Abstract
A method of illuminating a pavement including mixing asphaltenes and a polymer in a solvent to form a solution. The method further includes coating the pavement with the solution and evaporating the solvent to form a coated pavement, followed by irradiating the coated pavement. Following the irradiation, the asphaltenes emit light, thereby illuminating the pavement. The asphaltenes are homogeneously dispersed in a polymer matrix in the coated pavement. The polymer has a formula (I) as follows, R1 and R2 are each independently an optionally substituted alkyl group with 1 to 20 carbon atoms or an optionally substituted aryl group with 1 to 20 carbon atoms, and n is 2 to 10000.
