沥青混合料的压实质量是影响沥青路面使用性能及使用寿命的重要因素,本文通过分析认为:现有规范中提供的沥青混合料压实成型工艺不能适用于所有类型的沥青混合料,在实际中应该针对不同压实机械压实机理和各种沥青混合料特点进行适当调整;在压实阶段,应主要围绕调整压实机械压实参数、优化压实机械组合并控制压实温度等3个方面提高压实质量;虽然存在一些问题,但无核密度仪、红外热成像和GPS定位技术等具有快速、无损特点的监测方法应该进一步推广应用。
The compaction quality of asphalt mixture is an important factor affecting the service performance and service life of asphalt pavement. According to the analysis of this paper, the asphalt mixture compaction process provided in the existing specifications can not be applied to all types of asphalt mixture. In practice Should be based on different compaction mechanical compaction mechanism and the characteristics of a variety of asphalt mixture appropriate adjustments; in the compaction phase, should be mainly focused on adjusting compaction compaction parameters, optimizing compaction machinery and control compaction temperature 3 Improve compaction quality; although there are some problems, but non-nuclear density meter, infrared thermography and GPS positioning technology with fast, non-destructive monitoring methods should be further promoted.
