Study on the Low-Temperature Cracking Characteristics of Warm-Mix Steel Slag and Rubber Powder–Modified Asphalt Mixtures Using Acoustic Emission Technology

Abstract

AbstractBased on the acoustic emission (AE) dynamic nondestructive testing technology, a semicircular bending test (SCB) was conducted on warm-mix steel slag rubber powder modified asphalt mixture (CR-WSAM) at −10°C and −20°C to monitor its crack evolution behavior ...Practical ApplicationsThe study provides the following significant practical implications: (1) engineering guidance for anticracking design in cold regions, demonstrating that the surface texture of steel slag aggregates and the SDYK warm-mix agent can ...
