Abstract:	隨著經濟發展，台灣的路網系統逐漸發展健全，政府近年來將提升路面品質作為施政重點，陸續推動各項路平專案或相關計畫，主要用意為避免路面損壞而造成民眾行車安全並提升人民對行車滿意度，道路養護巡查與維護漸漸受到重視，因此，修補材料品質之良窳亦是影響路面品質之重要因素；而現在台灣並沒有相關的修補材料試驗方法與驗收規範。本研究收集現行裂縫修補材料與坑洞修補材料，針對修補材料修補於模擬破壞試體上，進行實驗室成效試驗，期望能針對道路修補後成效特性與耐久性做進一步了解。裂縫模擬破壞修補部分，本研究將針對不同浸泡於60℃水中天數進行成效探討，成效試驗項目包括間接張力強度試驗、抗水分侵害能力試驗、回彈模數試驗與靜態潛變模數試驗，以了解有無修補的成效差別，成效試驗結果顯示，裂縫修補後有助於減緩水侵害的速度，防止水份滲入鋪面結構中進而造成告更嚴重的破壞。坑洞模擬破壞修補部分，本研究使用常溫瀝青混凝土進行修補，將對於修補後之車轍試體，進行車轍輪跡成效試驗，以滾壓次數與車轍深度為交通量推算依據，並對於修補後之使用壽命進行推算模擬，使用壽命推算結果顯示，坑洞修補以後均有2年以上之使用壽命。;Due to the economic growth in recent years, the road network system has becoming more developed. Taiwan government put the enhancement of road quality as their main policy and pushed several road grading projects or related projects. The main purpose is to avoid damage caused by road traffic and enhance driving satisfaction, which makes pavement maintenance and inspection more and more important. Therefore, the quality of repair materials is also an important factor in the quality of the road surface; Currently Taiwan doesn’t have testing method and specification for patching materials. This research collected Taiwan existing crack repair materials and pothole patching materials. By applying patching materials on damaged specimens and perform laboratory experiments to understand the performance and durability of repaired pavement. Damage to asphalt concrete pavement caused by moisture is considered to be a serious problem in Taiwan. This research evaluate the performance of cracks repair by putting specimens into 60℃ water with different days. The performance tests includes Indirect Tensile Strength Test, TSR Test, Resilience Modulus Test and Creep Modulus Test. The test results shows that repair cracks can slow down the speed of water invasion and prevent water cause more damage to pavement structure. In order to simulate pothole repair, this research use room temperature asphalt concrete to repair damaged specimens and perform Wheel track rutting test results. Using rolling times and rutting depth to simulate the remaining life of repaired specimens. The results showed that each specimens have remaining life of more than 2 years after being repaired.
