Deformation Of Granular Pavement PowerPoint PPT Presentations

Compaction of granular pavements using compaction equipment induces high stresses and strains in the materials being compacted. The distributions of these stresses are dependent on the properties of the compaction plant as well as the mechanical properties of the granular materials. The stresses help compact the granular materials at certain depths, but could also loosen the materials at some locations. Understanding of this micro behaviour of the granular materials is fundamental to improving the performance of granular pavements, and understanding and avoiding problems such as early rutting. The purpose of our investigations is to understand where, when and how the loosening may be happening, and consider measures that avoid this. To minimize early rutting, an innovative approach such as pre-stressing granular material will be tested.

Asia Pacific Bitumen Market size is expected to cross USD 60 billion by 2027. Significant expansion of construction and infrastructure industry in Asia Pacific is propelling the demand for efficient construction materials in the region. One such material is Bitumen, which is a complex hydrocarbon and is largely used for road construction. It finds extensive application as a binder in road construction materials such as stones, aggregates, etc. Its superior natural properties make it useful in waterproofing and adhesives industries also.
