Road of science and technology for a trustworthy project

The PKM (Sukkur-Multan Section) project is a high-standard motorway with the highest design grade. It is also the only motorway in Pakistan with trees along the entire road and can resist once-in-a-century floods. Based on the quality assurance and quality control system, a multi-level and all-round quality control network incorporating design and construction was established to build a most advanced intelligent motorway in Pakistan with innovation and ingenuity.

To adapt to the local high temperatures and heavy workloads, a new anti-rutting technological standard of asphalt pavement mixtures was applied, which can withstand the high temperature of 80 degrees Celsius. SBS modified bitumen was applied to ensure the road formation quality. The UAV aerial photogrammetry technology was used in Pakistan for the first time to obtain accurate data. The hydro-physical model was adopted to optimize the design of cross-river bridges. The difficulty in erecting small skew bridges was successfully overcome. For the first time, the deflection testing technology was applied to control the quality of subgrade and pavement. The standard of intelligent transportation system in Pakistan was improved by the entirely electronic and automatic toll system and signal management. The optical cables laid along the entire motorway can transmit real-time surveillance videos and other information to the control center to have a full control of traffic situations and ensure traffic safety.

Qasir, a Pakistan employee of the project, participated in the project's construction from the very beginning. He said, "I'm fully confident with its quality. This motorway we built is a trustworthy quality project. When the employer was carrying out testing for acceptance along the motorway, the testing team unanimously appraised the PKM project as the fastest motorway project of the best quality in Pakistan."
