Different gradation types may have different particle contact behaviors for asphalt mixture, so that it holds diverse pavement performances. The particle contact theory explains the particle contact behaviors law during movement. A particle contact behaviors model was established, which is easy to describe and apply on the spot. A line contact stiffness model was used to simulate particle contact behaviors for gradation types of CA0.2, CA0.4, CA0.6 and CA0.8 when particle of asphalt mixture is moving with dead weight. Their pavement performances were verified with Marshall test, wheel tracking test, gyratory compacting test and the index of potential energy test under optimum asphalt content. Test results show that their service performance is identical to simulation result of particle contact during movement with dead weight. With the help of the research, it can supply some theoretical and applicative bases for an optimum mixture gradation design and indoor gradation simulating design for asphalt mixture.

Women With Disability

The underrepresentation of women in the Paralympics movement warrants attention as the world prepares for Atlanta 1996, when Paralympics (conducted after the Summer Olympics) will attract approximately 3,500 athletes with physical disability or visual impairment from 102 countries. Barriers that confront women with disability, the Paralympic movement, and adapted physical activity as a profession and scholarly discipline that stresses advocacy and attitude theories are presented. Two theories (reasoned action and contact) that have been tested in various contexts are woven together as an approach particularly applicable to women in sport and feminists who care about equal access to opportunity for all women. Women with disability are a social minority that is both ignored and oppressed. Sport and feminist theory and action should include disability along with gender, race/ethnicity, class, and age as concerns and issues.
