Analysis of Weighing Values of Post-Assessment Indexes for Graded Crushed Stone Base Based on Analytic Hierarchy Procedure

Based on analytic hierarchy procedure, established the post-assessment indexes system of graded crushed stone base project. Considering the road performance and economic benefit, societal and environmental benefit, the weighing values for various layers factors group of the graded crushed stone base project of Heng-Gai line are calculated. Analytic hierarchy procedure (AHP) method can effectively avoid making decisions subjectively and more scientific and reasonable to determine the weighing values of post-assessment indexes and it is an effective method to determine the weighing values for post-assessment indexes of the graded crushed stone base project.
