Abstract
One of the key properties related to the durability of a road pavements are the parameters related to water and frost resistance of the asphalt mixture as well as the bitumen binder itself. This is particularly important in the climatic conditions prevailing in Poland, where there is large number of passes through zero degrees Celcius, so that the pavement is subjected to repeated cycles of freezing and thawing, which, together with water penetrating deep into the road structure, has a highly destructive effect. In addition, most of the mineral and asphalt mixtures offered on the market are “hot mix” products produced at high operating temperatures with significant levels of emissions of various pollutants as well as high energy consumption. Hence, it is important to look for alternative, environmentally friendly technologies, including those using waste materials. In the presented research, the effect of the addition of two porous materials of waste origin on selected properties of bitumen was analyzed together with the feasibility of mineral-asphalt mixtures using foamed bitumen technology with satisfactory water and frost resistance parameters as well as reduced operating temperatures. In view of the need to improve the adhesion of bitumen to aggregate, which translates directly into water and frost resistance, the selection of suitable agents in order to improve this parameter was also conducted on the basis of affinity tests. The presented results showed the application suitability of waste origin porous materials for the asphalt mixtures production with an environmentally and economically friendly character. Produced mixtures were also characterized by comparable water and frost resistance parameters to those of mixtures produced by conventional technology.
