    Abstract: Ground-penetrating radar (GPR) can detect urban underground pipelines and image their spatial distribution. However, due to the interference of direct wave and ground reflected wave in radar profile, the detection accuracy of underground pipeline depth is low. In order to improve the reliability and accuracy of the interpretation of ground penetrat... Show More

    Abstract: The mixing uniformity of cement stabilized crushed stone includes two aspects, one is the uniformity of cement coating on aggregate, and the other is the uniformity of coarse and fine aggregate distribution. The uneven cement coating aggregate results in the segregation of base strength distribution. The uneven distribution of coarse and fine aggre... Show More
