Abstract: To explore the mechanical response of asphalt pavement structure under vehicle loads in the early period of highway open traffic, firstly, the road performance parameters of pavement material in 7, 14, 21, 28, 35d at 10 ℃ and 20 ℃were gained through laboratory experiments. Then the variation rule of vertical displacement, compressive strain and tensile stress under factors, such as age, axle load and temperature was calculated out by utilizing KENPAVE program. The correctness of the calculation results was verified by actual detection.
