Svojstva mješavina za izradu nevezanih nosivih slojeva s dodatkom recikliranog asfalta

Abstract

The possibility of using recycled asphalt as replacement for natural aggregate in unbound base course mixes is explored in the paper. The mixes in which a certain proportion of natural aggregate (limestone, gravel) was replaced with recycled asphalt were analysed. The testing program involved analysis of the grading, compaction parameters, physicomechanical properties and bearing capacity of mixes. The results show that recycled asphalt can be used, in some proportions, as a suitable replacement for natural aggregate.

Mastic asphalt modified with recycled polyurethane foam

“…Successful results have also been achieved by adding this material to asphalt mixes [25]. Reclaimed asphalt pavement (RAP) is a very commonly reused material, and it is mainly employed in subbase layers and bituminous layers [26][27][28][29]. AC with high proportions of RAP can exhibit similar mechanical performance [30].…”
