Abstract:

In this paper a simplified mechanical method for estimating the shrinkage crack spacing and width in a base layer is presented. The base material is cement treated mix granulate produced by using recycled crushed concrete and masonry aggregates (CTMiGr). This method is based on material properties of CTMiGr as measured in the laboratory and the average climatic conditions recorded in the Netherlands. The calculated crack pattern showed to be comparable to the crack spacing observed in the field. The masonry content is a key factor determining the shrinkage crack characteristics. With increasing the masonry content, the crack spacing becomes larger and the width of the primary cracks dramatically decreases. Compared to the effect of the cement content and the moisture content on the shrinkage crack pattern, the influence of the degree of compaction is less.
