An automatic generation method for three-dimensional morphology of ruts in asphalt pavements comprises: constructing a standard rut cross-section representation model, classifying ruts, acquiring detection data of a rutted section of an asphalt pavement, selecting different rut cross-sections at equal intervals in a longitudinal direction of the pavement, denoising and smoothening the rut cross-sections, selecting feature points according to geometric fluctuation features of the rut cross-sections, connecting the feature points and fitting a cross-sectional curve based on an evolution law of rut deformation, and fusing multiple reconstructed rut cross-sections to realize automatic generation and visualization of three-dimensional morphology of a rut.

A method for paving a steel bridge deck comprises laying consecutively a 0.6 mm-0.8 mm epoxy waterproofing bond material layer, a 30 mm-40 mm injectable self-flowing asphalt concrete material layer, a 0.4 mm-0.6 mm epoxy asphalt bond material layer, and a 25 mm-40 mm latex cement mortar poured asphalt concrete material layer onto the top of the steel bridge deck to form the steel bridge deck pavement structure.
