The Application of the Best-Worst Method to Gain the Premier Modified Asphalt Mixtures
The main purpose of Hot Mix Asphalt (HMA) is to choose the most suitable and the most affordable mix of bitumen and aggregates, so that it can maintain the technical properties of the asphalt concrete in certain amounts. Different methods have been suggested for mixing the Hot Mix Asphalt (HMA) incl...

| description | The main purpose of Hot Mix Asphalt (HMA) is to choose the most suitable and the most affordable mix of bitumen and aggregates, so that it can maintain the technical properties of the asphalt concrete in certain amounts. Different methods have been suggested for mixing the Hot Mix Asphalt (HMA) including the Marshall method, the modified Marshall method, Hveem method, and the Superpave mixing method. Concurrently, the project of mixing Hot Mix Asphalt (HMA) in Iran is done based on the Marshall method and the modified Marshall method. Regarding the weaknesses of the asphalt mixes in different situations, the engineers try to modify and improve the properties of the asphalt mix by use of different additives. On the other hand, the additional expenses of various additives to the asphalt mix for building one kilometer of the road is a negative parameter. However, by use of the additives, the technical properties of the asphalt mix improve. Therefore, to decide on a proper choice out of the alternatives would be a difficult task. This paper, tries to provide an appropriate method for evaluating and choosing the best alternative by taking into consideration all the technical criteria. In this article, we first evaluate the score and the weight of each alternative in each criterion. Then, the weight of each criterion is evaluated using the best-worst method, and eventually, taking all aspects into consideration, the rankings of different alternatives will be determined based on two situations: certain situation and uncertain situation. |
