Abstract
News editors obtained the following quote from the background information suppli ed by the inventors:“With the development of modern road networks, the maintena nce and management of pavement hasbecome increasingly prominent. Conventionally , manual detection has been used to evaluate road conditions,such as holes and cracks in roads. In some conventional road condition management approaches, ane ngineer visually checks the number of cracks in the road and calculates a crack ratio, a general estimatefor linear feet of cracks per unit area, for each port ion of road. Later, a crew size of 4 to 7 people workto manually seal cracks fo r several lane miles each day. This sealing is inconsistent, as workers get tired and must make quick decisions on what to seal, and dangerous, as workers are e xposed to traffic andhave to work in close proximity with scalding hot sealant. These approaches suffer from low efficiency andinterference of subjective fact ors, particularly when large road networks are considered.
