寒冷地区公路沥青路面厚度计算方法及算例

Thickness Calculation Method of Highway Asphalt Pavement in Cold Area and Calculation Example

针对寒冷地区公路沥青路面设计中应重点考虑的问题，以我国《公路沥青路面设计规范》（JTG D50—2006）和弹性多层体系理论为基础，建立了系统、简便的寒冷地区公路沥青路面厚度计算方法．实际算例表明，应用该方法能够准确地进行寒冷地区公路沥青路面的厚度计算．

According to key problems of highway asphalt pavement design in cold area, a systemic and simple thickness calculation method of highway asphalt pavement in cold area was established based on Highway Asphalt Pavement Design Rules （JTG D50-2006） and elastic multi-layer system theory. An example result shows that this method can be applied to calculate accurately the thickness of highway asphalt pavement in cold area.
