• Abstract:
  In this project many different short-range sensors used in pavement micro and macro texture measurement were investigated. Two categories of sensors were researched: light wave-based sensors and electromagnetic (EM) wave-based sensors. Light wave-based sensors include laser triangulation with feedback control. EM sensors include microwave and millimeter wave macro texture detectors. The laser sensor was prototyped and lab tested. Limited field tests were performed. This prototype laser sensor includes laser transceivers, data acquisition system, and associated software. Test results show that the laser sensor is able to measure both macro and micro textures of the pavements. This report briefly discusses basic operation principles of the laser system, implementation details and software development. The EM sensors are based on microwave scattering from a rough surface. Macro texture information can be extracted from mathematics computation using data measured by the EM sensor. Several frequency bands were investigated including 10 GHz band, 35 GHz band, and 90 GHz band. The test results show that microwave and millimeter waves are very sensitive to pavement textures. Prototype EM sensors were constructed and lab tested. Theoretical discussions of the EM sensor are given in this report. Several tested cases are also presented.
