Rutting simulation and rutting depth prediction of asphalt pavement based on infinite element theory

Permanent deformation of asphalt pavement is the most serious type of premature damages of asphalt pavement.So it is necessary to predict rutting depth accurately and rapidly for pavement structure design and maintains management.The paper put forwards rutting simulation and rutting depth prediction based on definite element method.According to Langfang section pavement design of Langcang expressway,rutting depth prediction of SBS modified asphalt concrete and high modulus asphalt concrete is analyzed using this method.Through analysis,the rutting depth prediction method expressway lane translation method is strict in theory,clear in design procedure and simple in operation.It has important theoretical and practical value,which is a good way for expressway pavement design and maintains management.
