Engineering properties of road pavement materials

Road construction materials in common use in Perth include crushed granite rock base as a basecourse, crushed limestone as a sub-base and sand as a subgrade. These materials are typically specified in terms of particle size distribution, plasticity index, liquid limit, calcium carbonate content, Los Angeles Abrasion and similar physical and chemical properties. These materials are required to be compacted to various density criteria. Local Government Engineers will frequently face the decision of what to do about a road or street pavement constructed of material which is marginally outside specification limits. Does it matter if the dust ratio is 0.3 when the specification requires a minimum of 0.35? This paper discusses the various properties typically included in pavement material specifications and their probable (or improbable;) relationship with performance.
