Quality Attributes And Complex Assessment Methodology of the Asphalt Mixing Plant

Multi-attribute methods in road construction can be used on the national, organizational, and project levels. However, most assessment methods are seeking to find how to make the most economic construction decisions, and most of all these decisions are intended only for economic objectives. Computerized Asphalt Mixing Plants (AMP) are one of the most expensive and complicated equipments for construction of road pavements. Modern AMP is controlling by computer program, but there are still some problems. Properties of the AMP not always satisfy demands and requirements of road constructors. Quality of the asphalt hot mixtures, environmental contamination, pollution, firm economic well-being, and possibility to satisfy demands of hot asphalt mixture users depend on the AMP quality. This paper proposes a multi-attribute model for efficient quality assessment of the AMP. For this problem 9 main quality attributes were selected and weighted by expert ranking method. The problem is solved by applying additive assessment. A case study is also presented.
