Due to the intensive process of road construction or rehabilitation of pavement caused by an increase in traffic volume, in the field of rigid pavement design and research in Romania, we can say that there is a need to improve the design method. In the last decade, more and more researchers have been concerned about climate change and the increase in traffic volume; hence, there is a need for a renewal of the climatological, as well as traffic, databases because these are part of the input data for the design process. The design method currently used in Romania for jointed plain concrete pavement design is NP081/2002. The limitation of the data and the lack of lifetime estimation of structural and functional performance are the main aspects that need to be addressed in the new design procedure. The Mechanistic–Empirical Pavement Design (MEPDG) method offers the possibility of the design of pavement structures by estimating the structural and functional performances. This paper aims to obtain a comparative study of these two methods for the analysis of the input data collected from the field corresponding to the three failure criteria, while the symmetry of the characteristics of the material and their asymmetrical thicknesses are compared, thus contributing to the design of viable and long-lasting pavement structures using a rigid pavement with the specific characteristics of the mountainous area in northeastern Romania on the national road DN17 Suceava—Vatra Dornei. The novelty of this study consists of the implementation of the mechanistic–empirical method MEPDG instead of the old NP081/2002 method used in Romania.

基于半经验方法的刚性路面设计敏感性分析:罗马尼亚案例研究

由于交通量的增加导致道路建设或路面修复的密集过程,在罗马尼亚刚性路面的设计和研究领域,可以说有必要改进设计方法。在过去的十年中,越来越多的研究人员关注气候变化和交通量的增长。因此,需要更新气候数据库以及交通数据库,因为这些数据库是设计过程中输入数据的一部分。罗马尼亚目前用于接缝的普通混凝土路面设计的设计方法是NP081 / 2002。数据的局限性以及缺乏结构和功能性能的寿命估算是新设计程序中需要解决的主要方面。机械-经验路面设计(MEPDG)方法通过估算结构和功能性能,为路面结构设计提供了可能性。本文旨在对这两种方法进行比较研究,以分析从对应于三个破坏标准的现场收集的输入数据,同时比较材料特性的对称性和不对称厚度,从而有助于在罗马尼亚东北部DN17 Suceava-Vatra Dornei国道上,使用具有罗马尼亚特定山区特色的刚性路面,设计了可行且耐用的路面结构。这项研究的新颖性在于采用机械-经验方法MEPDG代替了罗马尼亚使用的旧NP081 / 2002方法。
