The influence of the liquid low-viscosity additive (THPP) on the selected properties of the modified bitumen PMB 45/80-55

The main subject of the research introduced in this article is the influence of compaction temperature on lowering the amount of additive during production and installation of asphalt. The research assesses the effect of the addition of tetrachydropirymidupropyly (THPP) on selected properties of modified bitumen PMB 45/80-55. The content of THPP dosed in the range of 0.2 to 0.6% by weight of the adhesive, increasing the concentration by 0.2%. Based on the obtained results and the results of this analysis, conclusions have been drawn regarding the effects on selected parameters of modified asphalt.
