Shrinkage Performance of Lime-Fly Ash Stabilized Crushed Stone
In order to study the effect of several factors on the shrinkage performance of lime-fly ash stabilized crushed stone, temperature shrinkage coefficients and dry shrinkage coefficients of mixtures with different gradations, lime and fly content and age were measured. Results indicate that mixture with a stone-on-stone contact has better shrinkage-resistance performance; For the same gradation, both dry shrinkage coefficient and temperature coefficient become improved with lime-fly content increasing; when the lime-fly content is the same, temperature shrinkage coefficient increases with longer age; Results of analysis of variance show that to the temperature shrinkage coefficient, the effect of age and lime and fly content are important, and the latter is greater. To the dry shrinkage coefficient, gradation and lime and fly content are important factors, and the former is greater.
