การประยุกต์ใช้แบบจำลองการเสื่อมสภาพของผิวทางลาดยางในถนนที่มีปริมาณจราจรต่ำโดยวิธีลูกโซ่มาร์คอฟเพื่อการวางแผนงานบำรุงทาง

Abstract

The purpose of this research is to apply the use of deterioration model of flexible pavement in low traffic volume roads using Markov chains for pavement maintenance planning of the Department of Rural Roads. In this research, the International Roughness Index was used to represent pavement condition and the models were grouped by the factors that impact the pavement damage such as average annual daily traffic, number of heavy truck, rainfall volume, and pavement types. To apply the model, it is necessary to develop the relationship between the pavement age and the International Roughness Index which is the expected value of multiplying the transition matrix. And the relationship can be used to predict the pavement condition or applied to many purposes of pavement maintenance planning.
