Some 1.5 kilometres long part of the Pest-side lower quay is built with the technology of rubber modified bitumen, which is developed and produced based on the patent of MOL. According to nrgreport.hu, with this environmentally friendly procedure that won a number of awards, traffic can be quiter and safer, furthermore, the lifetime of the road can be longer than that of the traditional asphalt roads.
About 400 tonnes of rubber bitumen have been produced for the road construction of some 1.5 kilometres long part of the Pest-side lower quay, which enabled MOL to recycle 9600 used pneumatic tyres in an environmentally friendly way. The basic, the setting and the fretting layers are all made by MOL Rubber Bitumen.
Until now 50 kilometres of roads in altogether 25 road sections have been built in Hungary by using rubber bitumen, which made the environment free from 110 thousand used pneumatic tyres. This amount could cover a normal football field in a 2 metres hight layer.
After the researches and developments lasting for almost a decade, the results of the tests and the experiences on the roads are both very favourable: more permanent, longer life-span, shorter breaking distance and less traffic noise. “Rubber bitumen is an innovative product with which more permanent and economical roads can be built. We are happy that after the road of Budaörs we can contribute to the reconstruction of another important and busy road section of the capital” stated Sándor Fasimon, COO of MOL Hungary.
The chance of the appearance of potholes is far less on the longer-lasting rubber bitumen roads. In addition to lower maintenance costs, traffic safety is bigger as the braking distance is shorter. Traffic noise on the MOL Rubber Bitumen roads lessens, which means 3dB less noise than on a normal bitumen road. In practice, it is like we get double as far from the source of the noise.
MOL’s rubber bitumen developments
MOL has worked together with the University of Pannonia to create this new manufacturing technology that makes bitumen out of used pneumatic tyres. The chemically stabilized MOL Rubber Bitumen was patented in 2009, then won the Hungarian National Ecolabel in 2014. The MOL Rubber Bitumen also received a number of international and national honours in the last few years. It won the Environmental Innovation Award of the Hungarian Ministry of Agriculture in 2014, while last November in Manchester it won the Innovative Product Award of 2016 of IChemE (Institution of Chemical Engineers) in a strong international field.
