2002 - UK - A Guide to the Design of Hot Mix Asphalt in Tropical and Sub-Tropical Countries

Overseas Road Note 19. This Road Note is aimed at engineers responsible for roads and gives guidance on the design, manufacture and construction of HMA pavement materials in tropical and sub-tropical climates. The HMA requirements are described for different traffic loading categories, including severely loaded sites such as climbing lanes. The procedures take into account the fact that many countries have limited facilities for designing bituminous mixes and therefore need to use commonly available or inexpensive equipment. The Road Note complements and, in many parts, also updates Overseas Road Note 31 (TRL, 1993 which gives recommendations for the design and construction of new road pavements but which also includes chapters on the design of pavement layers).
