With the anti-snow and anti-ice asphalt (mix) pavings, you will obtain more ecologic respect, a lower pollution of the water-bearing strata by sodium chloride, a ower pollution by volatile organic substances, and a higher dissipation of polluting substances.


    The first check of the ECOLOGIC aspect of the asphalt (mix) treated with anti-snow / anti-ice programme can already be made when laying. In this phase, there is a considerable reduction of the emissions of volatile organic substances, that are usually spread into the atmosphere during this type of operation.

    The first ones to take advantage of this will be the people in charge of the laying of the asphalt (mix) and the inhabitants who are near the area where the asphalting is taking place (consider for instance the town centres).

    In addition to this first advantage, that is easy to check, both empirically and instrumentally, there is also a In addition to this first advantage, that is easy to check, both empirically and instrumentally, there is also a asphalt (mix). This feature involves more difficult checks, that are possible only by instrumental surveys, whose results should be carefully compared with other ones, gathered on ordinary asphalt (mix)s, but placed in similar situations.

    Those who benefit from such second ECOLOGICA features of the asphalt (mix) treated with the anti-snow / anti-ice programme,are certainly the users travelling on vehicles, the pedestrians and, of course, the inhabitants living along the territory where there are those pavings.

    A lower emission of volatile organic substances issued by the ecologic asphalt (mix) treated with the anti-snow / anti-ice programme is noticed even when, after several years (at least twice those of a normal asphalt (mix)) you think you have to remove the paving by milling, because it is considered "old" by that time. Even in this case, you can notice a considerable reduction of volatile organic substances released into the atmosphere. Once again, those who benefit from this will be the workmen, the inhabitants living close to the area where the work is carried out, the users and, of course, as in the previous situations, the environment.

    A special attention should be paid to the mere indication of "volatile organic substances released into the atmosphere". Such substances are considered by some researchers as not dangerous for the human health, whereas other experts, equally as respectable, say the opposite. In case of doubt, a considerable reduction of emissions from the pavings made with the ecologic asphalt (mix) treated with the anti-snow / anti-ice programme, should be more than satisfactory anyway.

    Another ecologic aspect of the pavings made with the ecologic asphalt (mix) reated with the anti-snow / anti-ice programme consists in the capacity to dissipate the polluting emissions released during the combustions in general, including those of motor vehicles. It is not just a conversion of the substances that settle on the ground, but of the volatile substances found in the atmosphere.

    Even in regard to this feature, the higher are the thicknesses of ecologic asphalt (mix) treated with the anti-snow / anti-ice programme laid on the ground, the better will be the results.

    This ecologic value is not easy to check instrumentally. It is a matter of measuring the differences in the level of atmosphere pollution, even ten or twenty meters higher than the level of road paving. his type of check may seem relatively easy, since it is already practiced a lot. However, difficulties come out when you want to compare the results found on the pavings made with ecologic asphalt (mix) with the anti-snow / anti-ice programme, compared to those obtained with ordinary asphalt (mix), on equal polluting and atmospheric conditions, including draughts.

    One of the possible points where there can be excellent conditions that also allow appropriate comparisons is the check of the asphalt (mix) laid inside tunnels. In such places, it is possible to limit, at least partially, the variable of the draughts.

    Of course, there must be a historic collection of data about the pollution of such places, made when the paving was with ordinary asphalt (mix) and with a careful traffic monitoring. After the pavings made with the ecologic asphalt (mix) treated with the anti-snow / anti-ice programme, have been laid in the same tunnels, you wait for at least one year before beginning checks on polluting values, that should be repeated several times a year, for at least seven years.

    Last, but not least, there is a fifth ecologic aspect of the pavings made with the ecologic asphalt (mix) treated with the anti-snow / anti-ice programme.

    It consists in the fact that this type of paving does not need to be strewn with salt even during heavy and/or continuous frost, obviously as long as the thicknesses to be laid are complied with, as well as the higher rest times possible of the bitumen (asphalt) containing the programme.

    However, even in case of laying limited thicknesses of ecologic asphalt (mix) (that is, lower than the prescribed ones), even if you do not completely eliminate the salt-spreading operations, they will definitely be reduced a lot.

    As a natural consequence, it ensues that the pollution caused by dispersion of sodium chloride on the ground will be eliminated and/or reduced. More precisely, there is a reduction of the pollution, always by sodium chloride, of the grounds neighbouring the pavings, the surface water flowing on such grounds after snowfalls or rainfalls, that is of brooks, streams and rivers, therefore of the water-bearing strata below, too.

    It is a type of pollution that, if not interrupted as soon as possible, might involve, in the first place, situations of irreversible damage for agriculture and zootechnics, as well as fresh-water fishing, and afterwards even a damage to the people’s health. In this case, it should be in the interest of the agricultural world first, then in that of the sanitary world, to consider the advantages involved by laying pavings made with the ecologic asphalt (mix) treated with the anti-snow and anti-ice programme.

    The ecologic advantages described so far clearly highlight how much an asphalt (mix) with such features, different from the normal pavings, should deserve the evaluation attention of every person responsible for the quality choices of the types of asphalt (mix) to be used.

    Such choices could be considered unavoidable, both in case of private and public pavings, therefore of evaluation interest from designers, contractors, and even public administrators, as long as they have their own health at heart, besides that of all the people, the environment and, therefore, the planet.

    Such interest should also be independent from the primary features of the ecologic asphalt (mix) treated with our programme, that is anti-snow and anti-ice properties. As a matter of fact, among the secondary performance of this programme for anti-snow / anti-ice asphalt (mix) there is also the fact of a having a softening point shifted toward the high level of the temperatures. Therefore, we will have an asphalt (mix) capable of resisting to deformations in case of high temperatures, in a definitely better way than an ordinary type of asphalt (mix).

    It ensues that this ecologic asphalt (mix) containing the anti-snow / anti-ice programme is not only suitable for being laid in areas at risk of snowfalls or frost, but can also be used in territories notoriously hot because of its secondary features, especially the ecologic ones, besides those of resistance and softening.
