Characterization of Compost Amended Soils
Pavement cracking is a major problem in areas having expansive clays. There are a number of treatment methods to prevent and reduce the extent of cracking on the roadways, and compost treatment is one of the ways to prevent cracking in soils due to fibrous and hydrophilic nature of the material. Compost is a highly organic material which is the end product that is obtained from the transformation of different biodegradable waste products from water treatment plants, yard trimmings, and municipal waste. Studies done by Intharasombat (Intharasombat, 2005) on various combinations of depths and widths of compost treatments were found to be highly efficient in preventing shoulder cracking and the adjacent pavements. This was confirmed by digital photo analysis, visual observation and the moisture readings. This paper presents a summary of field performance related to volumetric moisture content and temperature characteristics of the compost amended soils as well as laboratory test data from cationic exchange capacity (CEC), organic content (OC), and pH studies. Data collected from the field showed moisture encapsulation in the amended soils. Laboratory measurements are used for the estimation of the life of the compost treatments. It was found that the life of the compost treatment determined by the periodic monitoring of the OC and CEC were around 4–5 years. Both laboratory and field characterization assisted in the enhancement of recycling application of the composts in pavement construction projects.
