Asphalt and recycled concrete pavement testing apparatus

Abstract

The invention discloses an asphalt and recycled concrete pavement testing apparatus which comprises an asphalt and recycled concrete pavement module, a loading traction device, a dip angle adjusting device, a measurement device and a rainwater device. The asphalt and recycled concrete pavement module includes an asphalt and recycled concrete layer, a recycled concrete type rubble layer, a cushion layer and an earth filling layer which are arranged from top to bottom. The loading traction device comprise a roller, a weight-bearing supporting plate, a connecting piece, a traction rope, an anti-collision plate, a guiding wheel and a variable-frequency and variable-speed motor. The dip angle adjusting device comprises a scale rotating wheel, an extensible support and a working platform. The measurement device comprises a thermometer, a flowmeter, a pressure meter, a horizontal displacement meter, a vertical displacement meter, a shake sensor and a rate meter. The rainwater device comprises a water guiding frame and a water distributor. The water distributor is arranged on the earth filling layer, and the earth filling layer is arranged on the working platform. Different situations are systematically researched, a corresponding relation between the situations and pressure, displacement and shake is established, technical support is provided for road project application of building waste, and meanwhile the utilization rate of the testing apparatus is improved.

Description

technical field [0001] The invention relates to the field of road engineering, in particular to an asphalt recycled concrete pavement test device. Background technique [0002] With the rapid development of society, light and fast low-speed vehicles, such as electric motorcycles and electric bicycles, are playing an increasingly important role in people's daily life and work, and the traffic volume in cities is also increasing. It is bound to cause high-speed and low-speed vehicles to run in separate lanes, and then put forward different requirements for the road surface when the vehicles are running. Although the construction waste is landfilled in the road after rough processing (mechanical crushing after stripping the steel bars), due to the lack of relevant technical specification support, the utilization rate of this large amount of idle sustainable resources in engineering practice is not high. high. Contents of the invention [0003] The purpose of the present inv...
