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 (RealCostV2.5.6CA.zip, 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.
CA4PRS (Construction Analysis for Pavement Rehabilitation Strategies) Software
Most state highways in the United States, built during the 1960s and 1970s and
outliving their 20-year design lives, have become seriously deteriorated. Consequences
of these degraded road surfaces are high maintenance and road-user costs and construction
work zone delays. This situation makes efficient planning of highway rehabilitation
The CA4PRS input interface integrates design, construction, and traffic.
CA4PRS (Construction Analysis for Pavement Rehabilitation Strategies) software
aids engineers and contractors in selecting economical highway rehabilitation strategies
that minimize disruptions to drivers and to the surrounding community. This powerful
software program provides highway rehabilitation professionals with the ability to
identify optimal rehabilitation strategies that balance construction schedules with
road-user inconvenience and transportation agency cost by considering “what
if” scenarios for variables such as:
- Rehabilitation strategy
- Construction window
- Number of lanes to be closed for rehabilitation
- Material selection
- Pavement base type, and
- Contractor logistics — including site access and production rates
Developed by the University of California Pavement Research Center (UCPRC) under a
Federal Highway Administration (FHWA) pooled-fund study for California, Florida,
Minnesota, Texas, and Washington State, CA4PRS was designated as a “priority
technology” by the American Association of State Highway and Transportation
Officials' (AASHTO) Technology Implementation Group in 2006.
CA4PRS software has been successfully field-proven on a number
high-traffic volume urban freeway rehabilitation projects, including projects on I-10
and I-710 in Southern California. Technical information is available on
Division of Research and Innovation Web site or at
the FHWA FOCUS journal Web site.
The article, “Accelerated
Reconstruction Of I-15 Devore Corridor,” appearing in the FHWA’s Public
Roads magazine (January/February 2007) explains the key role CA4PRS played in the
innovative Caltrans I-15 Devore Project in Southern California.
CA4PRS won the 2007 Global Road Achievement Award from the International Road Foundation.

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.
