| 摘 要： | 结合南方湿热地区的气候条件和对沥青混合料配合比的设计要求,对我国现行规范中沥青混合料配合比设计方法在南方湿热地区的适应性进行了分析。研究结果表明,普通沥青混合料配合比设计结果与采用旧规范设计方法的设计结果基本一致;改性沥青混合料配合比设计的最佳沥青用量则增加0.3%,其抗高温变形能力、泛油以及抗水损害能力等长期路用性能尚需结合工程实践进一步观测。

| Abstract: | According to the climate conditions in south moist heat areas of China and the specified standard of asphalt mixture design,the adaptability of asphalt mixture design method from Technical Specifications for Construction of Highway Asphalt Pavements(JTJ F40-2004) is analysed.The study shows the results of plain asphalt mixture design are mainly accordant to the design by the outdated Technical Specifications.However,the optimum asphalt consumption of modified asphalt mixture design will increase 0.3 percent.So the high temperature stability,bleeding asphalt and water stability are still observed further based on the practical projects. |
