概述了近年来我国公路建设所取得的成绩 ,重点介绍了对道路沥青在数量和质量上的需求情况。 1999年我国道路沥青产量为 2 80 0kt/a ,其中高等级道路沥青占 5 4.6 %。预计今后几年道路沥青的需求量约为 40 0 0kt/a 。
The domestic highway constructions in recent years are reviewed. The quantity and quality of road asphalt demands are highlighted. The total road asphalt production in China was 2 800 kt/a in 1999, in which the high grade road asphalt accounted for 54.6%. It is estimated that the demand of road asphalt will reach 4 000 kt/a in the forthcoming years and the growth rate of high grade road asphalt will be enhanced.
