T19 specification sets out procedures for determining an optimised blend of aggregate and binders for the stabilisation of pavements.
The preparation of the aggregate and the preparation, curing and testing of test specimens mixed with cement, lime, foamed bitumen and/or bitumen emulsion are covered.
The purpose of T19 specification is to provide a standardised procedure to assist the pavement designer in determining the optimum type and quantity of binder(s) used for stabilising. It is the intention of this document to produce test specimens that closely replicate post construction field densities.
T19 specification also covers the production, sampling and strength testing of the stabilised aggregates in the field to confirm the improved properties.
The accompanying Notes are for the guidance of the laboratory staff who carry out mix design and quality assurance testing of modified and bound pavement materials, and for the guidance of supervising officers and design engineers commissioned to draft tender documentation and must not be included in contract documents.
