[Abstract]:At present, the pavement performance test is mainly manual inspection regularly and limitations more, and only when the pavement surface can be detected, it is difficult to discover the internal damage of pavement. It belongs to the detection results of pavement damage, rather than the possible damage prediction, preventive maintenance measures therefore formulated on the basis of the road is only a kind of routine maintenance of disease, is not the true sense of the preventive maintenance. So we need the development of on-line detection of structural response and state using sensor and damage identification technology, and state recognition of pavement performance and potential damage to real time. This paper puts forward the concept of asphalt pavement health monitoring and evaluation system for pavement design, construction, provide the performance information and scientific decision-making on the basis of test and maintenance decision. The main contents are as follows: Based on the asphalt The pavement damage types and causes, the failure mode control of asphalt pavement research, two typical control of semi-rigid asphalt pavement damage model: cracking and permanent deformation. The cracking damage, fatigue failure modes of the main control for semi rigid base crack, fatigue cracking of asphalt layer; permanent deformation control the failure mode is the main deformation of asphalt layer. Based on relevant research at home and abroad, put forward asphalt pavement health testing evaluation system, evaluation of the current asphalt pavement prediction model research and selection of health. When can identify the semi-rigid surface bottom layer tensile stress (strain), monitoring of asphalt surface the rutting compressive stress by vertical layers to identify. Put forward pavement health monitoring method based on the time domain, the time domain road pavement damage superposition analysis ideas and methods. In the southern Jiangxi area temperature field data measured on the highway, the temperature effect on the asphalt pavement and sunny, cloudy, the pavement temperature field distribution of rainfall and other weather patterns; analysis of the plain area, the temperature field of three kinds of terrain in Hilly and mountainous areas of the distribution and the temperature effect on the embankment. Road cutting and other local terrain conditions, the statistics of the asphalt pavement internal temperature and temperature gradient distribution was established. According to the experimental results of three kinds of terrain conditions of temperature prediction model and temperature adjustment coefficient. The dynamic modulus of asphalt mixture material design is the most crucial parameters system of mechanics empirical method. Study on dynamic law the modulus of the influence on the temperature and frequency are SMA-13, AC-20, ATB-25 asphalt mixture dynamic modulus master curve of dynamic modulus prediction model. With the help of Witczak, based on When the temperature field of pavement pavement test, each layer of mixture dynamic modulus of temperature correction, and the dynamic characteristics of the measured temperature field under the asphalt layer modulus distribution were analyzed. On the basis of field mechanical response results, established the analysis model of Asphalt Pavement Based on dynamic modulus was analyzed. The influence of pavement mechanical uniaxial load and multi axial loads, effects of load, speed, temperature and surface roughness influence on the response of the pavement, and carry on the research of load frequency on different vehicle speed and depth of pavement. According to temperature measurement, based on the dynamic modulus of asphalt mixture with temperature variation, analysis of mechanical response positive and negative temperature of pavement, the mechanical response on temperature distribution, mechanical response of asphalt pavement on pavement mechanical response to extreme temperatures and different weather conditions. Based on response surface method, Study on the relationship between temperature and mechanical response of pavement layer, layer temperature sensitivity to were analyzed. Then build the pavement mechanical interaction of temperature - load speed response prediction model. And the real-time temperature of asphalt pavement condition was predicted. The analysis of the existing issues of maintenance decision, is proposed asphalt pavement maintenance decision method based on health monitoring.
