The utility model discloses a temporary service road in desert. According to the temporary service road in the desert, a roadbed is a thick macadam layer; the middle layer is a straw layer; the surface layer is a mixed layer; rectangular caulking grooves are formed downwards in the both sides of the roadbed respectively, and sand-straw mixture layers are arranged in the rectangular caulking grooves in a paving manner; side slopes of the rectangular caulking grooves are paved with straw lattices to form revetments. The temporary service road in the desert is wide in material range, low in cost and high in construction speed; the caulking grooves are formed in the both sides of the roadbed and filled with sand-straw mixtures, a constraining force is provided for a pavement, and thus the support strength of the pavement is enhanced and the service life of the pavement is prolonged; the side slope surfaces of the caulking grooves adopt the straw lattice revetments, and the functions of dyke strengthening and slumping prevention are realized, and thus the practical life of the pavement is prolonged; the three-layer structures are combined, and have the characteristics of being firm, economic, durable and the like; macadam, straws and mixed sand are arranged in a paving manner on the basis of the original road again, so as to form a new firm service road.
