【摘要】 路面质量是在保证施工质量时达到的,其中热拌沥青混合料的各阶段的温度控制在施工质量中起着关键作用。但在现行施工中对热拌沥青混合料的温度的控制的控制局限于点式温度计,对路面质量的控制很有限。国外实践表明红外热像仪应用于施工中,对道路施工质量的提高起着很好的作用。本文以大量试验和检测数据为基础,首先通过对比沥青混合料传统温度检测方法和红外热像仪的温度检测方法,分析并利用红外热像仪进行温度检测的特点；提出了应用红外热像仪对沥青路面施工中拌合、运输、摊铺和碾压各环节中沥青混合料温度检测方法并为施工方提供解决问题的依据,同时对比现今的检测温度的方法,根据红外热像图全面而准确的数据提供,弥补如今温度检测的不足；通过动态监测各环节沥青混合料的温度,分析了温度分布纵向、横向和竖向规律；提出了在施工中摊铺后沥青混合料的表面温度散失规律；依据我国实际情况以及施工中的现场情况,分析国内外关于温度离析的判断标准的合理性,并与PQI相结合,提出了基于沥青路面成型质量的沥青混合料温度离析评价方法和评价指标,并以这个标准应用于施工中来检测其合理性。更多还原

【Abstract】 Pavement quality is reached in the construction quality assurance, in which the temperature of asphalt mixtures play a key role. But in the current on the quality of the road construction the temperature control of the asphalt mixture depends on point-thermometer, it is very limited. It shows that the infrared thermal camera used abroad in construction improves the quality of the road construction commendably in practice.On the basis of plenty of tests and test data,the author research temperature measurement used in the infrared thermal camera.Firstly, by comparing traditional temperature measurement and the infrared thermal camera temperature measurement, the author analyse the features of the infrared thermal camera temperature measurement; the paper proposes application of the infrared thermal camera on the mixing, transport, spreading and rolling of asphalt pavement, and solves problem ontemperature detection method of the mixture, while comparing the current method of testing the temperature, according comprehensive and accurate data provided by the infrared thermal camera,it makes up for deficiencies of temperature measurement; by testing various aspects of asphalt temperature in construction, the paper analyses portrait, horizontal and vertical distribution of the temperature; proposed the temperature loss rule of the surface of asphalt mixture;according to actual situation, the author analyses on the criteria of temperature segregation at home and abroad and its reasonableness,then combination with the PQI data the author advances the evaluation indicators of temperature segregation which bases on the quality of asphalt pavement mixture, and tests the reasonableness by the standard.更多还原
