Abstract

The invention discloses an on-site detection device for a high-elasticity rubber asphalt composite crushed stone seal. The on-site detection device comprises a vehicle body, an electric rotating shaft, a water seepage instrument, a rolling device, an improved pendulum friction instrument and a drill core sampling device, and is characterized in that the electric rotating shaft, the water seepage instrument, the rolling device, the improved pendulum friction instrument and the drill core sampling device are positioned in the vehicle body, the electric rotating shaft is mounted at the top in the vehicle body, every two of the rolling device, the improved pendulum friction instrument and the water seepage instrument are mounted at an included angle of 120 degrees by taking the electric rotating shaft as a center, and the core drilling and sampling device is positioned on the other side of the vehicle body. According to the on-site detection device, the detection of four indexes of on-site skid resistance, skid resistance, density and void ratio of the high-elastic rubber asphalt composite chip seal can be realized, multiple functions are integrated, the efficiency and precision of performance detection are greatly improved, the defects of core drilling and sampling are overcome, and the device has important guiding significance for construction of the composite crushed stone seal.

Description

technical field [0001] The invention belongs to the field of on-site performance testing of road structures, and in particular relates to an on-site testing device for a high-elastic rubber asphalt composite gravel seal. Background technique [0002] In recent years, with the rapid development of my country's economy, the transportation industry has entered an era of rapid development. However, the construction of municipal roads in my country started relatively late, and the technical force is relatively weak. Under the combined effect of traffic load and natural environment, cracks, subsidence, and rutting appeared in advance only a few years after the road surface (especially asphalt pavement) was put into operation. Early failure phenomena such as oil flooding, etc., greatly reduce the performance of the pavement. The early damage of the road surface has developed into the biggest problem faced by road construction in our country, and the maintenance and repair work is i...
