大量的实验和理论研究表明，路面状况的好坏影响着路面的附着性能；路面的附着性能又影响着车辆的运行安全。因此，搞好公路养护，加强路政管理，是改善路面状况，提高路面的附着性能，保证行车安全的重要措施。
A large number of experimental and theoretical studies have shown that the condition of the pavement affects the adhesion performance of the pavement. The adhesion of the pavement also affects the running safety of the vehicle. Therefore, doing a good job of road maintenance and strengthening the administration of the road are important measures to improve the condition of the road, improve the adhesion of the road and ensure the traffic safety.
