The Pavement Research Center designs, develops and maintains various reseach class software applications. The following is a partial list.


RealCost-CA (version 2.5.6) is a software program to run life cycle cost analysis (LCCA). This software is based on a Microsoft Excel Macro function (64-bit). The download file is a zip compressed file (, 2.4 Mb). It does not require a system administrator's permission, unlike the previous version.

Pavement ME Design Traffic Input Tool

Pavement ME Design Traffic Input (v1.0.0) generates traffic information (axle load distribution for single, tandem, and triple axles) and other inputs (vehicle class distribution, hourly distribution, axles per vehicle class, and annual average daily truck volume) for a project-specific location on the California highway network system, based on the Weigh-in-Motion (WIM) axle load spectra analysis results. The traffic files generated by this tool can be used directly as input for AASHTOWare's Pavement ME Design software. This software is a Microsoft desktop application (32-bit). The download file is a Setup msi file (Pavement ME Traffic Input Setup.msi 9.1 mb). The installation requires system administrator's permission.

CalME Pavement Design Tool

CalME: Caltrans Mechanistic-Empirical Structural Analysis Program for Flexible Pavements, v3.0 is a web application for analyzing pavement structural sections using the Mechanistic-Empirical (ME) methodology. This is the official structural analysis program used by Caltrans (California Department of Transportation) for flexible pavements. It is used for new construction and rehabilitation including overlays.

The eLCAP data library has been developed based on the California-specific inventories of materials and mixes, construction equipment and activities, transportation modes, and use-stage impacts with consideration of pavement vehicle interaction and traffic congestion. The database is built in-house (UCPRC) to represent local conditions to the extent possible, by using California’s electricity grid mix and fuels and following local practices in production, mix design, and construction.

eLCAP computes 18 different impact category values which include Primary Energy Demand used as Raw Materials (feedstock energy), Primary Energy Demand from Renewable and Non-renewable Resources (gross and net caloric value, separately), Primary Energy from Nonrenewable Resources (gross and net caloric value, separately), Primary Energy from Renewable Resources (gross and net caloric value, separately) and United States Environmental Protection Agency’s Tool for Reduction and Assessment of Chemicals and Other Environmental Impacts (TRACI); Acidification, Ecotoxicity, Eutrophication, Global Warming Air (excluding and including biogenic carbon, separately), Human Health Particulate Air, Human toxicity (cancerous and non-cancerous, separately), Ozone Depletion Resources, Fossil fuels, and Smog Air.

eLCAP: Environmental Life Cycle Assessment Tool for Pavement

eLCAP™: environmental Life Cycle Assessment for Pavements Tool eLCAP is a web-based transport infrastructure life cycle assessment tool that has the capability to model the life cycle history of a pavement project by allowing a user to specify any number of construction events, occurring at a user-specified date, followed by an automatically generated Use Stage event that begins immediately afterward and lasts until the next construction event or the End-of-Life date.

The Pavement Program’s Office of Asphalt Pavements in the Division of Maintenance, partnering with the University of California Pavement Research Center (UCPRC), developed this program, specifically for the Caltrans highway system and traffic conditions. The models are calibrated using pavement condition data collected over the past 20 to 30 years in PaveM.

MultiCool is a software program that enables the user to calculate the temperature profile of multilayer asphalt hot mix pavements under a variety of environmental conditions and timing constraints. The download file is a self-extracting archive containing a help file, an executable file, and a data file. (MultiCool.exe 369kb). Note that MultiCool is freeware and that UCPRC does not provide support for it.
