Pavement lossless compaction degree measuring device and compaction degree measuring method
The invention relates to a road surface lossless compaction degree measuring device and a compaction degree measuring method.The road surface lossless compaction degree measuring device comprises a device support and further comprises a center compaction hammer and an annular compaction hammer located on the periphery of the center compaction hammer, the center compaction hammer and the annular compaction hammer are independently arranged, and the bottom of the center compaction hammer is provided with a center contact part in contact fit with a road surface; the bottom of the annular compaction hammer is provided with an annular contact part which is located on the periphery of the center contact part and is in contact fit with a road surface, the device support is provided with a center impact hammer and a peripheral impact hammer which can be driven by a lifting mechanism to increase the height, and the bottom of the center impact hammer is provided with a first impact part used for impacting the upper end of the center compaction hammer; and the bottom of the peripheral impact hammer is provided with a second impact part which is used for synchronously impacting the annular compaction hammer when the first impact part impacts the central compaction hammer. The technical problem that in the prior art, pit digging, sand filling and sand collecting need to be conducted on the road surface, and consequently the labor intensity of compaction degree measurement is large is solved.
本发明涉及一种路面无损压实度测量装置及压实度测量方法，包括装置支架，还包括中心击实锤和位于中心击实锤外围的环形击实锤，中心击实锤、环形击实锤彼此独立设置，中心击实锤的底部具有与路面接触配合的中心接触部，环形击实锤的底部具有位于中心接触部外围的与路面接触配合的环形接触部，装置支架上设置有在提升机构驱动下能够提升高度的中心撞击锤和外围撞击锤，中心撞击锤的底部具有用于撞击中心击实锤上端的第一撞击部，外围撞击锤的底部具有用于在第一撞击部撞击中心击实锤时同步撞击环形击实锤的第二撞击部。本发明解决了现有技术中需要在路面上挖坑、填沙和收沙而导致压实度测量劳动强度大的技术问题。
