Web-Based CalAC-Web and CalFP-Web for Flexible Pavement Thickness Design
* 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. Users will need to make their own determinations as to whether or not this software is appropriate to use.
CalAC-Web (Updated 04/02/19) CalAC-Web is an online program to design rehabilitation alternatives for flexible pavements. This program follows a procedure similar to the Windows-based version, CalAC. The recent changes in design policy have been incorporated into the new version. Please follow the link and register an account to start using the program.
CalFP-Web (Updated 04/02/19) CalFP-Web is a program to design new pavement alternatives for flexible pavements. This program follows a procedure similar to Windows-based version, CalFP. The recent changes in design policy have been incorporated into the new version. Please follow the link and register an account to start using the program.
CalAC-Web and CalFP-Web has been verified to produce results consistent with CalAC and CalFP, respectively.
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. 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 and calibrated to accommodate wider range of materials. At this time it is not available for private use; it is only available to use for Caltrans projects. CalAC-Web, CalFP-Web, and CalME V3.0 are hosted on the same website and share the same user interface.
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
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.
The Asphalt Institute has discontinued the SW-1 Thickness Design & SW-2 Mix Design software packages. Gb instruments circuit alert gvd 504a manual. There is no plan to update either software package.
See the Recommended Thickness Design Software section below for current and robust alternatives to SW-1. Regarding mix design software, many State DOTs have their own required software to be used, and several lab equipment manufacturers have alternatives as well.
The Asphalt Institute is allowing SW-1 and SW-2 to be downloaded free of charge. However, Seat ibiza 6j service manual. No support is offered or available for the SW-1 or SW-2 software package. Responsibility for installation and usage is accepted by the user when clicking either application’s download link below.
Application Notes
The files downloaded by clicking either link below is a ZIP containing an ISO CD image.
You will need CD/DVD drive emulation software to access the ISO file(s) to install/run the applications. AI does not endorse any specific CD/DVD drive emulation software but this Google Search results page should get you started.
Installers and applications are likely to run best when operated in “Windows XP SP2” Compatibility mode.
SW-1 will require a one-time unlock key be generated. Once the application is installed, the first time it is run, the splash screen will display an 18-digit code. Email that code to [email protected] to receive an unlock key.
The Heavy Wheel Load (HWL) module in SW-1 has some glitches, so the Manual MS-23 should be used instead.
