very unique to the company Below is a description of each partnership project Real time density mapping Volvo CEs new Density Direct intelligent compaction system which offers the industrys first real time density mapping technology is the result of a decade long partnership with the University of Oklahomas School of Electrical Engineering Volvo has been a fantastic partner not only have they provided insight into the market and equipment but theyve also helped us with filing patents says Dr Sesh Commuri professor at the University of Oklahomas School of Electrical Engineering Thanks to the partnership we were able to develop test and make commercial products that require a lot more capability than what the university has The technology which was unveiled in February at the AGG1 World of Asphalt is an intelligent compaction analyzer that estimates the density of asphalt pavement in real time Within the Density Direct system is a calibration screen where the user sets the asphalt mix information for the project Once fully calibrated with data specific to the application the system produces a density calculation that is accurate to within 15 percent of core sampling Beyond the horizon While the partnership with the University of Oklahoma resulted in an actual product the two research projects with Stanford University and Carnegie Mellon University are future focused exploring emerging possibilities that arent focused on within Volvo CE Normally we at least know the approximate product we are looking for and have some answers to the technical questions Elfsberg says With the Stanford and Carnegie Mellon students we have asked more questions than we have given information Solutions for an urban population For the past three years Volvo CE has partnered with Stanford Universitys Mechanical Engineering Global course Together graduate students in Dr Larry Leifers class work alongside students from a similar course at Swedens Blekinge Institute of Technology to help Volvo CE develop solutions in the area of urban mining a term used to describe a sustainable approach to construction and deconstruction in city landscapes Student engagement with companies is absolutely vital to the delivery of top quality learning experiences Leifer says While faculty deliver the theory companies are able to deliver the practice Stanfords ME310 Global is the Formula 1 version of the prod EQUIPMENT RESEARCH 50 PIT QUARRY July 2015 www pitandquarry com
