This document discusses using an autonomous robot named the P3-AT to measure pavement roughness by collecting longitudinal profiles and computing the International Roughness Index (IRI). The P3-AT was equipped with sensors including a laser for vertical displacement measurements. A preliminary test of the P3-AT on a smooth 50m indoor pavement section produced an average IRI of 1.09 m/km, comparable to results from a commercial profiler. Future work involves integrating GPS and inertial systems to allow the P3-AT to perform practical pavement inspections autonomously outdoors.

IICTG will serve as a source of knowledge, forum for discussion, and provider of training on technologies like intelligent compaction, thermal profiling, 3D modeling, machine guidance, and building information modeling. IICTG's inaugural meeting was held in Portugal in 2016 and future biannual conferences are planned in the US, China, and Portugal. The group is led by founders from the US, Portugal, and China and has steering and technical committees to advance its objectives of information exchange and research collaboration.
Practical implementation of automated joint fault measuerment
This document discusses automated fault measurement of concrete pavements based on pavement profile data. It presents challenges in measuring faults accurately using profiles, including joints with spalls or cracks. The revised AASHTO R36 standard for evaluating faulting requires validating automated measurements with physical devices at joint spacings. The ProVAL software identifies joint locations in profiles using various detection methods and computes faults by fitting profile slices on each side of joints. Widespread use of automated fault measurement can help agencies meet federal reporting needs in a consistent, efficient manner.
Fundamentals of Intelligent Compaction
It describes the fundamentals of intelligent compaction, including equipment, measurement system, software, and etc.
Intelligent Construction - an overview
This document provides an overview of intelligent construction technologies. It discusses technologies that can collect, analyze, and use information to make decisions during construction. These include computer-aided construction modeling, high precision surveying using GPS and LIDAR, smart material production using automated monitoring and control, machine guidance using 3D models and GPS, quality monitoring through intelligent compaction and smoothness testing, and construction/data management with 3D/4D modeling and automated data linking between field and office. The benefits of these intelligent construction systems technologies include improved quality, reduced schedules, more effective inspections, and integrated construction and materials data.
Quantify Impact of JCP Curl/Warp on Smoothness
This document summarizes a study on quantifying the impact of jointed concrete pavement curling and warping on pavement unevenness. It outlines methods for measuring curl and warp through inertial profiling at different times of day and seasons. A new 2GCI (2nd generation curvature index) method is presented to characterize slab curvature. A RoCK (curvature-impact-roughness) system was developed to assess how curvature impacts roughness. Different pavement sections were classified based on whether curvature dominates or mildly affects roughness. The implications for timing acceptance testing and practices to avoid curl and warp are discussed.

This document summarizes intelligent compaction technology, including different types of intelligent compaction rollers and in-situ testing methods. It discusses key findings from field demonstrations of intelligent compaction for hot mix asphalt and soils/subbases/stabilized bases. Future work areas are identified such as improving data management, standardizing measurements, and linking intelligent compaction data to long-term performance. Benefits of intelligent compaction include improved density, efficiency, and quality control/quality assurance.
