  • 在日漸匱乏的粒料資源中,再生瀝青混凝土將成為未來鋪面工程發展的主流。行政院公共工程委員會規定瀝青混凝土挖(刨)除料不得超過40%。然實際上瀝青混凝土挖(刨)除料用量檢測不易,造成材料品質變異性極大,對鋪面的績效更是不易控制。因此本研究內容藉由實驗室物性試驗及量測現地路面狀況指標,以探討再生瀝青混凝土鋪面基本性質與路面績效之關係。
    由試驗結果得知在含油量試驗,於鋪面破壞比較時,可將含油量之影響視為等量齊觀。黏滯度試驗則試驗值較設計值來的高。篩分析試驗在再生料洗油後之篩分析皆符合規範之規定,但須注意黑石頭效應,避免級配有偏細之現象。最大理論密度試驗鋪築後孔隙率將隨著使用年限增加而降低,最終趨於緩和。穩定値與流度值試驗當疲勞破壞時,將使得穩定值下降、流度值上升,表示其抗疲勞能力較新鮮料來的差。PCI值分析中,並無顯著差異性,可取平均值加以分析。再者從PCI值與RAC關係來看含油量過高將影響整體之路面性質,導致其餘破壞的產生,降低了PCI值。黏度值越高則PCI值隨之將低,顯示老化後之瀝青混凝土較無抵抗破壞之能力。流度值越小,PCI值自然提高。再生比例的增加,穩定值上升而流度值下降,黏滯度隨再生比例之下降而減少,含油量大小並不隨RAC再生比例而有所變化。

    In day by day deficient a grain of material resource, the recycled asphalt concrete will become the mainstream of pavement development of shop front in the future. The public construction commission can't exceed 40% to get rid of the material to dig ( planes ) stipulating the asphalt concrete . It is difficult for the asphalt concrete but in fact to dig ( planes ) and get rid of material consumption and measure, cause the qualitative change opposite sex of the material product to be great, more wayward to paving performance. So a research contents examine the state index of shop front now with the thing test and quantity of the laboratory , in order to probe into the relation of the recycled fundamental property of shop front of asphalt concrete and road surface performance.
    Learnt by the result of the test and tested in oil content, when the shop front is destroyed and compared, can regard the influence of oil content as regarding as equal . Viscosity was tested the testing value relatively the designing value came high. Sieve analyse and test the sieve after the recycled material has the oil and analyse that all accords with the normal regulation, but must pay attention to the black rock effect , prevent grade from being furnished with leaning towards the fine phenomenon. The hole rate will be reduced as service life increases after the standard method of test for max specific gravity is paved and built, tend towards the relaxation finally. Stability and flow Is it when destroy with fluidity value tiredly , make stability value drop , flow value rise to test, express the difference that fresher material comes that it resists tired ability . In PCI value was analysed, has not been showing the difference , the desirable average is analysed . Moreover it will influence the road surface nature of the whole that oil content is too high according to PCI value and RAC relation, the production causing the others to destroy, has reduced PCI value. The higher viscosity value is PCI value will be low thereupon , will show that the asphalt concrete after wearing out has not relatively resisted the ability to destroy. The smaller flow value is, PCI value improves naturally . The increase of the recycled proportion, stability value rises but fluidity value drops, viscid degree reduces with decline of the recycled proportion, the size of oil content does not change with RAC recycled proportion .
