<P>PROBLEM TO BE SOLVED: To provide an antiadhesive agent for an asphalt mixture, which exhibits high antiadhesive and exfoliative effects to the asphalt mixture, and even the water-diluted one of which is stable at normal or low temperature. <P>SOLUTION: The antiadhesive agent for the asphalt mixture contains 32-94 mass% of the compound (A) shown by formula (1): R<SP POS="POST">1</SP>O-((EO)<SB POS="POST">m</SB>(AO)<SB POS="POST">n</SB>)-R<SP POS="POST">2</SP>, 5-60 mass% of the compound (B) shown by formula (2): R<SP POS="POST">3</SP>O-((EO)<SB POS="POST">k</SB>(PO)<SB POS="POST">l</SB>)-R<SP POS="POST">4</SP>and 1-8 mass% of liquid paraffin (C) which has 1-40 mm<SP POS="POST">2</SP>/s kinematic viscosity at 40°C and is a liquid at -10°C. In formula (1), R<SP POS="POST">1</SP>and R<SP POS="POST">2</SP>are each a methyl group or the like; m is 1-5; n is 1-5; AO/(EO+AO) is 20-75 mass%; EO may be bonded to AO in a blocked or random state. In formula (2), R<SP POS="POST">3</SP>is an isodecyl group or the like; R<SP POS="POST">4</SP>is a hydrogen atom or the like; k is 2-30; l is 0-20; PO/(EO+PO) is 0-50 mass%; EO is bonded to PO in a blocked state. <P>COPYRIGHT: (C)2013,JPO&INPIT |
