Introduction The asphalt pavement design method based on elastic layered system reflects the mechanical response of pavement structure to some extent, but due to the complexity and variability of materials’ composition and nature, the impact randomness of environment and load factors, and the quality instability of non-factory construction, it is very difficult for the purely mechanical method to learn the real response of actual pavement structure.
On the other hand, although the long-term performance observation could systematically summarize the performance development in the entire life cycle, it is really a long process which costs lots of manpower, material and financial resources as well as analysis difficulty with many influencing factors.
Zejiao Dong (2009)[8] analyzed influence factors of pavement strain response, and space distribution and schedule variation of three dimensional strains.
In consideration of the affecting factors of axle load conversion, temperature correction, transverse distribution and action time respectively, the corrected action times of the first test part is calculated as follows: Ne=10/3×5.83×120×104=2.332×107 times ∈ (1.2×107, 2.5×107), which belongs to heavy traffic based on design specification.
With no load, it is in a steady mechanical phase.

Friction stirring typically induces microstructural changes and grain refinement, affecting the processed material's constitutive response.
In terms of mechanical properties, FSW can result in desirable microstructures as it can produce refined equiaxed recrystallized grains, and it allows for controlling the residual stresses during the welding process [4], [7].
However, the effect of friction stir on materials' high-strain-rate properties remains insufficiently characterized or understood, though it might be significant.
Several factors may contribute to this observation.

By different laser cladding parameters on the microstructure and mechanical properties under the comparative analysis, to make a more detailed discussion of laser cladding power and scanning speed on the quality of laser cladding.
The aim is to improve the wear resistance of the surface heat corrosion resistance and other properties, so their quality cladding layer is crucial, which requires the quality of cladding layer at the macro and micro organization has a better Indicators, which will affect the quality of cladding layer problem is a multi-factor problem, spot diameter coating composition scanning speed of laser power and other implications and therefore need to be considered a good match between them, to get to meet the requirements of cladding [3-4].
Cladding plays a decisive impact on other properties, so processing parameters play a crucial role on the micro-structure of cladding layer.

Introduction Clay minerals are used as sorbents in industrial applications because of their sorption properties such as: large specific surface area, chemical and mechanical stability, hydrophilic properties, high cation exchange capacity.
Montmorillonite represents a predominant component of bentonite, and significantly influences its chemical-physical and mechanical properties.
This ratio affects most of the chemical and physical bonds on the grain boundaries of the material, which significantly affects the material properties.
Other factors related to particle size, are factors that affect the aggregation of particles (i.e. ionic strength, the quantity of organic substances, concentration, pH, temperature).
Content of clay particles, grain size granulometry and colour of the sample are also important factors which can affect the measurement.

Effects of Activator on the Properties of Brick Powder Foam Concrete Xiang Liu1,a,Yuanjun LI1,b 1School of Architectural and Civil Engineering, Inner Mongolia University of Science and Technology, Baotou 014000, China aiuxiangwd@126.com,b1990liyuanjun@163.com Keywords: Brick Powder Foam Concrete;Activation;Gypsum;Lime Abstract.The main chemical composition of waste brick is silicon dioxide,by means of chemical can stimulate its activity.In this experiment, gypsum, lime sodium hydroxide as activators,through the testing and research about the properties of compressive strength, dry density, water absorption of brick powder foam concrete,analyse the influence of three activators on the properties of foam concrete.The test results show that the:Mixing about 25% lime can guarantee the dry apparent density on the basis of compressive strength increases;Mixing 20% gypsum can make the strength and dry apparent density relatively stable;The incorporation of NaOH make the foam concrete
Compressive strength with reference to GB/T 11971—1997 Test method for mechanical property of aerated concrete.
Brick powder incorporation as cementitious material, cement and brick powder ratio of 70: 30,apparent density design of 600 kg/m3,ensure that the water-cement ratio constant during the test,Adding different dosage of activator, through the single factor experiment to analyze the effects of different species, different content of activator on the properties of foam concrete,the test process can be based on the fluidity of slurry micro adjustment of the dosage of superplasticizer.
When the gypsum mixed as activator, it can be seen from Fig.2,with the increase of the dosage of gypsum,the compressive strength of foamed concrete increased first and then decreased,the dry apparent density also show basically the same trend,but later increased.When the gypsum dosage at 30%, the 28 days compressive strength and dry apparent density of brick powder foam concrete were relatively stable,this shows that the incorporation of gypsum can stimulate the activity of brick powder, improve the mechanical properties of foam concrete.
