Abstract: 
Досліджено можливість використання гу¬мату калію як інгібітора технологічного старіння окисненого нафтового бітуму. Для порівняння відібрано зразки гумату калію, що одержували з різної сировини, зокрема торфу та леонардиту. Проведено розрахунок коефіцієнтів старіння та досліджено експлуатаційні властивості модифікованого бі¬туму як в’яжучого матеріалу для гарячих асфальтобетонних сумішей. Встановлено, що додавання до окисненого нафтового бітуму 3.0 % мас. PH-3 дозволяє сповільнювати процеси тех¬нологічного старіння та одержувати асфальтове покриття із кращими характеристиками в порівнянні з покриттям, виго¬товленим на основі немодифікованого бітуму.
