Its mechanical strength is equal to the strength of its adjacent atom.
Asphalt mixtures’ water stability depends on the prosperities of aggregates, the interaction between asphalt and aggregates, and the types of asphalt mixtures, construction, rolling and other factors.
Obviously, calcium sulfate whisker improves the interfacial properties between asphalt and aggregates; increase the viscosity of asphalt mortar; so it can easily improve the water stability of the mixture.
Anti-Fatigue Properties.
Summary 1) As a kind of crystal fiber, calcium sulfate whisker and its mechanism of modified asphalt mixtures are consistent with the mechanism of fiber-reinforced modified asphalt. 2) Test proves that the high-modulus asphalt mixture with the added calcium sulfate whisker modifier can significantly improve its stability in high temperature, water stability and anti-fatigue properties while not affecting its performance in low temperature, so as to solve the common problems on the road, such as rutting, water damage and others and to ensure that the road has a good service performance. 3) The high-modulus asphalt mixture with the added calcium sulfate whisker can not only improve the road performance, but also has significant economical and social benefits.

In order to explore the elasto-plastic properties of PZs, tests of different types of beam-column connections under monotonic loads were conducted firstly.
Focus of tests is to explore the influence factors on elasto-plastic properties of PZs.
And the strengthening factor can be assumed 4/3 according to China specification JGJ99:98.
First, employing the traditional mechanical method and not considering deformation of PZs (that is assuming the PZs is rigid), to calculate the frame story drift angle θ0j, j=1, … , m, where m is the floor number. 2.

The stresses ahead of the lth crack tip are given by π π σ 2 2 )0,( 1 1 111 l l I l l l I l x bT x k x ++= , ππ σ 22 )0,( 1 1 122 l l Il l I l x b x k x += , π π σ 2 2 )0,( 1 1 112 l l IIl l II l x b x k x += , (1) where lIk and lIIk are the stress intensity factors (SIFs). lT , lIb and lIIb are the included higher order stress field parameters.
Incremental step of crack path simulation It is seen, that the curvature of each crack path is affected by the other growing cracks.
(8) The accurate simulation of crack growth is highly dependent upon the accuracy of the calculated stress intensity factors.
The material has only small differences in the tensile properties in the directions longitudinal (Rp0.2 = 286Mpa) and transverse (Rp0.2 = 274Mpa) to the rolling direction.
This affects the stress field at the crack tip and thus the crack path.

To date, many investigations have focused on the microstructure and mechanical property of ultrafine-grained materials subjected to ECAP, however, the study on corrosion property is relatively rare.
The study on corrosion resistance of ECAP-processed materials is complex and challenging, because the corrosion resistance will be affected by many factors induced by ECAP, including grain size alteration, changes in dislocation density, increased grain boundary density, particle fragmentation, residual stress, development of texture, as well as different electrolytes [23].
By increasing ECAP passes and annealing, above-mentioned factors will change, thus the corrosion resistance of materials will be affected.
In that way, grain size is an important factor for improving corrosion resistance.

These nanostructures offer a greater flexibility for the surface functionalization as well as more flexible mechanical properties.
Unlike the widely used CNT, the properties of BNNT are independent of its diameter [5].
Such properties together with the excellent mechanical property and thermal conductivity make BNNT a potential candidate for biosensing applications [7, 8].

Moreover, they are able to increase the overall strength of the injected elements without affecting further mechanical parameters, such as elastic modulus and stiffness, that is often the case of the cement-based ones.
This paper investigates the stiffness variation of injected structures, widening the results and the considerations previously obtained in terms of frequencies, mode shapes and damping factors.
A preliminary dynamic identification, involving frequencies, mode shapes and damping factors could be performed (Mazzon et al. 2008).
Firstly, the starting dynamic behaviour is only limited affected by the injection of this type of admixture.
