Development of time-temperature-humidity superposition principle for asphalt mixtures
Mechanics of Materials, 2021Abstract Variation of the humidity in asphalt layers may very likely induce change in the viscoelastic properties of asphalt mixtures. It has been the authors’ speculation that humidity is an important factor in the properties of asphalt mixtures, just like temperature.

Time-temperature superposition principle for bituminous mixtures
Revue européenne de génie civil, 2009ABSTRACT In the small strain domain (amplitudes below about 10−4), when considering 1D approach, the bituminous mixtures behaviour is linear viscoelastic, with a great thermal sensitivity and respects the Time-Temperature Superposition Principle (TTSP). In this paper, the generalisation of the TTSP is proposed for 3D.

Fractional relaxation and the time-temperature superposition principle
Rheologica Acta, 1994Relaxation processes in complex systems like polymers or other viscoelastic materials can be described by equations containing fractional differential or integral operators. In order to give a physical motivation for fractional order equations, the fractional relaxation is discussed in the framework of statistical mechanics.

Study on the transferability of the time temperature superposition principle to emulsions
International Journal of Cosmetic Science, 2006SynopsisThe instability of emulsions is basically clarified by a phase separation. The separated phase can either cream or sediment. Destabilization is mostly compounded by coalescence and gives a first indication through extension of droplets. In the cosmetics industry as well as many other branches of industry such as the food industry and paint and ...

Time-temperature superposition principle and scaling behaviour
Journal of Materials Science, 1987The time-temperature superposition principle, frequently used to describe the mechanical and electrical relaxation behaviour of polymers, is considered within the more general concept of scaling with translation path parallel to the abscissa. The most general functions leading to scaling with translation path parallel to the horizontal axis are given ...

Research on the time–temperature–damage superposition principle of NEPE propellant [PDF]
Mechanics of Time-Dependent Materials, 2015 To describe the relaxation behavior of NEPE (Nitrate Ester Plasticized Polyether) propellant, we analyzed the equivalent relationships between time, temperature, and damage. We conducted a series of uniaxial tensile tests and employed a cumulative damage model to calculate the damage values for relaxation tests at different strain levels.

Abstract This study aims to validate the applicability of the partial time–temperature superposition principle to simulate the behavior of thermorheologically complex modified asphalts. Six different asphalts were used to analyze this complexity using dynamic mechanical tests within the linear viscoelastic regime.

Application of principle of time-temperature superposition in studying asphalts
Chemistry and Technology of Fuels and Oils, 19761. A method has been developed for application of the WLF principle of time-temperature superposition to describe the viscoelastic characteristics of asphalts. 2. In the example of determining the temperature dependence of undisturbed structure of asphalts, good agreement has been demonstrated between experimental results and values ...

The time–temperature superposition principle (TTSP) is known to be valid in the small strain domain where the behaviour of bituminous mixtures is linear viscoelastic (LVE). The behaviour is then called thermorheologically simple. In this work, an experimental campaign was performed at University of Lyon/ENTPE (France) to check the validity of the TTSP ...

The time-temperature superposition principle (TTSP) was applied to the destabilization kinetics of a pharmaceutical emulsion. The final goal of this study is to predict precisely the emulsion stability after long-term storage from the short-period accelerated test using TTSP.
