Lintec’s CSM4000 containerised asphalt plants were used in the construction of Pakistan’s Peshawar-Karachi Motorway (PKM)
Lintec CSM containerised asphalt mixing plants have played a major role in helping to improve local transport conditions by opening up central Pakistan’s north-south traffic arteries in the Peshawar-Karachi Motorway (PKM) in Pakistan. Lintec & Linnhoff China sold two Lintec CSM4000 containerised asphalt mixing plants to established customer PowerChina Group Co. Ltd, to support the construction of the 392 km M-5 section. This is the country’s longest motorway, which connects Sukkur, in Sindh Province, and Multan, in Punjab.
The asphalt mixing plants were installed in December 2017 and March 2018, with the first providing 34.1 km of new asphalt road, and the second covering a stretch of 29 km, with three lanes in either direction. Both plants produced over 600,000 tons of hot mix asphalt by the time the project was completed in November 2019, 13 days ahead of the 36-month schedule.
During the construction of this large-scale project, there was a lot of demand on the rapid assembly and disassembly capabilities of the asphalt mixing plants, as well as their mobility. These challenges proved no problem, as Lintec’s CSM range offers clear advantages, with its 100% ISO shipping container design facilitating easier, and economical transport and removing the need for concrete foundations. The pre-assembled modular construction also speeds up assembly.
Two Lintec CSM4000 plants produced over 600,000 tons of hot mix asphalt for the longest motorway project which connects Sukkur, in Sindh Province, and Multan, in Punjab.
“We had already purchased several Lintec asphalt mixing plants, including the CSM and CSD models, for other international aid projects since 2010, so we knew we could easily achieve a fast set-up time,” said Mr Chen, Project Manager at PowerChina. “But just as important was knowing we could depend on the reliable performance and smooth operation because these were challenging conditions, with the local temperature passing 40°C, which can damage some equipment. In order to adapt to the local high-temperature environment, the project adopted a new standard of rutting resistance technology for road asphalt mix at 80 degrees Celsius. Due to the high batching accuracy of the Lintec CSM4000 asphalt mixing plants, this recipe was smoothly implemented, ensuring excellent quality of the road surface.”
To adapt to the extreme environment and heavy workloads, the project adopted a new standard of rutting resistance asphalt for the road surface, capable of withstanding high temperatures up to 80°C. Due to the high batching accuracy of the CSM4000 AMPs, this recipe could be smoothly implemented, ensuring consistently high quality for the surface and providing resistance against even extreme floods.
“As a state-owned enterprise working on an international aid project, our client places the greatest importance on the production safety and stability of its equipment,” said Tony Liu, CEO of Lintec & Linnhoff China. “Lintec’s reputation as a leading brand of German heritage gained widespread recognition and a reputation for safe operation, batching accuracy and mobility performance. This is why we are an ever-present partner in projects under China’s Belt and Road Initiative.”
The complete 1,152 km, US$2.889 billion PKM expressway originates in Karachi, passes through Lahore, and terminates at Peshawar in the north-west province of KPK. As the China-Pakistan Economic Corridor’s largest transportation infrastructure project to date it is speeding up access to China’s western border.
