Kono kadi 170-190°C firti ko ŋakkeende semmbe mawnde — golle nguleeki kala tonngoode ɓuuɓnde ina ɗaɓɓi fotde 30-40 MJ semmbe petroŋ. Asfalt ɓuuɓɗo (WMA) ina usta nguleeki ɓuuɓki haa 120-140°C, woni ustaare fotde 30-50°C. Ndee ustaare wonaa tan ‘usde nguleeki’ — ina wayla sifaaji rheological bitumen haa nde heɓa coftal gootal e gollal e nguleeki les. Juɓɓuɗo ummoraade e FangService ina heɓa ngool ustaare nguleeki rewrude e feere mum 3-in-1 (warm-mix + waylude + ɓuuɓnude).
