To research the grading applicability of Lucobit modifier and make it adapt to China's basic national conditions very well, the gradations of SUP-20 was selected to research mix design and pavement performance in the text. First, the mix design of SUP-20 without Lucobit is researched. Then the performance of SUP-20 is verified including the high temperature, low temperature and water stability performance of common asphalt mixture. At last the performance comparison between SUP-20 asphalt mixture with 7% Lucobit and without is carried out. Results show that the performance of SUP-20 asphalt mixture with 7% Lucobit and without can all meet the requirement. Compared with the performance of SUP-20 asphalt mixture without Lucobit, the low temperature and water stability performance with Lucobit have a little improvement and the high temperature performance improves a lot. So Lucobit modifier can greatly improve the high temperature performance of SUP-20 asphalt mixture.

Information hiding in a resources section’s redundancies has large amount of watermark embedding, and the software watermarking based on PE file resources section format has high concealment. This paper combined this two algorithms’ advantages, and embedded the watermark information in these two ways. It also introduced the information hiding technology based on ICON file and binder technology to realize the tamper-proof function of the watermark. Experiments shows that this scheme not only improves the embedded information capacity, but also overcomes the problem that the embedded watermark are susceptible to tamper-proof attack. So the new scheme improves the watermark’s comprehensive performance, and create a more secure and robust software watermark.

Warm Mix Asphalt (WMA) technology has become increasingly popular in pavement construction because of its environmental benefits and its fine engineering properties. In order to optimize mixing performance of WMA, four kinds of warm mix additives used in China were evulated by viscosity testing. Thus, this paper is mainly to reduce bitumen viscosity, which in turn improves mix workability, produces fewer emissions, and generally creates better working conditions. Results identified that the Sasobit additive has a large viscosity reduction and has a fine workability, and is appropriate for pavement construction.
