Bitumen V 12000-compliant with the requirements of EN 12591.
The products should be delivered in insulated road tankers, in a liquid state at an elevated temperature to ensure the required pumpability.
The temperature of the transported bitumen should be between 125 and 150 °C.
General safety rules for the transport of polymer modified bitumen according to ADR/RID regulations.
Road bitumen should be stored in insulated steel tanks with a heating system, closed, to protect the product from contamination and infiltration.
The maximum storage temperature should not be exceeded – see under specifications tab.
There are no known instances of storage instability where V12000 bitumen in the above storage conditions would lose the desired properties due to e.g. phase separation, However, storage at process temperatures of 125-150 °C should be minimised to prevent hardening of the bitumen due to ageing.
If storage under conditions not specified in this document is required, the manufacturer should be contacted to determine further handling of the product.
During the production, laying and compaction and laboratory testing of mineral and bitumen mixtures using road bitumen, it is recommended to use the process temperatures given in the table below.
Asfalty rodzaju V1500, V3000, V6000 i V12000 to miękkie lepiszcza stosowane do budowy nawierzchni drogowych na drogach o niskim natężeniu ruchu , głównie w krajach, gdzie występują bardzo ostre zimy (np. w krajach skandynawskich). Dla przykładu stosowany jest w Norwegii w rejonach, gdzie średnia roczna temperatura wynosi poniżej 6 st. C. Asfalty miękkie często stosowane są w technologiach z wykorzystaniem materiału z recyklingu: zarówno do podbudów (z mieszanki żwirowo-bitumicznej) jak również do produkcji mieszanek mineralno- asfaltowych z zastosowaniem asfaltu spienionego.
Asfalty miękkie V3000 i V6000 można również stosować do budowy i utwardzania dróg gruntowych o bardzo małym obciążeniu ruchem za pomocą mieszanek mineralno-asfaltowych z bardzo miękkiego betonu asfaltowego wg normy EN 13108-3, takie zastosowania powszechne są na Litwie i Łotwie.
