公共建設辦理道路新闢或瀝青混凝土面層刨鋪常見有瀝青混凝土厚度未達設計值之施工情形，不足時並非必然重新加鋪，係以工程契約予以收受、減價收受、加鋪或重新刨鋪等方式處理，亦常見道路路基層較為軟弱導致路面反覆損壞情形，瀝青混凝土鋪設厚度不足及鋪面材料強度差異對於道路使用年限有何影響，本研究以最常見之疲勞裂縫及車轍變形為破壞形態，予以評估比較其使用年限、經濟性及功能效益。
本研究首先對臺中市市區道路作現況及交通量調查，了解其使用狀況外，再依據現行鋪面設計狀況，模擬完整路面、瀝青混凝土厚度不足、各層鋪面材料強度減損等狀況詳作具體作力學分析，並比較各項狀況改變對於鋪面應變變化、使用年限影響及對於何種破壞有更劇烈之影響做一分析比較，藉以了解各種變異因素對力學影響及後續可能遇見之破壞方式，並提出具體建議方案。
研究結果顯示瀝青混凝土厚度減損對於柔性路面使用年限之影響甚鉅，鋪面預期之使用年限減損百分比常高於厚度減損百分比，另針對瀝青混凝土材料彈性係數較差之鋪面對於疲勞破壞及車轍之影響大略一致、對於路基軟弱之鋪面材料，其車轍破壞影響較為劇烈，上述結果可作為相關規範訂定及對於鋪面破壞預防及評估之使用。

When there are public constructions of the pavements on new roads or the repairments of the existent roads, there are often defects due to insufficient asphalt thickness. The workarounds are often not to require the contractors to scratch off the asphalt layers and repave according to the contract but just accept with discount or have the contractor pave another layer of asphalt on it. Also, if the subgrade of the road isn’t compacted firmly enough, it will cause the road damaged repeatedly. To what extent does the insufficient asphalt thickness and the variation of the strength of the materials of the pavement influence the service life of the road? This research focuses on the estimation of the duration, the cost benefit analysis and the evaluation of the function of the pavement based on the destructive patterns of fatigue crack and rut deformation.
This research uses the municipal roads of Taichung City as the subject of study. Besides understanding the usage status of the roads, we also simulate the conditions of the undamaged roads, roads with insufficient asphalt thicknesses and roads with each layers impaired in various ways and analyze with mechanics specifically so that we can understand the influence due to each variable factors and the probable damage patterns and offer specific suggestions according to the results of the experiments.
