This time, experts suggest using high molecular weight polyethylene as an additive to asphalt. It is worth noting that this material really has incredible strength. In this connection, it is used for the manufacture of articular prostheses, body armor and aircraft.
The only problem that, in fact, was solved by domestic chemists, is the complex and expensive process of processing polyethylene into the final product. However, now, thanks to the new catalyst, it has become possible to eliminate the energy-consuming stages of material production and reduce its cost from 2500 to 150 rubles per kilogram.
As for the new asphalt, scientists propose to form reinforcing mesh of high molecular weight polyethylene directly inside the coating. According to preliminary estimates, such a laying technology will be able to triple the life of domestic roads.
In addition, the researchers are confident that the use of such grids will not be limited to “hardening" of asphalt. Based on them, it will be possible to create protective equipment for cyclists and motorcyclists, as well as sails and cables.
