at the surface of the 18.5- or 22.5-cm-thick asphalt overlays. Further tests should help to find out whether it is possible to do without these transverse concealed joints.
