Diesel particles could degrade roads

Different aggressive organic materials could be at the origin of the premature degradation of roads according to a recent Japanese study, including particles emitted by diesel vehicles.

Japanese researchers wanted to understand the causes of as yet unexplained degradation of asphalt and concrete : blisters, cracks, detachment of layers. And according to their study, the premature degradation of roads could partly come from thediesel car exhaust.

The diesel particles involved?

According to this study, the presence of several particles would aggravate the deterioration of concrete and asphalt on roads.

Among them, we find that of car tires. These airborne tire particles associated with those that come from diesel vehicle exhaust could greatly aggravate the phenomenon of deterioration of pavements

Other suspected products

After several batteries of tests carried out by the scientists, the latter made several hypotheses on other products, including washer fluid.

By absorbing atmospheric moisture laden with harmful organic matter, pavements accumulate toxic elements and see their degradation process accelerate.

By seeping into the bitumen, the washer fluid would go dissolve the interlayer, and the asphalt would appear bloated in these areas.
