Rubber particle-doped composite chip seal and construction method thereof

Abstract

A rubber particle-doped composite chip seal and a construction method thereof. The rubber particle-doped composite chip seal includes a coarse aggregate in a lower layer, a fine aggregate in an upper layer, and an SBS-modified emulsified asphalt binding and encapsulating the coarse aggregate and the fine aggregate into a whole, wherein the coarse aggregate is a gravel having a particle size of 4.75 mm to 7.1 mm, the fine aggregate is rubber particles having a particle size of 1.18 mm to 4.75 mm after pre-treatment, and the fine aggregate has a doping amount of 30% to 45% of a volume of all aggregates.
