Abstract
(EN)
An asphalt composition includes asphalt, a non-epoxidized oil chosen from flux oils, bio oils, recycled motor oils, liquid plasticizers, and combinations thereof, and a polyolefin. The polyolefin has a weight average molecular weight (Mw) of from about 1,000 to about 20,000 g/mol, an optional acid number of from about 5 to about 50 mg KOH/g, an optional saponification number of from about 10 to about 100 mg KOH/g, and a density of from about 0.92 to about 1 g/cm3. The asphalt composition has a performance grade of PG (52 to 88) and (-22 to -40), wherein (52 to 88) is an average seven day maximum pavement design temperature in degrees Celsius and represents deformation resistance and (-22 to -40) is an average one day minimum pavement design temperature in degrees Celsius and represents thermal cracking resistance, each as determined using AASHTO M320.

La présente invention concerne une composition d’asphalte comprenant de l’asphalte, une huile non époxydée choisie parmi les huiles de flux, les bio-huiles, les huiles de moteur recyclées, les plastifiants liquides, et leurs combinaisons, et une polyoléfine. La polyoléfine présente un poids moléculaire moyen en poids (Mw) d’environ 1 000 à environ 20 000 g/mole, un indice d’acidité facultatif d’environ 5 à environ 50 mg de KOH/g, un indice de saponification facultatif d’environ 10 à environ 100 mg de KOH/g, et une densité d’environ 0,92 à environ 1 g/cm3. La composition d’asphalte présente une qualité de performance PG (52 à 88) et (-22 à -40), où (52 à 88) est une température de conception de chaussée maximale moyenne en sept jours en degrés Celsius et représente la résistance à la déformation et (-22 à -40) est une température de conception de chaussée minimale moyenne en un jour en degrés Celsius et représente la résistance à la fissuration thermique, chacune telle que déterminée en utilisant la norme AASHTO M320.
