Abstract EN
The experiments on the structural mechanics of asphalt pavement were carried out by the digital speckle correlation method (DSCM).
The digital speckle correlation method is used to collect experimental data.
The displacement and strain values of each layer of the asphalt pavement structure are analyzed.
The research showed that (1) the digital speckle correlation methods could accurately observe the displacement value and the strain value of the pavement structure.
(2) The stress state of the pavement structure was greatly influenced by the interlayer effect.
The vertical displacement changed suddenly between layers.
The concentration phenomenon of the tension-compression strain and the shear strain appeared between layers.
(3) The overloading situation seriously worsened the overall stress state of the pavement structure, especially at the bottom of the asphalt top layer and lower layer and at the top of the cement-stabilized crushed stone.
The research results are of great significance to the structural design of heavy-duty roads.
