优质石灰岩在沥青路面的应用

石灰岩能预防沥青混凝土路面的早期水损害,有效地提高路面的使用性能,延长路面的使用寿命,减少以后的维护费用.石灰岩在沥青路面的应用包括石灰岩混合料的拌合、运输、摊铺、碾压和施工缝处理等方面.对这些环节的施工技术的探讨可为石灰岩类集料在其他地区的公路建设中应用提供经验和借鉴.

Application of High-Quality Limestone in Asphalt Pavement

Limestone can prevent early water damage of asphalt concrete pavement, effectively improve the performance of pavements, prolong the service life of pavement, reduce maintenance costs in the future. Limestone is applied in asphalt roadbed including limestone mixture mixing, transportation, paving, rolling and construction joint treatment, etc. The discussion of construction technique in these links can provide experience and reference for application of limestone aggregate in highway construction of other areas.
