Bump Integrator

Product Code: EKE 9702

Roads are public utilities built for providing speedy, safe and comfortable ride to the road users. The safety and comfort of the users is adversely affected by poor riding quality of the roads. The riding quality, also termed as unevenness or roughness is an important parameter for evaluation of surface condition of roads. Roughness is the distortion in the road profile, which is of main concern to the road users. It is caused due to the inherent properties of materials and the construction techniques. This further deteriorates through permanent deformation of the layers in the pavement structures.
The roughness of the pavement forms an important input to any Pavement Management System (PMS) in deciding upon the maintenance strategies to be applied on road surface. The riding quality is generally measured by response type instruments, which are either towed or mounted on the vehicle itself.
Bump Integrator also known as Roughometer or Automatic Road Unevenness Recorder gives quantitative integrated evaluation of surface irregularities on an digital counter / LCD screen. It comprises of a single wheeled trailer, with a pneumatic tyre mounted on a Bump Integrator
chassis, on which an integrating device is fitted. The machine has a panel board fitted with two / four sets of digital counters for accounting the unevenness index value.
