In view of a suburb major trunk road pavement failure , mainly from surface depression , cracking and slipping , water destruction , design failure , this paper analyzes the cause of destruction , proposed the preventive measure , to avoid the early destruction of the pavement , thus enhancing the quality of the road surface and lengthening the service life of the road 摘要针对市城郊某主干道的路面破坏现象，主要从路面沉陷、裂缝和滑移、水破坏、设计不合理等几个方面分析沥青路面产生破坏的原因，同时对应地提出了沥青路面破坏的预防措施，以此引起广大道路设计人员与施工人员的重视，避免沥青路面的早期破坏，从而提高路面的使用质量和延长道路的使用寿命。
The thesis , relying on the expressway in liaoning province , classifies the disease of surface of the expressway asphalt concrete pavement , analyzing mainly on the design , construction , administration and material . it summarizes the cause of the disease and influence elements , and produces some effective treatments to the disease prevention . on the basis of this , the thesis summarizes evaluation means , provides appropriate countermeasure for maintenance , and also supplies scientific basis with the high maintenance quality and low maintenance costs 本文以辽宁省的高速公路为依托，对高速公路沥青路面出现的路面病害进行了归纳分类，从设计、施工、管理及材料等方面对路面病害进行了深入的分析，总结出病害产生的原因和影响因素，并提出了病害防治的有效措施，在此基础上，通过对路面使用质量的评定，提出相应的养护维修对策，为提高养护质量，降低养护成本提供了科学依据。
The achievements are as follows : 1 ) the system model based on the whole course in of erp project theory have been put forward , erp ' s project are divided into three stages in this model , evaluation is divided into four parts , and the indexes that should been evaluated at each stages and relationship among these stages has been described systematically ; 2 ) at proposed stage , according to the characteristic of erp project , feasibility analysis should been carried out from seven respects such as managing foundation technological foundation , the fund foundation , personnel foundations , basic data , understanding and demand to erp and goal of the enterprise ; 3 ) in selecting software , 18 indexes and three factors have been put forward including system quality of the software , the fact relating to the software supplier serves , and the fact relating to enterprise , then use ahp to evaluate ; 4 ) in project implementation the evalution flow model on the basis of implementing and the index system have been proposed . the index system include 14 indexes and three respects respect which are control of the goal and plan , quality of the system use , and quality of information . 5 ) performance measurement of erp project is proposed in four respects of balanced scorecard . and according to the characteristic of erp project performance , the result of measurement should been calculated with fuzzy mathematics , then a satisfaction index can be drawn 主要成果表现在： 1 )在评价erp项目评价理论基础方面提出了基于全过程erp项目的评价体系模型，在此模型中将erp项目实施分为三个阶段，评价分为四个部分，并系统论述了各个阶段应该评价的指标，以及各个阶段的相互关系； 2 )在项目可行性分析部分，根据erp项目的特点提出了从七个方面分别是：管理基础、技术基础、资金基础、人员基础、基础数据、对erp的认识与需求，和企业的目标对erp项目进行可行性分析； 3 )在软件选型部分，提出了软件系统质量因素、与软件供应商服务有关的因素、和与企业有关因素三个方面18个指标的评价体系，并用层次分析法进行评价； 4 )在项目实施阶段，提出了基于实施过程的评价流程模型，同时提出了评价指标体系从计划，目标的控制、系统使用质量、和信息质量三个方面14项指标来评价实施过程； 5 )在项目绩效评价部分，提出以平衡记分法的四个方面评价erp项目的绩效，建立了bsc - erp评价模型，并根据erp项目绩效的特点提出了用模糊数学对评价结果进行计算，得出一个满意程度指标。
