ASPHALT MIX DESIGN, QUALITY CONTROL AND TESTING FOR HOT CLIMATES ---PRE CONFERENCE PROCEEDINGS 3RD IRF MIDDLE EAST REGIONAL MEETING. TOWARDS BETTER ROAD PERFORMANCE, RIYADH, SAUDI ARABIA, 13-18 FEBRUARY 1988. 6 VOLUMES.

It has been found that conventional methods of mix design can sometimes result in materials which do not perform satisfactorily. In countries where extremes of temperature are experienced, the resultant failures can be relatively severe, often occurring soon after the road is opened to traffic. This paper examines the sometimes conflicting requirements which it is necessary to fulfill when designing an asphaltic mix. The design procedures are examined, and the void ratio concept is used to illustrate the effect of aggregate grading and also to emphasise the importance of obtaining a representative level of compaction at the design stage. Recommendations are made about additional testing techniques which could be used both for mix design and quality control purposes.(a) for the covering abstract of the proceedings see IRRD 817883.
