%X The influence of compaction temperature on resistance under mono-tonic loading (Marshall) of Crumb-Rubber Modified (CRM) Hot-Mix As-phalt (HMA) was evaluated. The emphasis of this study was the applica-tion in Bogot¨˘ D.C. (Colombia). In this city the compaction temperature of HMA mixtures decreases, compared to the optimum, in about 30ˇăC. Two asphalt cements (AC 60-70 and AC 80-100) were modified. Two particle sizes distribution curve were used. The compaction temperatures used were 120, 130, 140 and 150ˇăC. The decrease of the compaction tempera-ture produces a small decrease in resistance under monotonic loading of the modified mixtures tested. Mixtures without CRM undergo a lineal decrease in its resistance of up to 34%.
