Thermal Stability Analysis under Embankment with Asphalt Pavement and Cement Pavement in Permafrost Regions
The permafrost degradation is the fundamental cause generating embankment diseases and pavement diseases in permafrost region while the permafrost degradation is related with temperature. Based on the field monitoring results of ground temperature along G214 Highway in high temperature permafrost regions, both the ground temperatures in superficial layer and the annual average temperatures unde...
متن کاملEffect of M-E design guide inputs on flexible pavement performance predictions
In support of the initiatives for implementing the new MechanisticEmpirical Pavement Design Guide (MEPDG) in Iowa, a preliminary sensitivity study was undertaken to assess the comparative effect of design input parameters pertaining to material properties, traffic and climate on performance of two existing flexible pavements in Iowa with relatively thick Asphalt Concrete (AC) layers. A total of...
متن کاملSensitivity Study of Design Input Parameters for Two Flexible Pavement Systems in Iowa Using the Mechanistic-Empirical Pavemen
Many agencies use the AASHTO Guide for Design of Pavement Structures to design their pavement systems. The limitation inherent in this method is the empirical nature of the decision process, which was derived from a road test conducted almost 45 years ago in Ottawa, Illinois. The newly released Mechanistic-Empirical Pavement Design Guide (MEPDG), based on NCHRP Study 1-37A, has adopted a mechan...
متن کاملGlobal Sensitivity Analysis of Mechanistic–Empirical Performance Predictions for Flexible Pavements
The new AASHTO Mechanistic–Empirical Pavement Design Guide (MEPDG) provides pavement analysis and performance predictions for various feasible design scenarios. The MEPDG performance predictions for the anticipated climatic and traffic conditions depends on the values of the input parameters that characterize the pavement materials, layers, design features, and condition. This paper focuses on ...
متن کاملEffect of Failure Criteria on Stress and Strain Analysis of Asphalt Pavement in Tropical Areas
A review of pavement thickness designs shows that two kinds of failure criteria are used in most cases. They are: 1) The tension strain under the asphalt layer that causes cracking and 2) the vertical compression strain on the sub-grade that causes deflection. In this study, various factors affecting thickness design are first defined and more than 216 pavement conditions are introduced. Struc...
