Green sulfur-extended asphalt concrete: Mix design of the complex binder

Abstract

Using the ordinary sulfur extended asphalt leads to emission of toxic gases. The efficient method to prevent the emission is to use other admixtures as suppressors, but this requires the complication of the mix design scheme. In the present work we have extended the well known design method for the case of complex binder with arbitrary number of suppressors. The example of application of the proposed method is given. The results indicate that even for the relatively small amounts of suppressors it is better to use the correct mix design scheme.
