Pavement Data Analysis Service (PDAS)
Our pavement performance analysis service helps road operators make data-driven decisions by providing performance projection based on inspection data. For the data analysis, we evaluate pavement performance with stochastic model and statistical analysis. This approach doesn’t require a long time series of data, like a regression analysis. We estimate the average pavement performance deterioration rate and remaining lifetime. In addition, we compare pavement performances in several situations including roadway sections, pavement structure, material, traffic and climate.
- Only two time-series of data are required.
- Various comparisons of pavement performance; section, pavement structure, material, traffic and climate
Pavement deterioration evaluation module analyzes the pavement deterioration and predicts future deterioration based on two-time series data such as pavement condition data and maintenance history. The estimation of deterioration is performed by using Markov Transition Probabilities Theory.
The strategic budget planning module simulates the budget requirements for three scenarios: (1) non constraint, (2) budget constraint, and (3) risk constraint. The output of this module is very useful in establishing road maintenance strategies.

Pavement condition survey data and deterioration performance data are displayed on the digital website road map.
Quality Improvement Service for Pavement Data Collection
Backed by over 30 years of data collection experience, we can support engineering companies and data collection vendors by collecting pavement performance data accurately. We own and operate a high-speed pavement data collection vehicle that obtains pavement distress images, longitudinal/transverse profiles and 3D mapping images with geospatial data. Our vehicle performs all six functions reliably and safely at 60 mph without interfering with traffic flow. It will lower your pavement management and life cycle costs.
3D Pavement Rehab Design Service/Software
Our 3D Pavement Rehab Design Service helps engineering companies design pavement rehabilitation projects intended to improve ride quality and storm water drainage. We have developed a dedicated software package that performs this analysis efficiently.
MATERIALS and more
Water Jet Robot / Hydrodemolition
Our water jet robot removes deteriorated concrete even in narrow spaces between bridge decks and substructures without causing any damage to the remaining structure. After the removal, low-viscosity repair materials are applied. This robot helps owners extend the life of their bridges.
- Removes concrete with ultrahigh water pressure
Useful in narrow-spaced or longitudinal work
(Reaches 1,000mm with a minimum clearance of 20mm in one movement)
- Remote operation guarantees worker safety

Pavement/Bridge Repair Materials
Our repair materials are for road operators and M&R contractors who want to repair their roads effectively and thoroughly. Unless road owners conduct repairs with the right materials, at right time using the right methods, the deterioration of concrete, steel and asphalt could accelerate, leading to earlier, more expensive road replacement.
