This paper based on non-destructive industrial CT testing technology and VG software to study the effects mechanism of curing temperature on cold. The results showed that: compared to 40℃curing temperature, under 60℃ curing temperature have significant influence the mechanical strength and fine micro void distribution characteristics of Marshall specimen. This paper recommends utilize 40℃ as indoor accelerated curing temperature. ©, 2015, Wuhan University of Technology. All right reserved. Source

To ensure the indoor accelerated curing can better simulate actual curing conditions of emulsified asphalt cold recycled mixture, non-destructive industrial CT scanning tests and macroscopic mechanical test are used to study moisture content, splitting strength, and resilient Modulus transformation rule of emulsified asphalt cold recycled mixture under opened, semi-sealed, sealed three different curing methods, revealed the influence mechanism of curing methods on fine micro voids distribution characteristics of cold recycled mixture. Finally, 40℃ semi-sealed is recommended for the indoor accelerated curing conditions of emulsified asphalt cold recycled mixture. ©, 2015, Wuhan University of Technology. All right reserved. Source
