DEVELOPMENTS IN HIGHWAY PAVEMENT ENGINEERING--1. CHAPTER 3--ASPHALT MIX DESIGN

This chapter considers the two types of dense asphaltic mixes in common use for road surfacings. These are gap-graded mixes (such as hot rolled asphalt) and continuously graded mixes (such as asphaltic concrete). In both cases, the effect that the various components can have on the performance of the complete mix is first discussed, and a suitable design procedure is then described. In the case of the gap-graded mixes the procedure described, which uses parts of the Marshall test, is flexible in that it can be used to produce either conventional hot rolled asphalts to BS 594, or less conventional mixes outside the limits of that specification. For continuously graded mixes, two versions of the Marshall test are described. Desirable values of the performance parameters are given, although for the gap-graded mixes it is suggested that field trials are needed to confirm these. /Author/TRRL/
