Abstract In this study a software-based modeling study that can accommodate the needs to determine the surface conditions of pavement, plan for handling road damage, and predict the remaining life of pavement services. The data used in this study are primary data from the Pavement Condition Index survey on a Yogyakarta–Magelang road segment Magelang, KM 10+000-KM 11+000, and secondary data, in the form of Surface Distress Index data, International Roughness Index data, and traffic data obtained from the National Road Planning and Supervision of the Special Province of Yogyakarta. The software used in this study is Borland Delphi 7.0 software. From this study, a software called Modrova was produced. This study shows that the Modrova software is valid to use because the resulting error is relatively small. Keywords: road surface conditions, road damage, road pavement, remaining life of road pavement  Abstrak Pada studi ini dikaji suatu pemodelan berbasis perangkat lunak yang dapat mengakomodir kebutuhan untuk menentukan kondisi permukaan perkerasan jalan, merencanakan penanganan kerusakan jalan, serta mempre-diksi sisa umur layanan perkerasan jalan.

A avaliação do perfil longitudinal em pavimentos de Concreto de Cimento Portland é de suma importância, tanto para a o controle da qualidade de serviços executados durante períodos de obra, quanto para monitorar a evolução da irregularidade ao longo de sua vida de serviço. O Perfilômetro Inercial a Laser apresenta grande potencial de uso para este fim, pois proporciona elevada produtividade e resolução menor que 5 mm (a depender da velocidade de uso). Nesta pesquisa foram tomados como caso de estudo 09 segmentos da rodovia BR-101/SE, com níveis diferentes de qualidade de perfil. Os perfilogramas e resultados de IP (índices de perfis) e IRI (international roughness index) obtidos com o Perfilômetro Inercial a Laser e Perfilógrafo Califórnia (Equipamento de referência) foram comparados para todos os segmentos estudados. Para o pavimento em estudo, concluiu-se que os perfilogramas obtidos representaram de forma graficamente análoga os defeitos que interferem na irregularidade longitudinal. Na comparação para os índices IP e IRI resultantes dos dois equipamentos, os resultados apresentaram-se estatisticamente semelhantes. Portanto, observa-se que o equipamento Perfilômetro Inercial a Laser representa bem as características dos defeitos que influenciam na irregularidade longitudinal dos pavimentos de Concreto de Cimento Portland. Ele pode ser utilizado para medições do Perfil Longitudinal e obtenção dos índices de irregularidade para aceitação de obras e monitoramento da irregularidade longitudinal nas rodovias em operação.

The Relationship

Abstract An assessment of road surface conditions is needed to determine an appropriate road evaluation program. One of the parameters used is the International Roughness Index or IRI. Currently, technological developments encourage the use of smartphone applications as a tool to determine the value of IRI. Comparisons between IRIs obtained using tools, such as roughometers, and IRIs obtained from software applications have not been made. The purpose of this study was to analyze the relationship between the results of the measurement of the roughometer and the results of the Android application Roadbump Pro. This research was carried out on the Sam Ratulangi Road in Palu City, with a segment length of 600 meters and analyzed per 100 meters. The results of this study indicate that smartphone applications provide good IRI measurement results, so they can be used in road stability assessments. In addition, the type of survey vehicle did not have a significant effect on IRI measurements. Keywords: smartphone, International Roughness Index, roughometer, Roadbump, road stability  Abstrak Penilaian kondisi permukaan jalan diperlukan untuk menentukan program evaluasi jalan yang tepat. Salah satu parameter yang digunakan adalah International Roughness Index atau IRI. Saat ini, perkembangan teknologi mendorong penggunaan aplikasi smartphone sebagai alat bantu untuk menentukan nilai IRI. Perbandingan antara IRI yang diperoleh dengan menggunakan alat bantu, seperti roughometer, dan IRI yang diperoleh dari aplikasi perangkat lunak belum dilakukan. Tujuan penelitian ini adalah menganalisis hubungan antara hasil pengukuran alat roughometer dan hasil aplikasi android Roadbump Pro. Penelitian ini dilakukan di ruas Jalan Sam Ratulangi di Kota Palu, dengan panjang segmen 600 meter dan dianalisis per 100 meter. Hasil penelitian ini menunjukkan bahwa aplikasi smartphone memberikan hasil pengukuran IRI yang baik, sehingga dapat digunakan dalam penilaian kemantapan jalan. Selain itu, jenis kendaraan survei tidak memberikan pengaruh yang signifikan terhadap pengukuran IRI. Kata-kata kunci: smartphone, International Roughness Index, roughometer, Roadbump, kemantapan jalan

Special Provision

In the summer of 1996 the Virginia Department of Transportation (VDOT) initiated the pilot of a new special provision regarding the smoothness of asphalt pavement surfaces. This special provision is based on the international roughness index (IRI) and is administered with a laser-equipped South Dakota–style inertial road profiler. A critical assessment of the nontraditional equipment and methods used to administer the special provision is provided. Issues addressed in the critique include provision exemptions, the ability to identify and contend with construction variability, and peculiarities of the equipment that affect the ability of VDOT to administer a modern acceptance provision.
