The main objective of this study was to test both intrusive and non-intrusive data collection devices and to provide North Dakota Department of Transportation (NDDOT) with insight into the accuracy of the various data collection technologies and the applicability of the tested devices. All devices were...

In this study, the researchers evaluated the performance of asphalt mixes prepared using the Marshall mix design method and the Superpave level one mix design method. The Georgia Loaded Wheel Tester and the Thermal Stress Restrained Specimen Tester were used to test the rut-resistance and low-temperature...

In this research the feasibility of using the Georgia Loaded-Wheel Tester (GLWT) to predict rutting in the laboratory was investigated. The study consisted of modifying the GLWT to handle 15.2 cm (6-in.) cores, obtaining asphalt pavement cores from several test sites throughout Wyoming, collecting rut...

This project included two laboratory studies and analytical work dealing with T-beams comprised of a concrete flange connected to a wood beam plus plywood sheathing. Based on the experimental results of tests of 72 slip specimens and 4 full-scale layered T-beams, the mechanical behavior of different...
