WebNov 9, 2024 · For a given pavement section and when supported by the available data, three RFPs should be calculated; one based on IRI, one on rut depth, and one on skid resistance. The shortest RFP was assigned to the pavement section in question to flag that section for potential treatment actions. WebNov 17, 2024 · The rutting factor decreases with the increase of temperature, indicating that the higher the temperature, the worse the antirutting ability of asphalt. According to … basecamp poolWebHowever, the air-void ratios for T1-5 and T4-4 are quite low (about 2%). Preliminary rutting tests of T1-5 showed a relatively low rutting resistance. Therefore, the binder content of T1-5 was reduced from 4.4 % to 4.0 %, which increased its air-void ratio from 2.0 % to 4.5 %. As a result, the mixture gained sufficient rutting resistance. swantje nikolai

"WebThe rut depth and dynamic stability were determined by using a wheel tracking test at two various testing temperatures of 45 and 55°C and two applied stresses of 70 and 80 psi. Results show that adding 1% of steel fibres to asphalt mixtures is very effective in increase the rutting resistance and reduce moisture damage. " - Rutting resistance index
