Cruising in the Orange Jeep through the North Fork of Coal Wash brought back memories of my first visit to the San Rafael Swell 30 years ago. I cranked the wheels sideways, floating them through the deep sand.
The abundance of granular waste materials coupled with their successful reuse in construction fills has provided sustainable alternatives to a rather expensive quarried natural rock aggregate. This study focuses on the application of coal wash (CW) as an admixture to mitigate the undesirable shrink and swell characteristics of expansive black soils under unconfined compression loading. CW is a by-product of the coal industry that requires an enormous area of landfill for storage. These landfills pose a serious environmental problem because coal is still being produced in many parts of the world. A series of unconfined compression tests were conducted on CW-soil mixtures with and without wet and dry cycles; these wet and dry cycles mimic the shrink and swell characteristics of expansive soil observed in the field. Our findings show that cracking and shrinking impact the fabric of CW-soil over time, which reduces their shear strength. The incorporation of CW into black soil reduces its s
