4. Products covered (HS or CCCN where applicable, otherwise national tariff 
heading. ICS numbers may be provided in addition, where applicable):  Road 
construction materials (ICS code(s): 93.080.20)  
5. Title, number of pages and language(s) of the notified document:  DEAS 1207 
2024, Asphalt paving mix design — Code of practice; (78 page(s), in English)  
6. Description of content:  This Draft East African Standard provides guidelines on the 
design of asphalt paving mixtures to be used for general a sphalt pavements.  
These guidelines are applicable to the design of Hot Mix Asphalts (HMA) produced from 
new (virgin) asphalt materials and Reclaimed (Recycled) Asphalt Materials in the design 
process.  
NOTE The guidelines for mix design given in Clause 7 are based on commonly used asphalt 
design methods mainly Superpave HMA Mix Design System, Marshall Method of asphalt 
mix design and Hveem method of asphalt mix design.  
7. Objective and rationale, including the nature of urgent problems where 
applicable:  National security requirements; Prevention of deceptive practices and 
consumer protection; Protection of human health or safety; Protection of the 
environment; Quality requirements; Harmonization; Cost saving and productivity 
enhancement
