Stiffness Modulus of Aged Asphalt Mixtures
Solid State Phenomena, 2022Asphalt mixtures have a dominant position in road construction in most countries. The choice of asphalt mixture type and surface depends mainly on the traffic loading and climatic conditions. The stiffness of asphalt mixture is one of important parameters that determines how road pavement performs and what pavement response to traffic loading.

Dynamic Stiffness Modulus for Pavement Subgrade Evaluation
Journal of Transportation Engineering, 2003To avoid cumbersome traditional techniques for pavement subgrade evaluation such as the California bearing ratio and the plate loading test, several nondestructive tests (NDT) as well as suitable analysis processes have been introduced to assess the properties, the structural condition, the residual life, and the possible need for improvement of ...

Stiffness of bi-modulus hexagonal and diamond honeycombs
Journal of Mechanical Science and Technology, 2019Cellular materials are widely used in various applications because of their low density and high strength. The mechanical behavior of cellular materials under various loading conditions has been investigated. Nevertheless, many of these previous studies assume that the Young’s modulus of constituting struts is the same in tension and compression.

Determining of Asphalt Stiffness Modulus
2017This chapter deals with the development of equation that expresses the bitumen stiffness modulus as a function of time, temperature and the simple properties of bitumen such as penetration (or penetration index) and softening temperature. As mathematical model for describing the stiffness of bitumen, Christensen and Anderson (CA) equation was used. The

Asphalt Concrete Stiffness Modulus Estimation Utilizing an Algorithm Approach
Airfield and Highway Pavement 2013, 2013The stiffness modulus is an important factor for asphalt mixture characterization, and multiple procedures and theories have been developed, as shown in international literature, to determine the stiffness moduli. Among these, the dynamic modulus (E*) has played an increasingly important role in recent years, with the E* being introduced as a key ...

Evaluation of the indirect tensile stiffness modulus test
Sixth International RILEM Symposium on Performance Testing and Evaluation of Bituminous Materials, 2003In view to enhance in the field of characterization of asphalt mixes and to develop new test methods, RTE (the central laboratory of SCREG) has acquired a universal testing machine designed to conduct indirect tensile stiffness modulus testing. The interest of this technique is that it is time-saving compared to complex modulus and direct tension ...

Influence of Salt Freezing on Asphalt Mortar's Stiffness Modulus
ICTE 2013, 2013In winter of the northern region, de-icing salt will be used when the pavement is covered with snow. However, the use of de-icing salt will affect the performance of the pavement materials greatly. The stiffness modulus is an important indicator of asphalt mortar's performance. So the stiffness modulus is selected as the research object.

Equivalent Stiffness Modulus of Polyester Fiber Reinforced Asphalt Concrete
Journal of Highway and Transportation Research and Development (English Edition), 2007AbstractThe equations established for fiber reinforced composites by Zhao and Tandon using the theory of micromechanics are used to discuss effective stiffness moduli of fiber reinforced asphalt concrete under low temperature. The results of these equations are compared with experimental data from splitting test under several temperature levels within −

Effect of substrate stiffness on hepatocyte migration and cellular Young's modulus
Journal of Cellular Physiology, 2018Hepatic fibrosis progress accompanied by an unbalanced extracellular matrix (ECM) degradation and deposition leads to an increased tissue stiffness. Hepatocytes interplay with all intrahepatic cell populations inside the liver. However, how hepatocytes migration and cellular Young's modulus influenced by the substrate stiffness are not well understood.
