Abstract

The invention discloses a bituminous pavement rolling analyzer, which comprises a left bearer, a right bearer, two guide rails connected between the left bearer and the right bearer, and a moving platform and a power transmission unit arranged on the guide rail; the outer cardboards are fixed at two sides of the moving platforms, a flat plate is provided between two outer cardboards and is positioned below the moving platform, a rolling wheel apparatus is arranged on the flat plate, an inner cardboard is fixed below the moving platform and the inner side of the outer cardboard, a hydraulic jack is provided between two inner cardboards, the hydraulic jack is arranged over the rolling wheel apparatus, and a displacement sensor is arranged on the flat plate. The bituminous pavement rolling analyzer can be used for simulating the construction on-site compacting status, and has effect for simulating the destroy of different driving speed vehicles on pavements, the anti-permanent deformation capability of an asphalt mixture is evaluated according to the measured rut depth; for cold regeneration asphalt mixture, and the strength at early stage of the cold regeneration asphalt mixture can be tested after core drilling and sampling.

Description

technical field [0001] The present invention relates to an analyzer, in particular to an asphalt pavement rolling analyzer, which can simulate the compaction conditions on the actual road construction site, use the determined compaction times to guide the required compaction times on the asphalt pavement construction site, and The performance of pavement is evaluated by simulating the damage effect of vehicle load on pavement. Background technique [0002] How to simulate the compaction condition of the road surface construction site in the laboratory, how to simulate the effect of actual vehicle load on the road surface, how to design the mix ratio according to the actual pavement performance, how to simulate the early strength of cold recycled asphalt mixture indoors, and how to characterize it The compactability of cold recycled asphalt mixtures is a concern of road workers. [0003] The failed engineering examples at home and abroad tell us that if the compaction degree...
