Asphalt
Few-layer graphene GUP® reduces the aging of asphalt and enhances the mechanical and physical properties
Asphalt, a pavement material, will be aged by many factors, such as heat, light, and oxygen during the high-temperature production and natural environment during service. Aging makes the asphalt binder become harder, leads to early damage, and reduces the service life span of the pavement. Therefore, to prolong the service life span of an asphalt pavement, it is important to improve the anti-aging performance of the asphalt. After aging, the asphalt molecular weight will be increased or associated irreversibly to form macromolecules by absorbing oxygen, the asphalt colloid structure will, therefore, be changed, decreasing the asphalt pavement performance.
