In order to adapt the maintenance activities well, this paper makes some ameliorations, as follows : ( 1 ) it is considered not so pertinent in this paper to take road user cost into account of total cost, and an advice of using pavement serviceability performance for benefit is given. ( 2 ) when evaluating the average of the road network serviceability, this paper put forward to using weighed geometric mean to calculate pqi. ( 3 ) bringing in a new idea of checking the reasonability of classifying pavement state and typical measure by transfer probability
為盡可能使其反映實際的養護規律，本文在前人研究的基礎上，提出以下改進： （ 1 ）在建立費用模型時，認為在我國現階段，考慮用戶費用有不妥之處，提出以路面使用性能作為用戶費用的映象，以路面使用性能作為效益的評價指標； （ 2 ）在評價路網平均服務水平時，提出用加權幾何平均值來計算路面使用性能綜合評價指標pqi ； （ 3 ）提出了利用轉移概率檢查狀態的劃分和典型措施的合理性的新思想； （ 4 ）在求解markov決策模型時，通常使用的方法是線性規劃法，本文闡述了另外兩種求解的方法：策略迭代法和整數規劃法。 -
It is stipulated in the current " rule & regulations on maintenance technology of asphalt roads " that, pqi are adopted as the evaluation indexes in the road comprehensive evaluation, which is the weighted average of the road functions ( including pci, rqi, ssi, and sfc ). the roads " whole situation is reflected in the using and maintaining process
現行的《公路瀝青路面養護技術規范》規定：路面綜合評價採用pqi作為評價指標，是對路面使用性能（包括pci 、 rqi 、 ssi 、 sfc在內）加權平均后的綜合評價，反應了路面在使用和養護過程中的總體情況。 -
( 5 ) from the point of the pavement function request and the whole evaluation system, define the pavement quality index ( pqi ) which represents the holistic pavement structure performance, establish the evaluation model and rating standard, apply the fuzzy theory, the theory of set pair analysis and the gray system theory in the evaluation of pavement performance, and create some appraisal models
（ 5 ）從路面的功能需求和評價系統的整體出發，對路面結構綜合使用性能指數pqi進行了定義，並建立了相應的評價計算體系和分級標準，探討了模糊數學理論、集對論和灰色系統理論等在路面結構使用性能評價中的應用，建立了多個評價分析模型。 -
Finally, previous model is related to expert ’ s mark and maintenance cost, by summarizing and analyzing much survey data, according to condition data and corresponding maintenance countermeasure, pqi and corresponding maintenance cost is counted, model between pqi and maintenance cost is established, which has objectivity and provides a compact reference method for expressway supervisor and maintenance countermeasure priority
最後，針對已往建立的基於養護費用與專家打分費用模型，通過對大量的實際調研數據總結分析，依據測定的路況數據及相應選定的養護對策，計算路段的pqi值及相應的養護費用，建立以實測數據為基礎的路面綜合評價指標與養護費用的關系模型，使其更具有客觀性。 -
Firstly, the paper researches on the assessment of the expressway asphalt pavement performance, practice measure data of ten typical sections are selected from survey expressway, establishes weighed geometric mean to calculate pqi, which includes sri parameter that could enhance model precision
首先，對高速公路瀝青路面使用性能進行評價，從課題所調研的高速公路中，選取10個典型斷面的實測數據，建立基於加權幾何平均值的瀝青路面綜合評價模型pqi ，並在模型參數中增加抗滑性能指標sri ，提高評價模型精度。
