Marshall tests were carried out to evaluate the effect of different modifiers on the property of these asphalt paving mixtures.
These results indicate that NMMT/SBS as a composite modifier can result in excellent properties for asphalt paving mixture.
The resulting composite materials exhibit enhancements in thermal, mechanical, and functional properties [3,4].
The performance enhancement derives of some factors.
On the other hand, in the asphalt paving mixture, nano-scale particles can improve the interfacial properties and affinity between asphalt and aggregate, which can effectively restrain water to penetrate and enhance moisture susceptibility.

The rotational speed, load and temperature are main influence factors of the wear of 45 steel.
Introduction As a high elastic material, rubber has some unique properties (abrasion resistance, oil resistance, etc.) that generally metal and other polymer metal have not.
The wear behavior of NBR to metal is influenced by multi factors, and the effect of each factor cannot be described by accurate mathematical language.
The influence of wear factors is very much.
Prediction model can only consider the main factors of the wear and not considered the interaction between various factors.

Formation and performance of the main factors that affect the weld line are material properties, process parameters and die structure.
If the two strands meet melt flow front temperature difference is less than 10 ° C, then melt fusion well, almost does not affect the mechanical properties of the weld line; flow wave front greater the pressure, the more favorable melt fusion, thereby enhancing the welding the strength of the line parts [2]; confluence angle greater than 135 ° is called the fusion line, less than 135 ° is called the weld line [5], convergence angle increases, indicating that the better the performance of the weld line of work pieces appearance and The mechanical properties of the smaller.
In actual forming some weld lines led to products mechanical properties decreased significantly, while others have little effect [4].
Taguchi experimental design method is the use of the orthogonal matrix optimization of multiple experimental factors, by a small number of experiments to identify the factors and the corresponding level under the conditions used in the optimal level combination and experimental factors experimental indicators. 3. 1 To determine the evaluation index and the design variables.

It is one of the most important engineering properties of soil for design of sub grade of roads.
CBR value of soil may depends on many factors like maximum dry density (MDD), optimum moisture content (OMC), liquid limit (LL), plastic limit (PL), plasticity index (PI), type of soil, permeability of soil etc.
Methodology Initially we collected soil samples from the study area and quantified the soil properties.
So it is evident that the geogrids are the best suitable material for enhancing the soil properties of the red soil.
Lime can also be used in partial enhancement of the soil properties.

Incorporating biomolecules such as growth factors in fibers is becoming common for enhancing the biological performance of electrospun scaffolds.
Solvent properties such as conductivity and volatility affected fiber morphology and diameter.
Controlling polymer solution properties and electrospinning parameters, the fiber diameter can be varied from several micrometers to a few hundred nanometers or even smaller [8].
The one-factor-at-a-time (OFAT) method was used for studying the effects of electrospinning parameters on fiber characteristics.
Many factors affected the morphology, diameter and structure of electrospun fibers, including solvent for polymer solution, polymer concentration, amount of the water phase in emulsion, applied voltage, solution feeding rate, etc.
