MAQOLA ANNOTATSIYASI

Ushbu maqolada bitum va asfalt-beton materiallarining ekspluatatsion xususiyatlarini yaxshilashga qaratilgan zamonaviy uslublar tahlil qilinadi. Tadqiqotda bitumning fizik-mexanik va reologik xossalarini oshirish uchun polimer qo‘shimchalar, nanozarrachalar hamda qayta ishlangan materiallardan foydalanish imkoniyatlari o‘rganilgan. Asfalt-beton aralashmalarining mustahkamligi, suvga chidamliligi va yuqori hamda past haroratlarda barqarorligi eksperimental sinovlar asosida baholangan. Natijalar shuni ko‘rsatdiki, modifikatsiyalangan bitum qo‘llanilganda qoplama deformatsiyaga chidamliligi oshadi, yorilish xavfi kamayadi va xizmat muddati uzayadi. Shuningdek, ekologik jihatdan samarali texnologiyalarni qo‘llash orqali ishlab chiqarish xarajatlarini kamaytirish va atrof-muhitga salbiy ta’sirni minimallashtirish mumkinligi aniqlangan. Tadqiqot natijalari yo‘l qurilishida innovatsion materiallardan foydalanish samaradorligini oshirishga xizmat qiladi
