The invention provides a matching method for a mixture mix ratio at a regenerative microcapsule position based on torsional shear test. The invention belongs to the technical field of road maintenance engineering technology, and particularly relates to a matching method for the mixture mix ratio at the regenerative microcapsule position based on the torsional shear test. The method comprises the following steps of 1, screening over-particle-diameter particles in RAP according to the type of the selected microcapsule position; 2, determining mineral aggregate gradation and cold asphalt content of the RAP material; 3, determining the proportions of the RAP material and new aggregate according to the target gradation at the selected microcapsule position, RAP material mineral aggregate gradation and an old material mixing ratio; 4, selecting modified emulsified bitumen in an optimizing manner; 5, testing workability; 6, determining an oil amount range; 7, defining an optimal asphalt amount; and determining the mix ratio of the mixture at the regenerative microcapsule position. According to the matching method, the RAP material can be reasonably utilized at the regenerative microcapsule position for obtaining the mixture with excellent pavement performance at the regenerative microcapsule position, and therefore the matching method has high popularization value.
