Hållbar utveckling av vägsektorn
(2018)- Abstract
- To create a society with sustainable development the use of our planets finite resources has to change, this is no less true for us in infrastructure. Every year thousands of tonnes of asphalt paving is ground up and most of it is not reused. The knowledge regarding the recycling of asphalt has gone forward recent years and today there is a couple of different dopes that claim to be able to reduce the use of greater volumes of recycled asphalt, this study intend to analyse one such dope “ZycoTherm”. The dope allegedly improves the bitumens adhesive properties, it is not a “rejuvenator” which try to restore lost properties of the binder. This also means that the use of other, finite, adhesives like cement can be reduced. The laboratory work... (More)
- To create a society with sustainable development the use of our planets finite resources has to change, this is no less true for us in infrastructure.

The knowledge regarding the recycling of asphalt has gone forward recent years and today there is a couple of different dopes that claim to be able to reduce the use of greater volumes of recycled asphalt, this study intend to analyse one such dope “ZycoTherm”. The dope allegedly improves the bitumens adhesive properties, it is not a “rejuvenator” which try to restore lost properties of the binder. This also means that the use of other, finite, adhesives like cement can be reduced. The laboratory work is for the most part done by us at NCCs facilities outside of Södra Sandby and the tests include penetration and softening point for the binder and abrasion permanence (according with the prall-method) and moisture susceptibility for the asphalt. In addition a questionnaire study was performed on the personnel of NCC who pave the roads, this because complaints have been raised that the asphalt batches containing ZycoTherm are “harder” to work with. The results of the study showed no real improvements in the tests penetration and softening point for the binder and abrasion permanence for the asphalt. The result for water susceptibility, however, showed clearly that ZycoTherm improved the tensile strength for asphalts containing recycled asphalt. This can lead to positive changes for our society when recycled asphalt can be used to a much greater extent than it is today. (Less)
