Ushbu maqolada avtomobillar harakatlanishi natijasida tormoz ustquymalari va shinalar yeyilishidan chiqadigan zararli zarralarning miqdorini aniqlashda respublika va xorijiy tadqiqotlar natijalari, gʻildirakning yoʻl bilan ilashish koeffitsiyentiga bogʻliq izlanishlar tahlili keltirilgan. Hisob-kitoblarni amalga oshirishda ma’lum bir hududdagi transport vositalarining sonini hisobga olish kerak. Avtomobillar harakatlanishi jarayonida tormoz ustquymalari va shinalar yeyilishi natijasida atrof-muhitga chiqadigan zarralar miqdorini gʻildirakning yoʻl bilan ilashish koeffitsiyentini hisobga olgan holda aniqlash usullari bayon qilingan. Avtomobillarning tormoz ustquymalari va shinalarning resurs davri gʻildirakning yoʻl bilan ilashish koeffitsiyentiga bogʻliq holatda oʻzgarishi inobatga olinib, ularning atmosferaga chiqaradigan zarralari miqdori nazariy jihatdan hisoblangan. Maqolada keltirilgan hisob-kitoblar Jizzax viloyati misolida amalga oshirilgan. Yoʻl chorrahalarida avtomobil tormoz ustquymalari va shinalar yeyilishi natijasida atrof-muhitga chiqadigan zarralar taqsimlanishini IGEO indeksi boʻyicha aniqlash orqali ularni kamaytirish choralari ishlab chiqilgan. Avtomobil yo‘llari uchun asfalt-beton qoplamali yo‘llarni yo‘l qoplamasi modifikatori sifatida ishlatilgan shinalar kauchukining granulalaridan foydalangan holda qurish tavsiya etiladi. Bu esa tirbandlik yuqori bo‘lgan chorrahalarda g‘ildiraklar yo‘l bilan aloqa qilganda, tortishish koeffitsiyentini oshiradi.

В данной статье приведены результаты анализа отечественных и зарубежных исследований по определению количества вредных частиц, выделяющихся из-за износа тормозных колодок и шин в результате эксплуатации транспортного средства, связанных с коэффициентом сцепления колеса с дорогой. При проведении расчётов необходимо учитывать количество транспортных средств на определённом участке дороги. Представлены методы определения количества частиц, выбрасываемых в окружающую среду в результате износа тормозных колодок и шин при движении автомобилей с учётом коэффициента сцепления колеса с дорогой. Учитывая тот факт, что срок службы автомобильных тормозных колодок и шин изменяется в зависимости от коэффициента сцепления колеса с дорогой, теоретически рассчитано количество частиц, которые выбрасываются в атмосферу. Расчёты, представленные в статье, проведены на примере Джизакской области. Предложены меры по снижению распределения частиц, выбрасываемых в окружающую среду в результате износа тормозных колодок и шин автомобилей на перекрёстках, определённого по индексу IGEO. Рекомендуется строить автомобильные дороги с асфальтобетонным покрытием с использованием в качестве модификатора гранул отработанной шинной резины с целью повышения коэффициента сцепления колёс с дорогой на перекрёстках с повышенной проходимостью.
This article presents the results of analysis of domestic and foreign researchs to determine the amount of harmful particles emitted due to the wear of brake pads and tires as a result of vehicle operation, related to the coefficient of grip of the wheel with the road. When making calculations, it is necessary to take into account the number of vehicles on a certain road section. Methods for determining the amount of particles emitted into the environment as a result of brake pad and tire wear during vehicle operation, taking into account the coefficient of grip of the wheel with the road, are presented. Considering the fact that the service life of automotive brake pads and tires varies depending on the coefficient of grip of the wheel with the road, the amount of particles that are emitted into the atmosphere is theoretically calculated. The calculations presented in the article were carried out on the example of Jizzakh region. Measures to reduce the distribution of particles emitted into the environment as a result of wear of brake pads and tires of cars at intersections, determined by the IGEO index, are proposed. It is recommended to build highways with asphalt concrete pavement using spent tire rubber granules as a modifier in order to increase the coefficient of grip of wheels with the road at intersections with increased passability.
