摘　　要：通过路面状况、路面强度、路面行驶质量、路面抗滑性能及交通量的调查,对海南东线高速公路路面进行了客观、全面的评价,对造成其路面病害的各种原因进行分析.分析结果表明,造成旧沥青路面裂缝、车辙及水损害等病害的主要原因在于:沥青面层材料选型与其厚度不匹配,海南气候条件特殊,施工质量不良,交通重载与超载等.According to the survey including pavement condition,pavement strength,pavement riding quality,pavement skid-resistant performance and traffic volume,the pavement condition was evaluated objectively and comprehensively.Meanwhile,the various causes of pavement disease were analyzed.The analysis results show that,the main disease is caused by old asphalt pavement crack,the rutting and moisture damages were induced by the mismatch between asphalt surface material type and its thickness,the special atmosphere condition of Hainan,the poor construction quality,the traffic heavy overload and overloading,etc.
