Deflection evolution conversion point determination method based on full-scale asphalt pavement life cycle test
The invention relates to a deflection evolution conversion point determination method based on a full-scale asphalt pavement full-life-cycle test, and belongs to the technical field of road engineering.According to the method, on the basis of the full-scale asphalt pavement full-life-cycle test, deflection evolution conversion points are determined according to the correlation between deflection data and equivalent design axle load accumulative action times; a transition point of the asphalt pavement in a service performance damage evolution process in a whole life cycle is found, and when service performance damage decay is about to enter an acceleration period, effective maintenance measures are adopted to improve the pavement use condition, so that the service life of the asphalt pavement can be greatly prolonged, and the service life of the asphalt pavement is prolonged. And the method has important practical significance in improving the durability of the pavement, reducing the use cost in the whole life cycle and the like.
