本研究係探討焊道渣作為道路基底層級配再利用之工程特性研究,從巨觀做深入研究,並進行一系列試驗得到以下結論:
第一部份作為道路基底層級配材料
1.焊道渣除扁平率偏高級配不佳外,其CBR值在98%γdmax時其CBR值為188%,在95%γdmax時其CBR值為176%,其抗磨損率為21.2%及健性為0.53%,浸水回脹值均為零,試驗結果遠超過我國公路工程道路基底層施工規範要求,為一種優至良之路基材料。
2.從SEM晶相觀察、XRD及XRF X光繞射及螢光分析化合物組成觀察,證實焊道渣由SiO2、Al2O3、CaO、Fe2O3MgO等氧化物組成。
3.以王水消化試驗分析,根據溶出結果證實焊道渣在自然環境下焊道渣應可作為工程土方及基底層材料再利用,對於土壤、地下水等自然環境應不致造成影響與污染。
第二部份作為MRC粗細骨材
1. 若以硬固時間約3~5小時考量,其抗壓強度約3~7kg/cm2,就MD-1.0~MD-1.6及MD-1.0G~MD-1.6G等8個配比而言,養治1天、3天及7天其抗壓強度皆能滿足MRC作為道路基底層抗壓強度要求。
2. 配比中添加水玻璃其早期強度較高,其中以MD-1.0G抗壓強度最大效果最顯著,但是添加量以不超膠結量的1%為宜,否則晚期抗壓強度有逐漸下趨勢。

Weld Slag has good compressive strength, quick permeability, stability of physical and chemical properties, high alternative pellets etc. It is a good construction material .It used as base layer material and Multifunction Recycling Concrete and replaced the natural grade had become essential. After a series of test, and obtained the following conclusions:
The first part used as base layer material
1.In addition to the more flat, when it is 98%γdmax,CBR value is 188%, it is 95%γdmax,CBR value is 176%, resistance to abrasion value is 21.2%, soundness is 0.53%,swelling values approach to zero, has met the requirements of the road base layer specification, its excellent to good base layer material.
2. From the SEM observation of crystalline phase, XRD and XRF analyzed compounds composition, Weld Slag confirmed to compose from the SiO2, Al2O3, CaO, Fe2O3, and MgO and other oxides.
3. According to dissolution results have confirmed, under acidic conditions, in the natural environment, weld slag should be reused as the base layer material earthwork, therefore, will not cause negative effect to the quality of earth and underground water.
The second part used as aggregate of Multifunction Recycling Concrete
1.Considered in terms of 3 to 5 hours hard time, compressive strength of about 3 ~ 7kg/cm2, from MD-1.0 to MD-1.6 and from MD-1.0G to MD-1.6G etc. 8 ratios, curing 1day, 3days and 7 days, compressive strength of multifunction recycling concrete has met the requirements of the road base layer specification.
2.Adding sodium silicate ratio has a higher early compressive strengththe MD-1.0G ratio has maximum compressive strength, the most significant effect, but does not exceed 1% of cement amount, otherwise, late compressive strength there have been gradually declining trend.
