Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an asphalt based composition which accelerates the evapo ration of an organic solvent and has good adhesion into pavement cracks, and a road repairing method using the composition. SOLUTION: Pavement cracks are repaired by adding gasoline to straight asphalt to form a primary composition which is liquid at normal temperatures, mixing a blowing agent therewith to form a secondary composition 3, injecting the secondary composition 3 into the inside of a cracked portion 2 of the pavement 1, then laying a heated asphalt based paving material 4 on the cracked portion 2 from above to generate fine air bubbles 5 by heating the secondary composition 3, discharging the gasoline component with the air bubbles 5 outwardly to allow the secondary composition 3 to exhibit necessary adhesion, allowing the secondary composition 3 to adhere to the inner walls of the cracked portion 2 and the asphalt based paving material 4, and curing the secondary composition 3 and the asphalt based paving material 4.
