This paved a way for developing the software like IITPAVE which determines the stress and strains values at critical location at different layer of pavement. The failure of bitumen pavement is due to fatigue cracking and rutting deformation. Roads are used by different vehicle class which results in failure of the pavement due to early deterioration. CalBack has significant versatility via three deflection-matching search engines three response models for flexible pavements Westergaard model for rigid pavements and a large, self-contained, expandable material characterization database.Road transport plays a vital role in social, economic and industrial development of the country. CalBack contains specific features pertinent to California and is designed to work stand-alone, or in concert with the flexible pavement design and analysis software CalME. CalBack is a software developed by Caltrans/UCPRC to backcalculate layer moduli of flexible and rigid pavements using FWD deflection data collected from existing pavements.Rehabilitation, pavement preservation and reconstruction.CalAC-Web, CalFP-Web, and CalME V3.0 are hosted on the same website and share the same user interface.ĬalME is designed to maximize utility for the majority of the asphalt pavement work for which Caltrans, local government, and consultant engineers will use it by focusing on: At this time it is not available for private use it is only available to use for Caltrans projects. Instead, CalME simulates the pavement performance starting from the initial undamaged pavement stress, strain, and deformation responses to temperature and load to the end failure state.Ī web-based Version 3.0 of CalME is currently being developed and calibrated to accommodate wider range of materials. CalME uses an "incremental recursive" (I-R) approach that models the entire damage process, not just the initial condition after construction and the final failure condition. CalME is a software program developed by Caltrans/UCPRC using the Mechanistic-Empirical (ME) methodologies for analyzing and designing the performance of flexible pavements.The analysis enables the total cost comparison of competing pavement design (new or rehabilitation) alternatives, each of which would be appropriate for implementation to the roadway being considered.

RealCost v2.5CA (ZIP) LCCA (Life-Cycle Cost Analysis) is an analytical technique that is built on well-founded economic principles to evaluate long-term alternative investment options.Please follow the link and register an account to start using the program.ĬalAC-Web and CalFP-Web has been verified to produce results consistent with CalAC and CalFP, respectively.

The recent changes in design policy have been incorporated into the new version. This program follows a procedure similar to Windows-based version, CalFP.

This program follows a procedure similar to the Windows-based version, CalAC. CalAC-Web (Updated 04/02/19) CalAC-Web is an online program to design rehabilitation alternatives for flexible pavements.Users will need to make their own determinations as to whether or not this software is appropriate to use. * Note - These Applications can perform Directory Traversals, (can access folders that are not in the same directory/file) and can be interpreted by some tools as Malware. Web-Based CalAC-Web and CalFP-Web for Flexible Pavement Thickness Design It allows for input of exposure conditions and blended cement use. SCM Evaluation (Feb 10, 2011, 44KB, MS-Excel)This spreadsheet tool is useful for evaluating if a submitted concrete mix design conforms to the 2009 specification for concrete.
