Stochastic simulation of the influence of reclaimed asphalt pavement mineral material aggregate variation on the homogeneity of recycled hot-mix asphalt

Abstract

Nowadays flexible pavement used for roads more and more often consists of hot mix asphalt, made in central asphalt mixing plant including granules of reclaimed asphalt pavement. The quantity of reclaimed asphalt pavement to be added depends on its homogeneity. The article presents the algorithm to prognosticate the mineral part composition of hot-mix asphalt, taking into consideration the variation of reclaimed asphalt pavement mineral material grading. The reclaimed asphalt pavement mineral grading is selected through the use of a random number generator. The example of simulation is presented and the results are analysed.
