International motorcycle racing returns to Indonesia with help from Lintec and Linnhoff Asphalt Plants

•  A Lintec CSD3000 asphalt plant supplied more than 50,000 tons of hot mix asphalt from the highest-quality materials for the high-profile project.

•  Premium-technology Stone Mastic Asphalt (SMA) is used for the surface layer of the brand-new 4.31 km track on Lombok Island, making the circuit one of the few to adopt this harder-wearing technology.

•   The Mandalika Circuit will be used as an ordinary road outside of race events.




International motorcycle racing has returned to Indonesia after a 24-year hiatus. A Lintec CSD3000 containerised asphalt plant, the largest mixing plant in the country, has been key to producing its new, premium-quality, racetrack in record time. Two units of Linnhoff TSD1500 MobileMix asphalt plants were also deployed to produce the asphalt mix for the run-off areas.

The construction work on the 4.31 km Pertamina Mandalika International Street Circuit on Lombok Island’s southern coast began in June 2020, as part of the Indonesian government’s campaign to promote new international tourist destinations. Paving works began in February till August 2021, with the entire project completed by October 2021. The circuit was ready to host its first race – the finale of the FIM Superbike World Championship (WorldSBK) season – during November 19-21.


 

Tough surface

As the resort area of Mandalika forges ahead with its multi-billion dollar transformation into a luxury coastal resort worthy of rivalling nearby Bali, the track will become the only street circuit in the prestigious MotoGP calendar functioning as an ordinary road when no events are scheduled.

The surface layer is specially paved using special Stone Mastic Asphalt (SMA) mixture, which combines the famously tough coarse aggregate Tau stone from Palu, Central Sulawesi, with Performance Grade (PG) 82 polymer-modified bitumen (PMB). Also added was limestone filler from Ponorogo and Probolinggo, East Java, and cellulose fiber additives from Germany, only the highest-quality materials were used. By strengthening the structure of the surface layer so that it remains strong through stone-by-stone contact, its high cohesive strength provides greater resistance to intense heat and heavy loads. Additionally, by remaining non-slippery in wet conditions, this mix is especially suitable for racetracks in tropical regions.

With its well-earned reputation for effective screening, accurate weighing, proper and efficient drying, and a production output of up to 240 tons per hour, the Lintec CSD3000 plant was therefore the obvious choice. The high capacity asphalt plant was chosen to minimise the paving joints for a smoother race track surface. With the PG 82 PMB providing improved workability of asphalt mixtures, it was imperative that the contractors used an asphalt mixing plant that could be relied upon to provide homogeneous output to ensure a reliable production capacity of the optimum mix.

It produced a total of over 50,000 tons of hot mix asphalt for the three layers of the main track; namely the Asphalt Concrete (AC) base layer, AC binder layer, and the SMA surface layer.
