The invention relates to a rapid repair and reinforcement treatment process of highway structure layer by grouting, comprising that following steps: uniformly drilling holes at the diseased parts of the road surface and 2 - 3 m outside the diseased parts at a hole spacing of 1.2 - 1.8 m according to the positions of cracks, subsidence and slurry pumping on the road surface, carrying out grouting to the structural layer of the road surface through a grouting device, and filling and compacting the gaps and voids of the structural layer by the slurry, so as to achieve the purpose of reinforcing the structural layer. The technology of the invention realizes the rapid repair of structural layer voids and voids caused by pavement cracks, subsidence and slurry pumping, and the reinforcement of pavement structural layer is quickly realized through inspection, hole arrangement, drilling, grouting and hole sealing, thus effectively realizing the rapid repair of pavement structural layer voids and voids, truly achieving the purpose of effectively controlling or inhibiting the development of subgrade diseases and preventing the occurrence of secondary diseases.
