The Green’s-function and the force- and energy-balance equations for steady states have been used to study the electron transport and its pressure effect with the influence of impurities and acoustic-phonons in Au1-xTixO3 octahedral crystal potential. The results show that there is a minimum temperature range of electrons as the center-of-mass velocity of electrons increasing, and external pressure effect plays an important role in the contributions of impurities and phonons.

An unanticipated sideeffect of China’s developing economy was the increase in heavy road trafficvehicles utilizing high pressure tires on both new and old infrastructure.Today the extent of rutting has become one of the main forms of asphalt road surfacebreakage. To improve the robustness and high temperature properties of roadsurfacing asphalt, a new high-modulus material has been developed and used tomodify normal road petroleum asphalt. The results from laboratory experimentsconducted at the Jiangsu Baoli Asphalt Co., LTD and real road trials inPeople's Democratic Republic of Algeria, Shanghai, Shanxi and Jiangsu provincein China, indicate that the high-modulus asphalt performed significantly betterat higher-temperatures when compared to samples of more commonly used asphaltmixtures. The high-modulus additive (No. ZQ-1) was prepared in Jiangsu BaoliAsphalt Co. LTD, and the basic production process, the basic properties as wellas the effection to base bitumen was analysed in the paper. And the DynamicStability was evaluated using an automated rut-depth measuring system. Thewater stability and low temperature properties were also discussed. Themodified asphalt material has comparable storage and usage costs to existingutilized asphalts though with enhanced high-temperature properties.
