Trr No. 1384 Strength And Deformation Characteristics Of Pavement Structures
Performance of sections of the Nairobi to Mombasa road in Kenya
Nine sections of road with sement-stabilised bases surfaced with multiple seals, and three sections with crushed rock bases and asphaltic concrete surfacings have been studied for seven years. These road sections are located in a dry area, on strong subgrade soils. It was found that the lightly constructed sections with cement-stabilised bases had suffered little structural damage after carryin…
Performance of unsealed roads in Ghana
This report gives results of measurements of the condition of unsealed roads made over a period of more than two years. The effects of the maintenance activities of grading and dragging on road surface conditions are assessed. During the study some of the running surfaces deteriorated sufficiently to significantly increase road user costs. Roughness was the aspect of running surface condition w…
Monitoring tingkat kinerja jalan arteri primer
Perlunya kajian untuk mengidentifikasi persoalan tingkat kinerja jalan terukur (kuantitatif) dari kondisi eksisting jalan, merupakan sumber penting sebagai tolok ukur informasi mengenai masalah lokasi yang paling serius dan menetapkannya sebagai urutan prioritas pengembangan dan rekomendasi untuk keperluan evaluasi, diagnosis, pengambilan keputusan dan pemberi peringatan. Analisa tingkat kinerj…
Pavement Distress Surveys in the Strategic Highway Research Program's Long -T…
The Pavement distress data collection of the Long-Term Pavement Performance (LTPP) study is a part of the Strategic Highway Research Program. Pavement Distress data are important component of the international data base that will be developed during the LTPP. The Pavement distress information is to be collected on 500-ft (!52-m) monitoring sections on a periodic basis ti provide a historical da…
SHRP Long-Term Pavement Performance Information Management System.
TRR No. 1260 Pavement Design, Management And Performance, pp. 33-41. The Long-Term Pavement Performance (LTPP) project is a major component of the Strategic Highway Research Program (SHRP). This 20-year effort is the most intensive evaluation of pavement performance since the AASHO road Test in the early 1960s. Over 700 in-service general pavement sections throughout the United States and Cana…
Criteria for Evaluating Pavement Imaging Systems.
TRR No. 1260 Pavement Design, Management and Performance, pp.64-73 A number of pavement imaging systems have been developed in the last few years. Choosing the system that will best fit an agency's needs and resources is a difficult task, because of the wide variation of alternatives. However, automated pavement imaging systems technology is mature enough to be broken down into a distinct set …
A State's Concerns with the FHWA's Highway Performance Monitoring System Roug…
Trr No. 1311 Pavement Design, Management And Performance: When the FHWA issued requirements for the collection of roughness data for the Highway Performance Monitoring System in December 1987, it was well received in Texas. The benefits of a national pavement roughness standard and the concerns that evolved from a study conducted by the Center for Tranportation Research at the University of …
Effect of Design Parameters on Performance of Road Profilographs
Trr No. 1311 Pavement Design, Management And Performance, pp. 9-14 Road profilographs are commonly used to measure roughness of new and newly surfaced pavements. Because new pavements are usually smooth, profilographs must have measuring sensitivity, particularly in the range of profile wavelengths responsible for dynamic pavement loading applied by heavy trucks and for ride comfort. Simple an…
