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. It allows for input of exposure conditions and blended cement use.
It is recommended to remove the old version before installing a new version
- CalAC v3.5 (ZIP, 4MB, last updated 01/16) CalAC is a Windows-based program to design rehabilitation alternatives for flexible pavements. This program follows a procedure similar to the MS-DOS version, ACREHAB. The recent changes in design policy have been incorporated into the new version.
- CalFP v1.5 (ZIP, 4MB, last updated 01/16) A Windows-based program to design new pavement alternatives for flexible pavments. This program follows a procedure similar to MS-DOS version, NewCON 90. The recent changes in design policy have been incorporated into the new version.
- CA4PRS (Construction Analysis for Pavement Rehabilitation Strategies) This software estimates how much pavement can be rehabilitated or reconstructed under different traffic closure strategies, considering project design and constraints and the number of lanes closed. The software provides a construction schedule baseline for the integrated analysis of pavement design, construction logistics, and traffic operations.
- RealCost v2.5CA Life-Cycle Cost Analysis (LCCA) is an analytical technique that is built on well-founded economic principles to evaluate long-term alternative investment options. 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.
- CalME is a software program developed by Caltrans/UCPRC using the Mechanistic-Empirical (ME) methodologies for analyzing and designing the performance of flexible pavements. 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. 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.
A web-based Version 3.0 of CalME is currently being developed. Beta Version 2.0 of CalME is available and a one-year evaluation license of the software can be obtained by contacting Imad Basheer at email@example.com.
CalME 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:
- Rehabilitation, pavement preservation and reconstruction
- New materials and in-place recycling
- Construction quality
- Integration with improved pavement management systems (PMS), such as the new system Caltrans is currently developing, which will begin to come into use over the next two years.
- 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. 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 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.
If interested in a one-year evaluation license of CalBack please contact Imad Basheer at firstname.lastname@example.org.
