Engineering properties of asphalt concrete made with recycled glass

Taiwan is an island nation with high population density: 23 million people living in a total land area of 30 000 sq. km. The island has transformed from an agricultural society to an industrial one in the past three decades. Coming with the transformation is a cumulated waste problem. Taiwan produces nearly 5 million tons of waste each year, of which 10% is of glass materials. Bureau of Highway Department funded a research program to investigate ways of recycling the glass waste. This report presents information on the program and laboratory/field test data. Materials used in the test program included 85/100 asphalt, Type II modified asphalt, and treated glass waste. Four glass contents: 0, 5, 10, and 15%, in terms of the total aggregate weight, were used in the mixture designs for casting series of 10 cm diameter by 6.35 cm disk specimens. Tests including Marshall stability value, dry/wet moisture damage, skid resistance, light reflection, water permeability, and compaction were carried out in accordance with the ASTM and AASHTO procedures. The test results reveal that glass waste is a viable material for asphalt concrete that has been widely used in pavement that offers profound engineering and economic advantages.

唐山7.8级地震短临前兆场源特征的研究

为了通过场的动态监视和源的过程追踪以实现地震预报,以唐山7.8级地震为例,研究了震前各种前兆方法观测到的短临异常的场兆和源兆的特征。通过研究得出:场兆数量多、密度小、异常台项比低,源兆数量少、密度大、异常台项比高;台点多的地下水位和流动重力较易区分场兆和源兆的差异性;源兆主要分布在一些断裂构造形成的闭锁区内,场兆主要分布在闭锁区附近一些活动断裂及交汇部位。     

Social face for innovation in strategic alliances in China: the mediating roles of resource exchange and reflexivity

This study proposes that partners who communicate mutual respect to each other develop integrative interaction that is a foundation for innovation. Structural equation analysis suggests that reflecting upon and improving interaction between supplier and customer organizations can contribute to resource exchange between partners that results in innovation in supply chain partnerships. Results also indicate that the confirmation of social face is an important antecedent to these useful integrative interaction patterns. These findings were interpreted as reaffirming the value of relationships for making partnerships effective and that the constructive application of the value of social face can promote open discussion and innovation in China.

广西台风灾害性大风的气候特征

通过对40年广西台风大风实测资料的研究,分析了台风灾害性大风的时空分布特征,探讨其成因机制,进一步分析了各种灾害强度大风和各灾害地区大风的月分布特征及台风路径的差异性。分析表明:广西台风灾害性大风的气候分布特征为东南多,西北少,是特定的台风流场结构与广西地理地形条件相互作用的结果,并与台风活动路径和中心风力有关。大中范围风灾的高峰值出现在7月,小范围风灾的高峰值出现在8月。桂西南、桂南沿海和桂中地区台风大风主要由1类路径的台风引起,桂东南和桂东地区则受1、2类路径的台风影响。40年内共有238个台风影响广西,其中148个造成大风,造成大风的台风中约10.8%造成15站以上大范围风灾。值得注意的是,造成大范围风灾的均为进入北部湾北部海面的强台风。
