The pavement engineering and science program has been very active in developing software for the pavement community. The Window-based version of the 3D-Move Analysis software to compute pavement responses, which has been developed under a cooperative agreement with FHWA, is one of those distinctive software.

The 3D-Move model has the ability to distinctly account for important pavement response factors such as moving vehicle loads, three dimensional contact stress distributions of any shape, and viscoelastic material characterization for the pavement layers. Furthermore, it is the only currently available pavement analysis software that can incorporate the braking effect that occurs at intersections. The software is currently being used by over 450 users from more than 45 countries.


We have also developed a new software program that predicts the hourly temperature at any depth in the asphalt pavement for any location in the United States. The software, called Temperature Estimation Model for Pavement Structures (TEMPS), is the only one of its kind and can have numerous applications in pavement engineering. For example, the TEMPS software has generated a great interest by the National Asphalt Pavement Association (NAPA) for potentially identifying cool pavements technologies to mitigate urban heat island effects. 

ARC database

As part of the Asphalt Research Consortium (ARC) project sponsored by FHWA, the University of Nevada, Reno designed a web-based database management system and application that will allow consortium members to store research results related to materials, material properties, material measures and results of laboratory and field testing. The data will also be available to the general public via a searchable web-based interface. It is expected that university researchers and students, along with industry professionals and public agencies, will greatly benefit from this data.

The system is implemented using well-adopted technologies including Microsoft SQL Server and Microsoft ASP.NET. The database and application are currently being hosted at the University of Nevada, Reno. Recently, FHWA agreed to adopt and implement the database structure internally for storing and coordinating pavement related research data generated by various programs and divisions within FHWA.



The movement of superheavy loads (SHLs) has become more common over the years, since it is a vital necessity for many important industries, such as chemical, oil, electrical, and defense. SHL hauling units are much larger in size and weight compared to standard trucks. SHL vehicles' gross vehicle weights may be in excess of a few million pounds, so they often require specialized trailers and components with nonstandard spacing between tires and axles. Accommodating SHL movements requires the determination of whether the pavement is structurally adequate and involves the analysis of the likelihood of instantaneous or rapid load-induced shear failure. As part of the Federal Highway Administration project DTFH61-13-C-00014, Analysis Procedures for Evaluating Superheavy Load Movement on Flexible Pavements, an analysis package (alpha version), Superheavy Load Vehicle Movement on Flexible Pavement (SuperPACK), was developed to evaluate specific cases of SHL-vehicle movements. SuperPACK is developed in MATLAB as a stand-alone software package.

SuperPACK comprises three components: pre-analysis modules (A modules), analysis modules (B modules), and an analysis engine (3D-Move ENHANCED). The A modules, which are required to proceed to the B modules, require information on vehicle axle configurations, material properties, subgrade shear strength parameters, and representative material properties for the analysis and reference vehicles. The B modules conduct bearing capacity, service limit, slope stability, buried utility, and cost allocation analyses. All the A and B modules require pavement responses, excepting the module on vehicle axle configurations. 3D-Move ENHANCED was developed to provide the modules with responses based upon the request. The analysis engine is based on the original formulation of 3D-Move. However, several enhancements to the original formulation were incorporated in the SHL-vehicle movement analysis. For instance, runtime was improved using inverse Fourier transform, and parallel processing techniques were implemented so that different axle groups of an SHL vehicle could be analyzed in a reasonable amount of time.

The SuperPACK main window contains general information about the project, as well as basic information needed for a 3D-Move ENHANCED analysis (e.g., layer thicknesses, material types). The A and B modules can be accessed through the SuperPACK main window. A function and GUI were specifically developed for each module. Each GUI collects specific information needed to execute its corresponding module. Additionally, 3D-Move ENHANCED provides the modules with the necessary pavement responses when requested. The A and B modules share information through the SuperPACK main window.


Vehicle Operating Costs (VOCs) Calculator

Considerable changes in vehicle technology over the past several decades resulted in an emerging need for improved fuel and non-fuel vehicle operating costs (VOCs) estimations for use in benefit-cost analyses. The University of Nevada, Reno completed the FHWA DTFH61-14-C-00044 study to enhance the predictions of VOCs. The University of Nevada team comprised the Nevada Automotive Test Center (NATC) and Dynatest Consulting Inc. subcontractors.

The University of Nevada, Reno funded and designed a web-based application that will allow users to estimate VOCs including, fuel consumption, tire wear, oil consumption, mileage-related vehicle depreciation, and repair and maintenance costs. It is expected that university researchers and students, along with industry professionals and public agencies, will greatly benefit from this application. The application is currently being hosted at the University of Nevada, Reno.
