随着国民经济的快速发展,交通流量载荷的强度愈来愈大,路面养护维修的工作量及所消耗的资金日益增加。有系统地实行预防性养护工作是延长道使用路寿命、减少寿命周期费用行之有效的方法。2002至2003年度,宁沪高速公路镇江管理处采用沥青再生剂对宁沪高速公路镇江管理段进行了预防性维护,在提高养护水平、保证路面完好率和降低养护成本方面取得到了令人满意的效果。
With the rapid development of the national economy, the intensity of traffic flow load has been increasing. The workload of maintenance and repair of pavements and the funds consumed by them have been increasing. The systematic implementation of preventive conservation work is an effective way to extend the life of roads and reduce the cost of life cycles. From 2002 to 2003, the Zhenjiang Management Office of Ninghu Expressway adopted asphalt regenerant to preventative maintenance of Zhenjiang management section of Ninghu Expressway, and achieved satisfactory results in improving the maintenance level, ensuring the road intact rate and reducing the maintenance cost effect.
