  4. This paper, regarding the asphalt pavement in the zhoukou region as the study object, according to the prevalent norms ( specifications for design of highway asphalt pavement ), with the beginning of the pavement performance and the transportation investigation, totally and systematically analyzes the traffic parameters and the destroying reason of pavement at the early stage in the point of fatigue property and limit strength, gives the concepts and methods of the growth rate of equivalent axle load action time, seasonal modification factor and overload factor, proposes the method of axle load conversion on the condition of heavy loading. on this basis, it proposes the design method adapting to asphalt pavement construction, explains the steps of thickness computation of construction with the combination of engineering example, finally verifies thedesign method in the paper by test road. theory and practice both prove that the reasonability of pavement structure style and the reliability of design method in the paper can adapt to the present heavy loading and overloading traffic conditions, have highly theoretical and practical value

    本文以周口地區瀝青路面為研究對象,以現行《公路瀝青路面設計規范》為依據,從路面使用性能和交通特徵的調入手,從疲勞特性和極限強度出發分析了路面早期破損的原因,全面系統地進行了交通參數的分析,提出了當量軸次增長、季節修正系數和超載系數的概念和方法,並提出了重載交通的軸載換算方法。在此基礎上,針對超載、重載交通從結構組合設計、結構厚度計算(包括疲勞強度標和極限強度標)等方面提出了適宜的瀝青路面結構設計方法,並結合工程實測,說明了結構層厚度計算的具體步驟,後通過試驗路驗證本文提出的設計方法。理論與實踐均表明,本文提出的路面結構型式合理、設計方法可靠,能適應目前重載、超載交通的狀況,具有較理論與實用價值。
