SERDANG, Aug 15 -After nearly a year, UPM has used Fiber Mastic Asphalt Technology (FMA) to increase the durability and road life of 400 meters across the Lebuh Silikon road in UPM campus. The paved road in September 2016, is now still in good condition and satisfying consumers.
Under this technology, the fibers are processed from biomass materials such as oil palm fronds which are added to the mixture of asphalt (tar) to improve the strength and durability of pavements.
It also increases the good bond and seal between coarse aggregate and the bitumen.
Head of the research group, Prof. Dr. M.Ratnasamy said one main issue affecting the roads in the country was damages caused to the roads such as pavement cracks and potholes that took place more often than not, causing the roads to be unsafe and prone to accidents.
According to him, this happened mainly because of the present resurfacing technology which was unable to accommodate to the growing number of passenger and commercial vehicles as well as high traffic density.
This called for road maintenance to be carried out regularly, he said.
Prof. Dr. Ratnasamy who is a lecturer at UPM Department of Civil Engineering, Faculty of Engineering, said the research team he led, concluded that stronger and durable materials should be used to build roads.
"FMA is created to resolve the issues of durability and longevity of roads. The pavement thickness can also be reduced.
"The differences between the roads built using this technology from those constructed the conventional way lie in terms of the additional materials used, size of coarse aggregate and thickness of the road surface,” he said.
He also said the higher percentage of coarse aggregate of larger size (gross) used in road-building compared to conventional asphalt, will make the roads last longer.
"The cost of road construction using FMA technology is the same as the conventional construction but FMA technology is different in that the pavement is of high quality and durable, hence, it helps to reduce the cost of road maintenance.
"This technology can reduce sound frictions, and with thinner pavement and low level of derailment, it makes the roads safer for all vehicles for that aesthetic value of the highways,” he added.
This resurfacing technology was used in the construction of a 400-meter route in Lebuh Silikon within UPM campus, serving as the first test bed for the country to demonstrate its effectiveness. It was launched by UPM Deputy Vice-Chancellor (Research and Innovation), Prof. Dato Dr. Mohd Azmi Mohd Lila.
The technological research started in 1996 and was completed in 2001. It was first commercialized in 2012 through a licensing right granted to Syarikat Novapave Sdn Bhd.
Chief Executive Officer of Novapave Sdn Bhd, Fareez Fahmi said the technology will be used to build village roads in Kampung Cheng, Melaka, in January next year. – UPM
