Based on understanding of many practices of asphalt overlay on old cement concrete pavement in our country and rehabilitation of boai road in zhongshan city, this paper analyzes and studies the rehabilitation technology of old cement concrete pavement systematically, includes : ( 1 ) the assessment for structure characteristic of old cement concrete pavement a correct assessment for pavement distress and structure characteristic of old cement concrete pavement before overlay is the stick point of preventing reflection cracking and guarantee the success of rehabilitation, which requires understanding how the structure characteristic of old pavement effects the stress and reflection cracking of the asphalt overlay
本文在調查了解國內許多舊路改造實踐工程的前提下，基於中山市博愛一路的改造實踐，對舊水泥混凝土路面瀝青罩面改造進行了系統的分析研究。主要的研究內容包括： （ 1 ）原有路面結構性能的評估在瀝青混凝土加鋪罩面之前對舊水泥混凝土路面的損壞情況和結構狀況進行正確的評價是解決反射裂縫和保證加罩成功至關重要的一環，其前提就是要了解舊水泥混凝土路面的結構特性對瀝青罩面層中的應力和反射裂縫的影響。 -
This paper analyzes how structure characteristic of old concrete pavement affects the load stress of asphalt overlay by the three dimensions finite element analysis program - adina. ( 2 ) the asphalt overlay design in rehabilitation of old cement concrete pavement asphalt overlay design not only relates the distress, structure characteristic, traffic and environment of the old pavement, but also requires reasonable mechanics model, correct material parameter, effective measure of preventing reflection cracking, and so on
（ 2 ）舊水泥混凝土路面瀝青罩面改造中瀝青罩面層的設計舊路改造的罩面設計方法不僅涉及舊路面的損壞、結構狀況、交通狀況、環境因素，而且還需要合適的力學分析模型、正確的材料參數、有效的防反射裂縫措施等，內容廣泛、復雜多變，至今尚未有成熟的設計方法。 -
In order to model the portland cement concrete ( pcc ) pavement performance, about 200 pavement sections with typical environment and maintenance level were selected from four districts of guangdong province, and then an investigation was made on their pavement structure pattern, distress, traffic volume and wheel path lane coefficient
摘要為了建立水泥混凝土路面典型的使用性能預測模型，在廣東省確定了在環境條件、養護水平等方面均有代表性的四個地區，從中選取有代表性的200條路段，對其結構組成、路面損壞、交通軸載及其車道分佈進行詳細調查。
