Pavement maintenance scheme decision-making method based on life cycle cost analysis

Abstract

The invention belongs to the field of road maintenance engineering, and particularly relates to a pavement maintenance scheme decision-making method based on life cycle cost analysis, which comprisesthe following operation steps: S1, determining a functional unit; S2, determining a maintenance opportunity; S3, evaluating the time value of funds, and carrying out economic analysis on the initial construction cost, the operation period management and maintenance cost, the environment cost and the residual value index in the life cycle of different maintenance schemes; S4, performing life cyclecost analysis. According to the pavement maintenance scheme decision-making method based on life cycle cost analysis provided by the invention, the concepts of life prediction and life cycle cost arecombined; the decision of a maintenance scheme in highway engineering is more reasonable, engineering construction, the service level of the service life and long-term investment control are guaranteed more powerfully and comprehensively, road management and maintenance funds are used more reasonably, and the cost performance is higher.

Description

technical field [0001] The invention belongs to the field of road maintenance engineering, and in particular relates to a decision-making method for road surface maintenance schemes based on life cycle cost analysis. Background technique [0002] At present, my country's road network has been relatively perfect, and road construction has gradually entered a period of steady development. The maintenance and management of existing road surfaces will become the focus of transportation development at this stage. With the rapid economic growth, the traffic volume is increasing day by day, and the vehicle load is constantly accumulating, making the road surface also bear unprecedented pressure. The increasing number of road surface diseases not only affects the service quality of the highway, reduces the transportation efficiency of the road network, but also seriously affects the economic development of the region. Therefore, it is necessary to improve this situation through nec...

Problems solved by technology

In the past, the economic evaluation of the maintenance plan was relatively one-sided, and generally only focused on the initial construction cost, and seldom considered factors such as the subsequent daily maintenance and repair costs of the road. Often, the initial construction cost of the selected plan was low, but the life-cycle cost was high.
