Abstract
The purpose of the study was to investigate the ratio between air void content and volumetric properties related to the dielectric values of asphalt. This information was supposed to contribute to a bigger project commissioned by the Finnish Transport Agency. The followed test method was to compact the samples by gyratory compaction, measurement of the densities and calculation of the volumetric properties and measurement of the dielectric values. The target height dimension of the samples was 125 mm. A large testing program of 18 cut samples was carried out in the laboratory of Highway Engineering. In first place Stone Mastic Asphalt 16 was the material used. Because of problems and obstacles found out while it was being used, the material was changed to Asphalt Concrete 16. The obtained values for the dielectric values and for the volumetric properties studied only gave one approximation of one relation already discovered but other studies. Furthermore, not more important conclusions could be observed in the results.
