Atlas Solar Simulator

Atlas Solar Simulator

The Carleton Laboratory solar simulator is a purpose-built room with a temperature-controlled exhaust system, which cools the room by forced-air ventilation. The SolarConstant lamp is mounted to modular tracks located on the ceiling of the chamber, and it can be moved and rotated to suit specific testing needs.
The SolarConstant series is a special design to match the requirements of simulated environmental tests with solar radiation. The spectrum of sunlight (so-called Global Radiation) is accurately reproduced, allowing reliable system performance decisions to be made. The basic components of the SolarConstant systems are the Radiation Unit, the Power Supply and the Control System.
For the Radiation Source, a special metal halide (MHG) lamp is used. The MHG lamp produces a dense multiline spectrum of the rare earths that is comparable to a continuous spectrum. In combination with special glass filters, MHG lamp systems provide a spectral distribution very close to natural sunlight (Total Radiation as defined by CIE 85). Filters with different characteristic are available for applications other than the accelerated aging of materials test. The combination of lamp, reflector and filter, all a part of the Radiation Unit, offers high irradiance efficiency and a superior spatial uniformity.
To achieve the best performance, the lamps are powered using electronic power supplies. The electronic power supply or EPS-Module drives the lamp with square-wave current. This reduces the modulation of the radiation to less than +/-1%, controls the intensity and offers a stabilized power output even when incoming (feed) power varies. In addition, it provides the lamp optimal operation conditions, which results in an extended MHG lamp lifetime.

Full-Scale Bridge Cable Corrosion Chamber

Full-Scale Bridge Cable Corrosion Chamber

The full-scale bridge cable corrosion chamber was custom-designed and manufactured for Columbia University since no product of this scale was commericially available at this time. Although the system was constructed for the purpose of studying corrosion in bridge cables sections, its design was aimed at flexibility, to enable both augmentation and expansion of current research as well as applications in future projects. Just recently, the system was used in research into the effects of fire on main cables for suspension bridges.
The system’s open-ended computerized control system allows for it to expose samples to a wide spectrum of corrosive environments, including salt water rainfall, weak acid rainfall, hot, cold, and dry conditions. The radiant heating, ventilation, and cooling systems allow the system to cycle quickly between environmental conditions. This is the first bridge cable corrosion chamber housing a full-scale panel of a suspension bridge wire rope under axial tension in the world.

PTI Asphalt Pavement Analyzer

PTI Asphalt Pavement Analyzer

The Asphalt Pavement Analyzer Jr. (APA Jr.) is a multifunctional Loaded Wheel Tester (LWT) used for evaluating permanent deformation (rutting), fatigue cracking and moisture susceptibility of both hot and cold asphalt mixes. Testing time for a complete permanent deformation evaluation is 2 hours and 15 minutes (8,000 cycles). The testing time for fatigue cracking evaluation is dependent upon the fatigue behavior of the mix being evaluated.
The APA features controllable wheel load and contact pressure that are representative of actual field conditions. Each sample can be subjected to a different load level resulting in contact pressures up to 200 psi (1378 kpa). Triplicate beam samples, or six cylindrical (gyratory, vibratory, marshall pills, roadway cores) samples in three specially designed sample molds can be tested under controllable temperature and in dry or submerged-in water environments.
Fatigue cracking resistance of asphalt concrete can be determined by subjecting beam samples to a repeated wheel load of controllable magnitude and contact pressure in a low temperature environment. Triplicate beam samples can be tested under dry or submerged-in water environments. The Automated Data Acquisition System features a computer, monitor, and software for measuring rutting and fatigue. The software obtains all measurements and then plots them in a numeric and graphical format. The graphs display stroke vs. deformation (mm) and stroke vs. time.
The APA-Jr. meets the provisions of the AASHTO TP63-06 Test Method for determining the rutting susceptibility of hot mix asphalt. In addition to this, the APA Jr. meets the provisions that are required for the AASHTO T324-04 Test Method for Hamburg-Type Wheel Tracking Test.
The APA-Jr. is operated utilizing a PLC PC Based Control System. The operating system allows a user to perform all calibrations and functions directly with a computer. The APA Jr.’s versatile architecture allows it to also perform custom abrasion, rutting, and fatigue tests on expansive range of materials.
