ROAD PAVING METHOD
The present invention relates to a road paving method enabling one to provide an asphalt paving material layer in which both excellent stability and stress relaxation can be made compatible with each other, the method includingStep 1: a step of mixing asphalt, a thermoplastic elastomer, a polyester, and an aggregate to obtain an asphalt mixture, andStep 2: a step of laying the asphalt mixture obtained in Step 1 on a road, thereby forming an asphalt paving material layer, whereinthe polyester has a softening point of 90°C or higher and 140°C or lower and a glass transition point of 40°C or higher and 80°C or lower, anda ratio of the polyester is more than 17 parts by mass and 50 parts by mass or less based on 100 parts by mass of the asphalt.
