Evaluation of the durability of asphalt concrete on polymer modified bitumen

For research conduction to prepare the modified bitumen and the polymer asphalt concrete there were used the stone materials from the Malynsky enterprise and the mineral powdered lime, the petroleum paving bitumen of 60/90 grade from the Mozyrsky enterprise, and the Butanol NS 198 modifier. Conducted research showed that the asphalt concretes produced using the Butonal NS 198 meet the requirements to hot asphalt concrete and have higher strength and durability parameters. The polymer asphalt concrete design characteristics values change in sufficiently wide range depending on the binding agent amount shows the possibility of active regulation of its properties under the designing actual conditions. Higher water resistance and extended durability of these PACs ensure the preconditions of their use in different regions of Ukraine. Research results show that to get the maximum effect from the modifying agent application it is desirable to perform the scientist support during its field use and also the operational conditions monitoring to collect statistic data and carry out the necessary corrections to obtain the best results.
