STABLE PAVEMENTS: QUESTIONS OF CONSTRUCTION

STANDFESTE FAHRBAHNBEFESTIGUNGEN; FRAGEN DER AUSFUEHRUNG

After fundamental consideration of the stability of bituminous layers the author discusses the components of resistance to deformation and the process of quantifying the influencing factors (marshall-test, tests with gyratory compactors, creep test). To improve the resistance to deformation of wearing- and basecourses and of the roadbase, allusion is made to increasing the viscous-resistance by means of harder binders, bitumen-plastic mixes, increase of the filler proportion, special fillers or asbestos and other additives and to the increase of the attrition-resistance by hard stone aggregate and crushed sand. Furthermore, discussion is held on the adjustment of the binder quantity to the voids content of the mineral aggregate, the influence of compaction on stability, the connection between voids content and deformation resistance and the influence of compaction technique and course thickness. /TRRL/
