In recent years, China's highway construction as the center (by the end of 2003 the national highway mileage will reach 30 thousand km), to obtain the rapid development of highway construction, highway asphalt demand is increasing year by year, the 2002 national road asphalt dosage is 8 million 200 thousand T, the domestic heavy traffic asphalt asphalt 4 million 600 thousand T, 1 million 400 thousand T, imported asphalt content 2 million 200 thousand T, the 2003 national road asphalt amount
will be more than 9 million T. Road asphalt technical requirements of the Ministry munications the promulgation and implementation of the "" (hereinafter referred to as the "new standard") is to improve the asphalt quality standards for the correct understanding of the "new standard" of asphalt technical indicators, analysis research is necessary.
1 determine the asphalt road technical indicators of factor road quality factors 1. load factors
With the increase of the traffic volume and the increase of axle load, to reduce the fatigue damage of pavement load, the pavement needs better asphalt material with reasonable consistency, cohesive force and viscoelasticity. In traditional asphalt technical indexes, ration, temperature, ductility and wax content reflect the adaptability of asphalt to loading factors. 1., temperature factors, asphalt pavement under design load, in the high temperature does not produce plastic fl
