STABILIZATION WITH LIME: STABILIZATION OF WET COHESIVE SOIL WITH LIME. V 2

STABILISATION A LA CHAUX. TRAITEMENT DES SOLS COHESIFS HUMIDES PAR LA CHAUX. V.2

Cohesive soil stabilized with lime and compacted becomes gradually cemented. This cementation which is responsible for the long-term effects of the lime, improves the mechanical characteristics of the mixture. For a given soil there exists a "suitable" proportion of lime which combines economy and strength. This proportion is generally between 4 and 8% fat quick lime. It is determined by uniaxial compression tests on mixtures containing increasing proportions of lime, compacted at the same dry bulk density with the same moisture content and cured for 7 days at 40 deg C. The development of the mechanical properties is slow at ordinary temperatures. It is inhibited by the presence of organic matter in the soil. The nature of the organic matter is far more important than its quantity. The durability of soil stabilized with lime (e.g. sufficient resistance to immersion, frost and freezing-thawing cycles) is obtained only after several months of age at 20 deg C (approximately 6 months). This is the weak point of stabilization with lime. However observations made on a non-protected lime-stabilized site showed that laboratory tests seem to be too strict for evaluating the satisfactory in-situ behaviour of lime stabilized layers in the presence of frost.
