摘要
介绍了道路沥青新技术标准建议的核心指标——沥青的感温性，从众多的指标中选择了针入度指数，由三个以上温度的针入度计算求得，能较好地反映沥青的使用性能，可供修订沥青标准作为依据。
The nucleus quota-asphalt temperature susceptibility syggested by the new technology standard for paving asphalt was introduced Penetration index was chosen from many quotas,which abtained by calculating penetrations above three temperatures,the properties of asphalt usage was reflected well,and it was one base for asphalt standard revised
