This paper draws mainly on Chapter 3 of the final report of the European Commission COST 337 action where an overview was given, based on the work of Task Group 2c, on the granular materials that are used in unbound layers of road construction in Europe. The overview is based on information collected from all participating countries. Chapter 3 of the final report also reviews, based on the work of Task Group 2d, production, construction and quality control practices for road work in Europe but this paper gives an overview on the production practices. There are continuing requirements for more efficient use of road building materials, which are no longer as readily available as earlier. Environmental constraints are increasingly preventing the use of naturally occurring materials, which means that granular materials must be used with greater efficiency. Secondary materials, not previously used, should be increasingly used in road pavements. For the covering abstract see ITRD E118503.

Degradation of a variety of aggregate types, commonly used as ballast by the CN and CP railroads in Canada, and a non-ballast, were evaluated in the laboratory under different gradings, applied stresses, and density conditions. The ballasts were subjected to the one-dimensional and triaxial repeated loading stress states, encompassing some of the conditions likely to occur under tie-ballast track support systems. The results of these tests have demonstrated that the Mill Abrasion (MA), which is a measure of an aggregate's hardness, and the Los Angeles Abrasion (LAA), which measures the toughness of the aggregate, are the best indicators of degradation performance of an aggregate subjected to repetitive loads. The results also suggest that these material characteristics can be used to evaluate unbound aggregates for use in highway and airfield pavement structures as similar aggregate types are utilized in these systems as well. For the covering abstract see ITRD E118503.
