| 摘 要： | 采用落锤式弯沉仪(FWD)对上海地区路面结构进行评价,发现沥青层反算模量与沥青层温度间存在较好的指数关系,建立了上海地区道路结构的沥青层反算模量与沥青层温度回归模型,推荐了沥青层反算模量温度修正系数值.将沥青层反算模量温度修正结果与室内外模量测试结果进行对比,结果表明所推荐的温度修正系数具有较高的可靠性. |

| Abstract: | Falling weight deflectometer(FWD) tests were conducted at the pavements in Shanghai.The collected data were used to back-calculate the modulus of asphalt pavement layer.There was a good exponential relationship between the pavement layer modulus and the asphalt layer temperature.The equation of temperature and modulus was developed for the pavements in Shanghai.The temperature adjustment factors were proposed to correct the back-calculated modulus at any temperature to reference temperature modulus.Comparis... |
