Abstract. This paper focuses on evaluation of two laboratory-based methods of compaction of foamed bitumen and bitumen emulsion mixes: impact compaction with a Marshall hammer and static compaction using a hydraulic press. The investigated compaction methods were assessed in terms of their impact on the physical and mechanical properties of produced laboratory specimens, including: air void content, indirect tensile strength before and after conditioning in water (ITSdry, ITSwet), tensile strength ratio (TSR), and indirect tensile stiffness modulus (ITSM) at 0• C, 10• C and 20• C. The statically compacted specimens attained higher levels of mechanical properties and resistance to moisture damage, which was associated with a lower content of air voids in the specimens formed using a hydraulic press. Authors present a calculation showing that a mechanistic design based on the laboratory static press compaction method leads to overestimation of fatigue cracking resistance of the road base.

“…As a next step, polymer modified bitumen with extended temperature range of viscoelastic properties was used in increasing number of road contracts . Currently, Poland is a European leader in terms of a number of a pavement construction projects (Radziszewski et al 2012). On-going construction and re-construction program includes works on a various types of roads: from local to the trans-European corridors.…”

Construction of modern and durable bituminous pavements requires high quality bituminous binder, aggregates and additives. The main objective of this paper was to analyse and compare viscoelastic properties of unmodified and polymer modified bitumens produced in Poland, Europe, in order to assess their quality. In this paper there are presented results of bituminous binder European classification tests (penetration, softening point and Fraass breaking point) as well as rheological test results conducted over a wide range of temperatures. In addition, image analysis of the microstructure of selected polymer modified bitumens is also presented. Based on the analysis it was concluded that although bituminous binders complies with European specification requirements, they are significantly different in terms of their rheological properties. It was found that regardless of binder producer, bituminous binder within the same hardness group exhibit different low and high temperature properties.
