SMA沥青混合料应用中存在问题的改进措施

Improvement Measures of Problems Existing in Application of SMA Asphalt Mixture

沥青路面早期损坏,与沥青混合料配合比设计不当、对主要技术指标控制不严和混合料质量有着直接的关系。通过原材料试验进行SMA沥青混合料配合比设计并对其路用性能进行检测,各项指标满足规范要求,并根据多年对施工和检测工作的实践,通过分析SMA沥青混合料在应用中存在的问题,提出改进措施,以便对配合比设计和对施工、生产中的每一环节严格把关,达到施工过程中进行质量控制的目的。

The early damage of asphalt pavement has the direct relations of unsuitable mix proportion design of asphalt mixture, non-strict control of main technical indexes, and the mixture quality. The mix proportion of SMA asphalt mixture is designed through the raw material test, and its pavement performance is detected. Various indexes satisfy the standard requirements. Based on the construction and detection practices for many years, the article analyzes the problems existing in the application of SMA asphalt mixture, puts forward the improvement measures so as to strictly check on the design of mix proportion, and every link of construction and production in order to reach the objective of quality control in the construction process.
