The invention discloses asphalt pavement thickness measuring equipment for engineering supervision, which comprises an equipment counterweight seat, a mounting seat frame, a rocker arm lifting machinehead and an ultrasonic detection machine head, an electric lifting mechanism is fixedly mounted in the mounting seat frame, and a lifting stand column and a calibration measuring rod are fixedly mounted on the top surface of the mounting seat frame; the outer side of the lifting stand column is movably sleeved with a sliding sleeve base, a transverse rail limiting base is fixedly installed on oneside of the sliding sleeve base, an adjusting transverse rail is fixedly connected to the other side of the transverse rail limiting base, and the rocker arm lifting machine head is slidably sleevedwith one side of the adjusting transverse rail. According to the scheme, the ultrasonic detection machine head performs thickness measurement according to an ultrasonic pulse reflection principle, andwhen ultrasonic pulses emitted by the ultrasonic transducer head reach a pavement asphalt material and foundation interface through a measured pavement, the pulses are reflected back to the receivingmachine head; the thickness of the measured material is determined by accurately measuring the propagation time of ultrasonic waves in the asphalt material, the measurement mode is simple, and measurement is accurate.
本发明公开了一种工程监理用沥青路面厚度测定设备，包括设备配重座、安装座架、摇臂升降机头和超声波探测机头，安装座架的内部固定安装有电动升降机构，安装座架的顶面固定安装有升降立柱和校准测杆，升降立柱的外侧活动套接有滑动套座，滑动套座的一侧固定安装有横轨限位座，横轨限位座的另一侧固定连接有调节横轨，摇臂升降机头滑动套接于调节横轨的一侧。上述方案，超声波探测机头通过超声波脉冲反射原理来进行厚度测量，当超声波换能器器头发射的超声波脉冲通过被测路面到达路面沥青材料与地基分界面时，脉冲被反射回接收机头，通过精确测量超声波在沥青材料中传播的时间来确定被测材料的厚度，测量方式简单，测量精准。
