  • Method for calculating the optimum dosage of the two-component synchronous rejuvenator for aged SBS-modified asphalt
    Patent number: 12474320
    Abstract: The present invention precisely concerns the calculation method for the optimum two-component synchronous rejuvenator dosage for aged SBS-modified asphalt, including the following steps: (1) calculating the characteristic peak area ratio of unaged SBS molecular chain IB0 and unaged pure asphalt IB, aI0 and ARI0; (2) selecting four types of SBS-modified asphalt with different aging degrees and calculating their IBA, IB, aIA and ARIA; (3) adding the rejuvenator to above asphalts and calculating their post-rejuvenation BR, IB, aIR and ARIR; (4) establishing the regression equation between optimum rejuvenator dosage and characteristic peak area ratio requiring restoration due to aging; (5) as the given aged SBS-modified asphalt, substituting the characteristic peak area ratio requiring restoration into the equation to calculate the required optimum rejuvenator dosage.
