Comprehensive Evaluation on Technical Economic Performance and Scheme Optimization for Asphalt Mixture
The pavement performance of asphalt mixture and its adaptability to features of application area, cost estimation and harmonic relationship between performance and cost were studied and analyzed in this paper, evaluation model of technical and economic performance of asphalt mixture was constructed, evaluating indicators of technical and economic performance of asphalt mixture as performance matching coefficient, cost conversion demarcation coefficient and harmonic factor of performance and cost and corresponding calculation methods were proposed. On this basis, discrimination function of performance and cost was built to provide theoretical basis and decision support for selecting a satisfactory asphalt mixture scheme which had the best pavement performance and economic performance under certain natural and constraint conditions, it can provide a reference for the development of assist decision function of managerial system of pavement maintenance as well.
