Description

Self-propelled road surface flatness tester

Technical Field

The utility model relates to a road detection technology field, concretely relates to self-propelled road surface roughness tester.

Background

Road Surface flatness (Road Surface Roughness) refers to the vertical deviation of the Surface of a Road Surface from an ideal plane. The pavement evenness is an important index in pavement evaluation and pavement construction acceptance, and mainly reflects the evenness of a pavement longitudinal section profile curve. When the profile curve of the longitudinal section of the road surface is relatively smooth, the road surface is relatively flat or the flatness is relatively good, otherwise, the flatness is relatively poor. Good pavement requires good pavement flatness. The flatness of the road surface is one of the main technical indexes for evaluating the quality of the road surface, and is related to the safety and comfort of driving, the impact force on the road surface and the service life, the uneven road surface can increase the driving resistance, and the vehicle can generate additional vibration. This vibration can cause bumps in the ride, affect speed and safety of the ride, and affect the ride stability and comfort of the passengers. At the same time, the vibration effect also exerts an impact force on the road surface, which aggravates damage to the road surface and automobile parts and wear of tires, and increases oil consumption. In addition, for the area located in the water network, uneven road surface can accumulate rainwater, and the water damage of the road surface is accelerated. Therefore, in order to reduce the vibration impact, increase the driving speed and improve the driving comfort and safety, the road surface should maintain a certain flatness. Factors influencing the pavement evenness can relate to the design, construction, natural conditions and other aspects, and the excellent pavement evenness is guaranteed by means of excellent construction equipment, an accurate construction process, strict construction quality control and frequent and timely maintenance. Factors influencing the flatness of the asphalt concrete pavement mainly comprise: uneven settlement, a paving process, a rolling process, transverse seam treatment, mix proportion design, lower bearing layer diseases and the like. The flatness directly reflects the driving comfort of the vehicle and the safety and service life of the road surface. The detection of the pavement evenness can provide important information for decision makers, so that the decision makers can make optimization decisions for pavement maintenance, overhaul and the like. On the other hand, the detection of the pavement evenness can accurately provide information of the pavement construction quality, and an objective index for quality evaluation is provided for pavement construction.

When the eight-wheel road surface flatness tester detects the road surface flatness, a car is used as a tractor to pull the eight-wheel road surface flatness tester to run along a vehicle wheel track belt/track at a speed of 5-15Km/h, the eight-wheel road surface flatness tester automatically collects concave-convex deviation values of the road surface every 10cm in the running process, namely gap values of the middle positions of three meters of straight scales are used, then the gap values are calculated every 100 meters, the obtained standard deviation is used as a road surface flatness index, and data are automatically recorded, stored, calculated and analyzed. When the existing eight-wheel road surface flatness tester detects the road surface flatness, a car is required to be used as a tractor and a manually driven vehicle for detection, the detection result accuracy caused by the reasons that the running speed of the vehicle cannot meet the requirement, the vehicle cannot run at a constant speed, the vehicle cannot run along the wheel track/track of the vehicle and the like is poor, and the potential safety hazard is caused by long driving time of personnel.
