This invention relates to the field of road engineering technology, and more particularly to a multi-objective performance coupling design method for warm-mix synchronously recycled SBS modified asphalt. The method determines the aging degree of aged SBS modified asphalt through testing, and accordingly determines the optimal dosage of the two-component synchronous recycling agent and the warm-mix agent. Subsequently, a diffusion model and a fusion degree calculation model for new and old SBS modified asphalt are established to quantitatively analyze the fusion degree of new and old asphalt under different temperatures and aged asphalt dosages. Based on this, a fusion degree spectrum is constructed, and by defining thresholds for each performance index, a feasible design scheme range for balanced performance is obtained, thereby determining the optimal mixing temperature and the maximum dosage of aged SBS modified asphalt. This invention can quickly determine the maximum allowable dosage of aged SBS modified asphalt and its corresponding optimal mixing temperature while considering multiple performance objectives, providing a reliable theoretical basis for the durability design of high-performance recycled SBS modified asphalt pavements.

This invention discloses a method for local heat treatment of unequal thickness structures in large pressure vessels, used for heat treatment of butt welded joints between the cylinder and reinforcing plate. The method includes the following steps: (1) determining the relevant dimensional parameters of the unequal thickness welded joint, including the inner diameter D of the cylinder, the cylinder wall thickness T, and the thickness t of the reinforcing plate. Then, the inner radius R of the cylinder is R = D / 2, the thickness ratio k = t / T, and t > T; (2) determining the local heat treatment heating method; (3) determining the optimal heat treatment process parameters, including the heating band width, holding temperature, holding time, heating rate, and cooling rate; (4) implementing the heat treatment and recording the heat treatment temperature curve. The method provided by this invention can provide optimal heating band width, holding temperature, holding time, heating rate, and cooling rate for local heat treatment of unequal thickness welded joints, effectively reducing inconsistent deformation and uneven stress distribution after local heat treatment of thick and thin plates, and preventing cracking of the unequal thickness welded joint.
