Forecast of Road Mixes’ Strength Properties with the Aid of Simulation Model.

Abstract

There were conducted trials of road mixes on the basis of bulk waste of production such as worked-out propping agent, regenerated zeolite, waste of terephthalic acid production (WTAP). On the basis of obtained data was developed simulation model for forecast of strength properties of road mixes at change of proportion of input components at following range: proportion of WTAP to bitumen from 0, 01 to 0, 04, zeolite to propping agent from 0, 6 to 1, 5, bituminous binder – mineral filler ratio from 0, 05 to 0, 1, as well as temperature, at which trials conducted from 0 to 50oC. Proposed model allows defining optimal proportion of input components, and thereby achieving high quality of road pavement.
