SSI Grind Optimizer Software Solution

At a Glance

SSI’s Grind Optimization software automates the cumbersome, time consuming process of determining locations for corrective grinding to meet specified thresholds for IRI, MRI and ALR (Areas of Localized Roughness). As the only commercial alternative to FHWA ProVal software’s “Smoothness Assurance Module,” SSI’s Grind optimizer offers a much faster, more thorough and efficient grind simulation solution.  Dual wheel track data can be loaded and simultaneously processed according to user configurable thresholds for IRI, MRI and ALR corrective grinding simulations. Most common commercial grinder settings are pre-configured. Projected locations for corrective work can be used with SSI’s GPS based profile navigation tool for precision guidance to the grinding locations without marking the pavement. Sample screens and more details are below.

Features & Benefits

 

Fast, Efficient Grinding Plans for Achieving Smoothness

  • Works with any PPF data or RSD data from SSI devices
  • Determine grind locations per your project’s full smoothness specification (IRI or MRI)
  • Determine corrective grinds based on IRI short continuous, IRI long continuous, IRI or MRI fixed interval
  • Optimize grinds per the operating cost of grinding
  • Use configurable dimensions for commercially available grinders (e.g., G-38, PC-390, PC-1500, PC-4500, PC-6000)
  • No more simulated feathering issues at the grind limits
  • Limit the cut depth to a restrictive value
  • Export the cut depths per specified interval

 

Improvements Over Other Software (ProVal)

  • Create cut depth report for machine control
  • Determine optimized corrective grinding for long continuous and fixed interval specifications
  • Eliminate manual trial-and-error iteration
  • SSI Reports MRI post-grind results
  • Optimization inputs for grinds to be a minimum length or minimum distance between locations 
  • Add more than 2 passes over same location

 

Optimization Works with CS7900 On-Grinder GPS Tool

  • Navigate to grind locations without paint marks
  • Utilize a precise GPS receiver with an optional subscription, accurate to within 0.1 meter (3.9 inches)
  • Active display of exact locations to begin and end grinding; also shows height of trace peaks
  • Display current position by GPS and linear distance to next and previous grind locations
  • View single or dual graphs (profile, continuous IRI)
  • Use the profile data and GPS collected with an inertial profiler or profilograph system
  • Grinding locations can be merged longitudinally and transversely
  • Data can be transferred to the grinder in under 5 minutes by USB or Wi-Fi connection
  • Hardware can be mounted on any diamond grinder or cold planer
  • Hands-free use of software during grinding operation
  • Large touchscreen utilizing Panasonic Toughbooks
  • Portable hardware can be used on multiple pieces of equipment or in your vehicle
