MATERIALS IN BITUMINOUS MIXTURES

LOS MATERIALES EN LAS MEZCLAS BITUMINOSAS

The materials forming bituminous mixtures are examined. The aggregates may be divided between natural and artificial aggregates produced in the production plant. The author analyses the influence of the types of rock and the process of crushing from the point of view of the physico-chemical, geometrical and mechanical characteristics. The most commonly used binders are bitumens, which are characterized by three typical tests: penetration tests, ring and ball tests and impact tests. The tar used for roads is produced by treating coal tar and is characterized by its equi-viscous temperature; its adhesion to aggregates is superior to that of bitumen. On other occasions, use is made of mixtures of bitumen and tar and additional polymer binders, such as, for example, the bitumen-polymer of high molecular weight, epoxy bitumen which is at the research stage and particularly the tar-polymers (vinyl, epoxy, polyurethane). The research deals with binders without bitumen or tar (cork is used) and mixtures of fine sand and epoxy resin as elastic support of the aggregates. /TRRL/
