随着公路交通事业的发展,公路等级的提高,交通量的增大,以及行车速度的加快,社会对道路行车的舒适性要求越来越高。路面平整度是评价行车舒适性的一个重要指标,用3米直尺测量路面平整度存在需要人员多、劳动强度大、测量速度慢、误差大、路上安全性差等缺陷,不适应当前大交通量路段测量的需要。车载式颠簸累积仪是测定路面平整度的一种简便高效的仪器,适于路面质量评价或路面养护管理系统应用,进行定期或不定期检测路面平整度或评定行车舒适性,它利用电脑记录,具有效率高、劳动强度低、安全快速、误差小
With the development of highway transportation, the improvement of highway level, the increase of traffic volume and the speeding up of traffic, the social demands for the comfort of driving on the road are getting higher and higher. Pavement roughness is an important indicator to evaluate the comfort of driving. Measuring the smoothness of the pavement with 3-meter ruler requires many personnel, labor intensity is large, the measurement speed is slow, the error is large, the safety on the road is poor and other defects do not meet the current large traffic volume Need for road measurement. Vehicle-mounted bump accumulator is a simple and efficient instrument for measuring road surface roughness. It is suitable for pavement quality evaluation or pavement maintenance management system application. It conducts periodic or irregular inspection of road surface roughness or evaluates driving comfort. It uses computer records, With high efficiency, low labor intensity, safe and fast, small error
