Research on Hump of Asphalt Mixture Pavement by Accelerating Loading Facility

To research humps of asphalt mixtures and proportions of hump under the conditions of different types of mixtures,temperatures and loads,we carried out Accelerated Loading Test on AC-Type asphalt mixture pavement.The results shows that it has little difference to evaluate humps between depth and area of rut deformation;high temperature will lead to a rapid expanding of humps;deformation of hump is affected by temperature remarkably with different loads;hump proportion only depends on total deformation of rut and the ultimate value of is 0.6.
