Rutting Performance of Semi-Rigid Base Pavement in RIOHTrack and Laboratory Evaluation

Through a simple performance dynamic modulus test (SPT), standard rutting test, Hamburg French and asphalt pavement analyzer the resistance of mixtures in middle lower courses three semi-rigid base Beijing full-scale track road China was evaluated. The results show that can be greatly improved by using low-grade asphalt, especially 30# asphalt. SBS modified is also better. SPT indirectly characterize mixture. laser detection vehicle 3 m ruler grade has significant impact on pavement. Compared with 70# used courses, structure more than 20%. result APA closely results, which an optimal method for evaluating research provide theoretical basis reference rational design evaluation
