本研究嘗試以發泡劑及EPS作為輕質材料，研發重量輕、早期強度佳、透水性高的輕質透水CLSM，作為重建山區道路坍滑路基的輕質回填料。本研究試驗分兩階段進行:第一階段先以發泡劑作為輕質材料，第二階段則以EPS作為輕質材料。經由試驗結果顯示，若採用發泡劑，則CLSM之早期(24小時)抗壓強度過低，無法滿足強度要求(7 kg/cm2)；需另添加早強劑將早期強度提升至目標值，但早強劑會使得單位重上升，滲透係數也降至趨近於零。另一方面，因發泡劑價格高，導致CLSM成本高於一般市售價格。當採用EPS作為輕質材料時，可以調配出量輕、早期強度佳、透水性高的輕質透水CLSM，其試驗數據皆可符合試驗目標，可作為重建山區道路坍滑路基之輕質透水CLSM。而且若能採用現地之坍方土石作為粗骨材，則其價格可低於一般市售CLSM，可兼具實用性和市場競爭性。

This research is aimed to develop a light weight porous CLSM with high early (1-day) strength by using foam agent and Expandable Polystyrene (EPS) nuggets as the lightweight in-fill materials. The experiment works are carried out in two groups: one uses the foam agent to reduce the weight of CLSM; the other uses EPS nuggets. The results of using foam agent showed that the 1-day strength of the material was too low (< 7 kg/cm2). To increase the early strength, accelerator was added to speed up the hydration process of cement. Although the early strength was increased to be larger than 7 kg/cm2, the unit weight was increased too and the coefficient of permeability dropped to nearly zero. Finally, the cost of CLSM prepared with foam agent is much higher than the ordinary CLSM. It makes the CLSM prepared from the foam agent not competitive in the market. In comparison, the CLSM which used EPS nuggets to replace part of the coarse aggregates was able to meet the requirements of light weight, good early strength, and high permeability set in this research. It is a very good material to rebuild the lost road base for the mountain road. If the coarse aggregates can be further replaced by the debris from the landslide site, this CLSM can be a cost competitive back fill material in the market
