一种适用于隧道用阻燃SBS沥青复合式路面结构
摘要：
本实用新型公开了一种适用于隧道用阻燃SBS沥青复合式路面结构，包括在路基上方沿着靠近路基方向依次铺设的上面层、中面层、下面层、半刚性基层、碎石基层，其中：所述的上面层是厚度为5～8cm的温拌阻燃SBS沥青，中面层的厚度为8～10cm，下面层的厚度为8～12cm，半刚性基层厚度为35～40cm，底基层采用15～20cm级配碎石或者未筛分碎石与水泥组成。本实用新型针对于高速公路隧道沥青路面的施工条件和环境，采用半刚性基层良好的抗变形能力和抗剪切能力减少SBS沥青路面的车辙量，使用的温拌阻燃SBS沥青可以在隧道内发生火灾事故时最大程度的减少对人的伤害，采用连续级配混凝土基层提升路面结构的稳定性和承载能力，从而更加有效的提高隧道路面的寿命和使用性能。
摘要（英）：

The utility model discloses a be applicable to tunnel with fire -retardant SBS pitch combined type road surface structure, include in road bed top along being close to the last surface course that the road bed orientation laid in proper order, well surface course under, surface course, semi rigid base course, macadam base, wherein: last surface course be that fire -retardant SBS pitch is mixed to the thickness temperature that is 5~8cm, the thickness of well surface course is 8~10cm, the thickness of lower surface course is 8~12cm, semi rigid base course thickness is 35~40cm, the underlayment adopts 15~20cm graded broken stone or is unscreened the branch rubble and forms with cement. The utility model discloses to execution conditions in highway tunnel bituminous paving and environment, adopt good anti deformability of semi rigid base course and anti -shear performance to reduce SBS bituminous paving's rut volume, maximum reduction was to people's injury, the stability and the bearing capacity of adoption continuous grading concrete -based layer promotion road surface structure when the temperature of use was mixed fire -retardant SBS pitch and can be taken place the fire incident in the tunnel to more effectual improvement tunnel road surface's life -span and performance.
