Modified asphalt mixtures resistance to permanent deformations

摘要: Abstract Permanent deformations, primarily in the form of ruts, are one basic asphalt pavement damages impairing its service properties. Application appropriate mixtures and binder modification effective methods for improving courses resistance. While being manufactured, stored, fitted into a road during long term service, bitumen binders subject to continuous unfavourable ageing processes which characteristics change considerably, resistance permanent deformations among them. This article presents rut dynamic creep test results concrete, SMA (stone mastic asphalt), MNU (thin non‐continuous grain mixtures), Superpave mixture porous two air void content percentages: 15 %, 20 %. Asphalt concrete mixtures, MNU's contained elastomer, plastomer fine rubber modified binders. Samples laboratory tests were made by slab compaction beca...
