Background

Road surface drainage is an important aspect of road design. When water accumulates on the road surface, on one hand, water continuously permeates into the road surface structure to cause the cohesive force between the mixtures to be reduced, the viscosity of the materials is weakened, and further diseases such as the separation of the asphalt road surface mixtures, the cracking and the puring of the concrete road surface are easily caused, and the diseases are further developed into more serious road surface diseases under the action of long-term rolling of vehicles, so that the service performance and the service life of the road surface are shortened; on the other hand, the accumulated water can form a water film on the road surface, so that the friction between the running vehicle and the road surface is reduced, the dangerous phenomena such as skidding and the like are easy to generate, and the accumulated water forms water mist on the rear wheels of the vehicle, so that the visibility of the rear vehicle during running is reduced, and the occurrence rate of traffic accidents is greatly improved.

(2) The construction surface of road bed, road surface and slope surface often have macrostructures such as comparatively abundant local unsmooth, gap, and traditional grade bar test face is the elongated strip, easily receives the local structure influence to reduce its test accuracy.

(3) After the user of service tests the slope on the spot, need shoot, record, and the slope chi test surface is the slender strip, easily meets wind or other disturbances and emptys to damage fragile levelling tube structure, consequently need whole handheld instrument, inconvenient single completion survey overall process.
