摘要
针对旧水泥混凝土路面加铺层结构的特点,通过理论分析和试验研究,提出了以控制弯沉差和补强层疲劳断裂为基本方法,并以公路沥青路面设计规范为验算方法来确定旧水泥混凝土路面补强层厚度的多指标设计方法。实际应用表明,该设计方法具有较好的实用效果。
Based on the theory and test anglysis, a multiply index strengthening design method of existing cement concrete pavement is proposed. The thickness of strengthing course is determined by controlling the deflection difference and the fatigue damage of the strengthening course, and by using the specifications for design of highway asphalt pavement. Some testing pavements are constructed in Zhoukou, the practical effect is satisfacted.
