COMPOSITION FOR PAVING SOIL AND METHOD FOR PAVING SOIL ROAD BY USING THE SAME
The present invention relates to a composition for paving soil and a method for paving a soil road by using the same and, more particularly to a composition for paving soil, which stabilizes soil by activating latent hydraulic property of slag fine powder, and reducing water content in the soil by using a volume expansion effect and an exothermic reaction of calcium oxide (CaO) contained in incineration residuals, and to a method for paving a soil road by using the same. The composition for paving soil may include, with respect to 100 parts by weight of natural sediment: 5-20 parts by weight of blast furnace slag; 3-10 parts by weight of high calcium-incineration residuals containing at least 15% of CaO and at least 5% of ferric oxide (Fe2O3); and 3-10 parts by weight of desulfurization dust containing at least 5% of Fe2O3.
본 발명은 황토 포장 조성물 및 이를 이용한 황토길 포장공법에 관한 것으로서, 보다 상세하게는 슬래그미분말의 잠재수경성을 활성화 시키고 소각잔재에 다량 함유된 CaO의 발열반응과 체적팽창작용을 이용하여 토양의 간극수를 제거하고 함수율을 저감하여 토양을 조속히 안정시키는 황토 포장 조성물 및 이를 이용한 황토길 포장공법에 관한 것이다. 본 발명에 의한 속경형 황토 포장조성물은 천연토사 100중량부에 대하여 고로슬래그 미분말 5~20중량부와, 산화칼슘(CaO)함량이 15% 이상이며 산화제이철(Fe2O3) 함량이 5% 이상인 고칼슘 소각잔재 3~10중량부, 산화제이철(Fe2O3) 함량이 5% 이상인 탈황분진 3~10 중량부를 포함한다.
