You are viewing a legacy version (3.DD001.3) of CalME. It is expected that additional pavement distresses will be added in future versions of CalME.Ī list of acronyms used throughout CalME is located in the online help system. In CalME, the module’s predicted distresses include fatigue cracking, reflective cracking, rutting, and smoothness. This module and the pavement distresses included in it can vary from one ME design system to another, depending on the specific project. Highlights of work that the Caltrans/UCPRC Partnered Pavement Research Center (PPRC) started, completed, or implemented during the 2021-2022 fiscal year. CalME exercises an 'incremental recursive' (I-R) approach that models the entire damage process, not just the initial exercise after construction and the latest failure condition. A key component of any ME design system is a module that predicts the performance of a given pavement design. 2021-22 Annual Report Released: Partnered Pavement Research Center Annual Report: Fiscal Year 2021-2022 (PDF). CalME is an software program developed by Caltrans/UCPRC using the Mechanistic-Empirical (ME) methodologies for evaluating and designing the driving of flexible fahrbahn. California Highway Design Manual: 650 - Pavement Drainage California Highway Design Manual: 830 - Transportation Facility Drainage Geosynthetics. ME design is an iterative process in which trial pavement designs are adjusted repeatedly either manually or automatically based on predictedperformance until an optimal design is reached. This web application is used to design pavement structural sections using the Mechanistic-Empirical (ME) methodology.
