A Design Method of Pavement Pavement Scheme

Abstract

The invention relates to a decision-making method of a pavement laying scheme. The method includes estimating corresponding indicators related to pavement characteristics, economic characteristics and emission characteristics in each pavement laying scheme; The small attributes are standardized separately to obtain the corresponding standardized index values; the index weight coefficients corresponding to each index are set, and the weight coefficients and standardized index values ​​are set and calculated to obtain the comprehensive evaluation value of the corresponding road paving scheme. The pavement paving scheme with comprehensive evaluation value shall be the final scheme adopted. Its advantage is that comprehensive decision-making is made on pavement design from a variety of factors, and the performance of life cycle is considered in pavement characteristics, so that pavement design has better cost performance, and more scientific, economical and environmentally friendly pavement can be formulated Design scheme; at the same time, the calculation process is simple and can objectively and quantitatively give the required data.

Description

technical field [0001] The invention relates to pavement laying, in particular to a design method of a road paving scheme. Background technique [0002] Traditional road design only considers factors such as pavement carrying capacity, satisfaction of functional requirements, and construction cost accounting when determining the design scheme. After long-term road use verification, the pavement scheme designed under this design concept will be used later. There will be such a problem that the maintenance cost often exceeds the cost of the initial construction. This is because the traditional road design ignores that the road is a long-term use product, and only analyzes the pavement performance and construction cost in the initial construction process in the decision-making of the plan, but does not consider the pavement performance and economics required for the entire life cycle of the road. Comprehensive and comprehensive consideration, not to mention the impact of energ...

This is because the traditional road design ignores that the road is a long-term use product, and only analyzes the pavement performance and construction cost in the initial construction process in the decision-making of the plan, but does not consider the pavement performance and economics required for the entire life cycle of the road. Comprehensive and comprehensive consideration, not to mention the impact of energy consumed during road construction on environmental emissions, so the current road design and decision-making lacks the requirements for road surface performance from the road life cycle and the requirements for environmental emissions in the early stage of construction, so that it cannot Get a truly fully optimized pavement design plan
