郎川公路SBR改性沥青混凝土施工

由于交通量大、重载车辆多、部分地区气候恶劣,目前我国已通车的高等公路沥青路面出现了较多的早期病害,为了抵抗高温稳定性和低温冰冻的损坏,路面上面层结合料大多采用了高温性能和低温性能均很好的SBR改性沥青。该文主要介绍SBR改性沥青上面层的配合比设计和施工及其存在的技术问题。

Langchuan Highway SBR Modified Asphalt Concrete Construction

There are more early faults appearing in the asphalt pavements of the high-class highways having been open for traffic because of large traffic volume,more heavy-load vehicles and adverse weather in some regions.In order to resist the damage of high-temperature stability and low-temperature freezing,the surface binder on the pavement is mostly SBR modified asphalt with the best high-temperature and low-temperature performances.The article mainly introduces the design and construction of the mixture ratio of...
