摘要
按照《公路路基路面现场检测规程》(JTGE60-2008)试验方法,结合工程实际,经过试验室的大量试验,建立路面混凝土抗弯拉强度与超声波速值、回弹值的测强曲线方程,并用取芯法对超声回弹综合法检测路面混凝土抗弯拉强度的结果进行验证。验证结果表明:超声回弹综合法准确性高,能够满足工程检测的需要。
Applying the test methods prescribed in ＂Field Test Methods of Subgrade and Pavement for Highway Engineering＂（JTG E60-2008）, combining with the engineering project practice, after a great amount of tests in the lab, the strength-measuring curve equations for concrete pavement＇s flexural strength, ultrasonic the test result inspection combined method owns a speed and rebound value have been confirmed. Cores method is applied in and verification. Inspection and verification result shows ultrasonic-rebound high veracity and meets the engineering testing requirements.
