Laboratory Evaluation of Asphalt Mixture Performance Using Composite Admixtures of Lignin and Glass Fibers

Moisture damage and low-temperature cracking are common distresses experienced by road pavement. Different types of modifiers, such as fibers, can be used to improve the quality asphalt pavements. In this paper, lignin glass fiber were selected additives enhance water- stability mixtures. The main objective study was evaluate composite effects adding a bituminous mix using experimental methods. Marshall immersion, freeze–thaw splitting, three-point bending tests applied efficiency (and/or) modified mixes with regard moisture low temperature. Four kinds mixtures, namely, control (C), (L), (G), (LG) evaluated. results showed that addition 0.30% water stability, improved significantly. With fiber, mixtures better resistance thermal cracking, while resulted in greater susceptibility. admixture more effective than either or modifying performance. This clarifies great beneficial effect mixture industry.
