摘要:
由于沥青混合料为多相体,其热物理特性参数的测试较为困难.随着对抗车辙等沥青混合料高温特性研究的深入,发现针对沥青混合料导热系数等热物理参数测试方法相关研究很少.基于瞬态热线法,采用TC3000导热系数仪,针对四种典型沥青混合料进行导热系数测试.试验结果分析发现就内部组成因素而言,沥青混合料导热系数随着空隙率增大而减小,随4.75 mm以下细集料通过率增大而减小,随沥青用量增大而减小,但其减小不显著.另一方面,在外部环境变化时,混合料导热系数随温度增加有先减小后增大的趋势,浸水时较干燥时导热系数也提高,压力水平变化对导热系数测试结果影响不大.
Abstract:
It’s difficult to test the asphalt thermal physical parameters because asphalt mixture is a heterogeneous material. Little research work has been done in this area. With the development in asphalt mixture anti-rutting property study, it’s necessary to look for a proper asphalt mixture thermal conductivity coefficient testing method. In this paper, thermal conductivity coefficients of four typical asphalt mixtures are obtained using transient hot line thermal conductivity coefficient testing system, TC3000. These four mixtures have different grade, different asphalt content and different air void ratio. Result analysis shows that thermal conductivity coefficient drops as void ratio increases and thermal conductivity coefficient decreases as fine aggregate passing ratio increases. Thermal conductivity coefficient decreases slightly with increase of asphalt content and it first reduces and then increases when the temperature increases. The coefficient enhances when the mixture is treated with water. Pressure level doesn’t influence the coefficient apparently. Research results can be helpful in the study on pavement temperature field calculation and control. Key word:road engineering; asphalt mixture; thermal conductivity; transient hot-wire method (本文编辑 桂智刚) (上接第198页) The elastic lateral stiffness of single sway rod eccentrically braced steel frame SU Mingzhou, LI Shen, FAN Ruichang, ZHANG Qian (Key Laboratory of Structural Engineering and Earthquake Resistance of the Ministry of Education, Xi’an Univ. of arch.&Tech., Xi’an 710055, China) Abstract: In order to identify loading path and internal force distribution of single sway rod eccentrically braced steel frames(‘SSR-EBF’ in brief)andcompute story driftsand link rotationsconveniently, the formulas of elastic axial forces of brace and shear force of link subjected to lateral loads have been proposed based on the fundamental assumption of structural mechanics, and then the elastic lateral stiffness formula of SSR-EBF is put forward on the basis of the small deformation assumption and Hooke’s law. The analysis results of 30 examples indicate that, the error of elastic lateral stiffness formula is approximate 10%, and the accuracy of formulas of internal force is sufficiently. The simplified design method of brace rod is suggested
