阻燃型隧道沥青混凝土路面专用养护剂的性能评价

Performances Evaluation of Flame-Retardant Special Maintenance Agent for Tunnel Asphalt Concrete Pavement

对一种新开发的阻燃型隧道沥青混凝土路面专用养护剂进行研究,首先对该养护材料的阻燃性能和在防止或减缓沥青老化方面的功能进行评价,然后着重考察其对隧道沥青混凝土路面结构透水性和抗滑性的影响。结果表明:该阻燃型养护剂能有效改善老化后的基质沥青和阻燃改性沥青的三大指标,提高隧道沥青混凝土路面的不透水性,且几乎不降低抗滑性。

A new flame-retardant special maintenance agent for tunnel asphalt concrete pavement is studied. Firstly, the function of the maintenance agent on anti-ageing property of asphalt and flame-retardant property is evaluated, and then the permeability and anti-slip performence of tunnel asphalt concrete pave-ment with the maintenance agent are focused on. The result shows that the flame-retardant agent can effectively improve the anti-ageing property of asphalt and improve the impermeability of tunnel asphalt concrete pavement almost without reducing the sliding resistance.
