asphalt pavement structure การใช้

• Study of design parameters of asphalt pavement structure of county road in xiangxi
• Analysis of inverted asphalt pavement structure based on cross - anisotropy
• Test and verification of deflection in asphalt pavement structure with linear track
• As a result , it is an urgent engineering problem to determine load level on asphalt pavements scientificly and to research ultimate state design method of asphalt pavement structures
• And two types of fatigue equations are put forward . according to them the fatigue stress coefficient of lcb for the concrete pavement structure and the structure coefficient of tension strength of lcb for the asphalt pavement structure are developed
• Secondly , the mechanical respond of a typical asphalt pavement structure under heavy load was analyzed according to multilayer system elastic theory and characteristics of heavy loads , and analysis method of ultimate bearing capacity of asphalt pavements was advanced
• During the previous analysis of asphalt pavement structure with cracks , the stress intensity factors were usually calculated approximatively using plane strain model for some limitation . however , the assumptive load of this model is not coincident to the practical load
• In this article , computer simulation of mechanical performance of typical asphalt pavement structure under heavy axle load has been analyzed by means of finite element program abaqus , in order to supply some fundamental information for the asphalt pavement structure with higher bearing capacity designing under the heavy axle load
