إن رص الخلطات الإسفلتية الساخنة (HMA) عند درجات حراة منخفضة أو خلطها في المجابل عند درجات حرارة عالية يشكل مصدر قلق دائم للباحثين , حيث يؤدي الرص والخلط عند درجات حرارة غير مثالية إلى الحصول على نتائج عكسية والتي تؤثر سلباً على خصائص الخرسانة الإسفلتية وتؤدي لحدوث مشاكل بالرصف .
Compacting hot mixes asphalt (HMA) at low temperatures or mixing it in the asphalt at high temperatures is a constant source of concern to researchers, as compacting and mixing at non-ideal temperatures leads to adverse results, which negatively affect the properties of asphalt concrete and lead to problems paving.
