Conversely, PEMs have quite low bearing properties, clogging, variation of volumetrics over the time, variation of noise, texture, friction, and permeability performance over the time.
It’s important to emphasize that PEM properties vary over the time.
International literature on the use of the RAP in wearing courses remarks two key-factors which can affect the derivation of the optimal amount of RAP to add: the mineralogical selection of the RAP aggregates and the extraction technique of the RAP.
The mechanical properties of the recycled mixes were assessed in terms of Marshall stability (UNI EN 12697-34) and Brazilian test (UNI EN 12697-23) (Figure 7 and 8).

Shallow sand was used as soil [11], the properties of which are shown in Table 1.
Soil-cement, 10 % of pigment 0.89 Mathematical experiment planning To obtain the adequate mathematical model of the impact of mixture components (factors) on the mechanical properties of soil-cement it was planned to carry out the experiments based on mathematical model shown in Table 5 (orthogonal central composite plan OCCP).
The difference between the degrees of factors influence on the grade under split is about 2-times.

In this paper, two main influence factors of the movement, BHF and the blank thickness at the both sides of the weld-line, were studied by both the experiments and finite element simulation.
The laser welding technology is used to join some blanks with different thickness and material properties into the TWB.
So the thickness ratio is also an important influence factor to the weld-line movement

These factors can lead to deterioration and detachment or reduce the mechanical properties of the substrate.
The mechanical properties of the fabric were obtained through tensile tests on three specimens having 500 mm length and 50 mm width.
Physical and mechanical properties of the textiles are summarized in Table 1.

The strain relationship between them is projective corresponding to each other, and is affected by the material properties.
Recent papers show that there are several factors which lead to the formability decrease of TWB.
Efforts have also been paid to improve TWB formability which focuses on the factors such as welding technologies, the thickness of parent metals as well as stress differences [7, 8].
Our previous work have shown that the integrated strength, which is affected by material properties and thicknesses, is a main factor to degrade the formability of TWB, and the discrepancy of integrated strengths on base metals can affect both cracking trend and cracking type.
Material properties used in the model are listed in Table 1.

The reduction in mechanical strength of rubberized concrete is commonly attributed to three primary factors.
Other factors, including the viscosity of the concrete mix, mixing methods, and fiber volume fraction (FVF), also influence the degree of fiber distribution.
Additionally, the distinct chemical nature of CR compared to conventional aggregates results in poor adhesion with the cement paste, negatively affecting the development of mechanical strength.
The indices Ni and Nf were thus earmarked as the initial and final crack resistance factors, respectively.

Corrosion resistance is an important property that could be affected by the ageing process.
This change in the microstructure can significantly affect the mechanical properties of the alloys.
The implication of the results is that both yield strength and corrosion resistance are controlled by the same microstructural factors.
Combined influence Therefore, there are two contradictory tendencies affecting the corrosion resistance during ageing.

Shell is a natural composite material with excellent mechanical property. it is a model of biomimetic composites.
A great deal of attention has been paid to its excellent mechanical properties by material scientists [4-8].
Different layers of shell have different structure, so mechanical properties are anisotropy.
In addition, the lathy fibre cluster in the middle layer, staggered arrangement of angle-shaped fibre cluster in inner layer and its laying angle are key factors to increase compression and impact of the scallop shell, thus the destroy of the scallop shell is small.
The rectangular fibre cluster in the middle layer, staggered arrangement of angle-shaped fibre cluster in inner layer and its laying angle are key factors to increase compression and impact of the scallop shell, thus the destroy of the scallop shell is small.

Understanding how hierarchy affects their mechanical properties emerges as a primary concern, since it can guide the synthesis of new materials to be tailored for specific applications.
Understanding how these structures are related to their mechanical properties emerges, hence, as a primary concern, since it may provide guidance on the development of novel materials with unique properties [5].
Size effects on apparent mechanical properties due to the fractal nature of material microstructure have been extensively studied [7,8] (see also [9]).
The values of the material properties at each level hence depend on those of the preceding levels.
This model is based on the simplifying hypothesis of identical matrix properties at each scale level (Eq. 3).

In the in vivo system, the formation of new blood vessels depends on the properties fibrin gel extracellular matrix.
Different concentration of fibrinogen and thrombin also affect the microstructure of the fibrin gel.
The variation of these properties will be then manipulated to be used for in vitro angiogenesis.
In this context, fibrin matrix has been widely used for the investigation of angiogenic factors involving in ECs differentiation with and without growth factors [4,5].
