Linnhoff asphalt plant achieves progress on Ghana road project

A Linnhoff TSD1500 Mobile Asphalt Plant has achieved remarkable progress on the Grade Separation of the Tema Motorway Interchange in Ghana

The roundabout at the Interchange had been troubling motorists with its severe traffic congestion and so the ‘Project for the Improvement of Ghanaian International Corridors’ was therefore implemented – one of the priority projects proposed in the ‘West Africa Growth Ring Corridor Master Plan’. A US$57mn grant from the Japan International Cooperation Agency (JICA) soon followed in aid of this project.

In February 2018, work on the Tema Motorway Interchange began, transforming the roundabout into an interchange with an underpass, the construction of a 2.1 km three-lane dual carriageway with 730 m underpass on the N1 and improvement of 1.9 km of two-lane dual carriageway on the N2. It also included the paving of five service roads and eight ramps for right-turning traffic, a 190 m-long box-culvert underpass, four disability-friendly pedestrian bridges, traffic signals, street lighting and other safety-critical features.

The Linnhoff TSD1500 MobileMix Asphalt Plant consistently churned out 100-120 tonnes of hot mix asphalt per hour, playing a crucial role in keeping the project on track. Overall, it produced around 52,000 tonnes of hot mix asphalt for the construction of a total of 150,000 sq m of asphalt works, for use in the base, binder and wearing courses.

The plant’s unique dual-function screen drum technology enables both the drying and screening of aggregates to be processed in the same drum, eliminating the need for a hot elevator and vibrating screens. Not only does this reduce fuel consumption and emissions, but maintenance is easier too, reducing costly downtime.

All of the four main mobile modules that make up each Linnhoff TSD MobileMix asphalt batch plant are pre-assembled at the factory, before undergoing rigorous test cycles to ensure smooth set-up once they reach the jobsite. And, being equipped with a hydraulic powerpack self-jacking support system, there is no need to employ large cranes for the installation and dismantling processes, meaning plant operation can begin more quickly.

By offering important advantages in terms of enhanced mobility, the Linnhoff TSD series is ideal for use in remote locations or short-term projects. After the work on Tema Intersection was completed, the plant was moved to the National Trunk Road N8 jobsite.

Teo Siang Leong, general manager of sales at Lintec & Linnhoff Asphalt Pte Ltd, explained, “In Africa, renting cranes can be difficult and expensive, and then finding suitable trucks to transport the individual modules is even more costly. However, each of the four main mobile modules of our Linnhoff TSD MobileMix Asphalt Plants comes with built-in chassis, so they are much easier to mobilise as they can all be quickly dismantled and transported as only prime movers are needed.”
