Project number 2: Sprickminimering - gradering & blandningsmetodik

Gradation and mixing teqniques - minimization of cracks in pavements

HMA is a composite material that mostly consists of rock material (stones). The approach is to investigate a new system developed in Florida by the Florida Pavement Group and investigate the advantages of the KGO-III-method to improve the properties of the mix. Main focus: Develop a laboratory mixer that allows full control of the material addition speed and continous measurement of the viscosity during mix. Development of a gradation based mixing method, new guidelines for mix design to optimize properties like cracking, rutting and so on.
