3.1.1.3 What is needed for PA implementation? In this report, the newest PMTP also known as Pave IR technology, Pave IR ScanTM, is considered for implementation in Pennsylvania. This set up is the least invasive, simplest, and most up to date technology. When implementing this technology in a new state, DOTs often began with webinars and construction demonstration projects to teach about the new technology, how it can improve operations, and how to interpret the results [62]. This allows the DOTs and their respective contractors to see the technology in action and have a professional explain and answer any questions. At this point, the DOT can determine if they want to implement the technology in their state. The entire set up costs $30,000 - $35,000 with the bulk of the cost coming from the 36
