Asphalt Of Mandalika Circuit, PP Precision Revealed Materials To Award MURI Record

JAKARTA - PT PP Presisi Tbk (PPRE) ensures that complaints about the conditions across the Mandalika Circuit, Lombok can be immediately resolved. PP Presisi is a subcontractor that works on more than 90 percent of the construction of the Mandalika Circuit.

"We brought in heavy equipment such as asphalt finisher, cold milling, tandem roller, Pneumatic Tire Roller and Millimeter GPS and arrived in Lombok on Sunday, February 20, 2022. Material is planned onsite on February 25–26 2022 and resurfacing plans to start on March 4 2022 with a target of completion on March 10, 2022," said PP Presisi Director of Operations M Darwis Hamzah, in a statement quoted on Thursday, February 24.

In fact, a number of MotoGP riders and teams gave an appreciation of the layout and design of the circuit after the pre-season test passed. They also assess the safety standards, runoff area, gravel on the circuit is adequate.

However, some also complained about the dusty track conditions with small stones on the track. The complaint has been followed up by Dorna and FIM by issuing a recommendation to re-pave at a number of points in the Mandalika Circuit.

"The MotoGP pre-season is actually a means of feedback for us to ensure the readiness and quality of the track before the big event is held," said Darwis.

Darwis also emphasized, to guarantee the quality of the asphalt, PP Presisi uses a type of asphalt that has a high penetration power with Penetration (PG) 82 in 2015, which is not used in all world circuits.

The spreading method is also carried out specifically by using 3 GPS Millimeter units to ensure the right surface quality and slope according to the design which is directly supervised by foreign consultants.

"And for testing the quality of asphalt, we use a high-tech tool, namely PQI 380 Non Distraction without damaging the asphalt surface layer," said Darwis.

As is known, the construction of the Mandalika Circuit has won 3 MURI records, namely; Construction of the Fastest Circuit, Construction of the Federation Internationale de Motocyclisme (FIM) Standard First Circuit; and Asphalt Using Building Information Modeling (BIM) Technology with the highest volume.

The 4.3 km long circuit with 17 bends and a maximum track speed of 310 km / h was designed by MRK1 Consulting according to FIM standards using BIM technology for asphalting. The circuit's main material also has special asphalt specifications, namely Stone Mastic Asphalt (SMA).

This material was only released in 2015 with international standards which is used as a mixture of asphalt to coat the top surface of the asphalt and strengthens the structure of the surface layer of the track so that the racer does not easily slip during rainy conditions.
