Ball et al explored the factors affecting multiple chip seal layer instability[2].
Fiber seal has been significantly applied in a series of projects since introduced into China in 2007[5,6] because of its superior performance in waterproof, stress absorbing and bonding properties[7].
Conclusions can be drawn from Table 7 and Fig.3: (1) Fiber content is the most important factor affecting the shear strength of fiber seal, next are asphalt content and gravel coverage, test temperature is the smallest factor
Conclusion In this paper, an orthogonal test was developed to explore the factors affecting interlayer shear strength of fiber seal, and the conclusions can be drawn as follows: (1)Visual analysis shows that the shear strength of fiber seal increases firstly, and then decreases with the increment of material content, while decreases monotonically with the increment of temperature

Besides, through the microstructure analysis and mechanical properties testing of the formed parts, effects of dies temperature on microstructures and mechanical properties of hot-stamping square-cup parts were obtained.
However, UHSS has been extensively used in the automotive field for it possessed better mechanical properties, so it is very important to research the influence of dies temperature on mechanical properties.
In Ref 3 and 4, the relationship between heat-transfer coefficient of dies and some factors were obtained, such as dies temperature, contact pressure and so on.
Besides, by the microstructure analysis and mechanical properties testing of the formed parts, the effects of dies temperature on microstructures and mechanical properties of hot-stamping square-cup parts were analyzed.
The relationship between the dies temperature and the mechanical properties was shown in Fig.6.
