Asphalt Pavement Analyzer

The Florida Department of Transportation is seeking bids for the purchase of an Asphalt Pavement Analyzer (APA) to test the rutting susceptibility of asphalt mixtures. The APA must meet the requirements of the American Association of State Highway and Transportation Officials (AASHTO) test method T 340. The successful bidder will be required to deliver the equipment to the State Materials Office in Gainesville, Florida by December 30, 2025, and provide installation, calibration, and verification of the equipment. The contract will include a warranty for a minimum period of one year. • The APA must be a new generation, three-wheeled, multifunctional loaded wheel tester with a Windows 11 operating system. • The APA must be capable of performing the APA Rutting Test (AASHTO T 340-23) and the Hamburg Wheel Tracking Test (AASHTO T 324-23). • The APA must be capable of testing samples in a dry or submerged-in-water condition. • The APA must be capable of performing high-pressure and high-load rut testing. • The APA must be capable of testing 115 mm x 150 mm and 75 mm x 150 mm gyratory samples. • The APA must be capable of testing up to six specimens per test. • The APA must automatically display the real-time development of rut depths in a numeric and graphical format. • The APA must automatically display the stripping inflection point for the Hamburg Wheel Tracking Test. • The APA must be capable of allowing the user to perform all calibrations, operations, and capture all measurements with a computer-based system. • The APA must be capable of adjusting the speed/rate of loading using a laptop computer. • The APA must include a water pump that continuously circulates water during a test when testing samples in a submerged condition. • The APA must include a temperature measuring system to set and maintain both the chamber temperature for dry samples and the water temperature for submerged samples up to 80°C. • The APA must be capable of capturing a minimum of 11 rut depth measurements across the entire length of the test samples for each pass that is made. • The APA must be capable of displaying the number of passes, rut depth measurement on each wheel, and temperature at each pass in Microsoft Excel. • The APA must be equipped with the ability to automatically stop testing on an individual wheel when a specified rut depth is reached.
