It is known to researchers in the field of road construction and development. Three types pavement are rigid, flexible, composite paving. The consists a layer flexible on top which rigid placed or vice versa. All these have advantages addition disadvantages that affect performance one hand user convenience other. About 50 years ago, work began establishing type characterized by its semi-flexibl...

SYNOPSIS This paper presents the results of a study of pavement design based on the plate bearing list. The report supplements previous papers on pavement design, particularly the study reported in 1952 on the use of the triaxial test for design of flexible pavements. A series of tests was conducted on a test section of the Joint Highway Research Project Test Road. These tests were conducted by...

In recent years pavement maintenance planning has become a main task among highway agencies. In order to determine the structural capacity of a flexible pavement, non-destructive testing equipment is used. Many countries use the falling weight deflectometer (FWD). It is possible to obtain deflection data and backcalculate the pavements’ mechanical properties. However, the method used affects th...

The new AASHTO Mechanistic–Empirical Pavement Design Guide (MEPDG) provides pavement analysis and performance predictions for various feasible design scenarios. The MEPDG performance predictions for the anticipated climatic and traffic conditions depends on the values of the input parameters that characterize the pavement materials, layers, design features, and condition. This paper focuses on ...

The concept of rational pavement design for design of bituminous pavement was conceived during the 1960s (Dorman 1962, Monismith et al. 1961). Its upgraded version is known as Mechanistic-Empirical (M-E) pavement design, and is at present popularly being used for design of bituminous pavements in various countries. A number of pavement design guidelines (Austroads 2004, French 1997, IRC:37 2001...

Abstract Auto-regressive integrated moving average (ARIMA) assessment of traffic noise was conducted on different routes in Port Harcourt, Nigerian metropolis. This achieved by measuring the various asphalt flexible and concrete rigid pavement structures with a meter for sound measurement regards to volume traffic, vehicle movement rate, location away from midpoint highway. The peak obtained at...

Semi-flexible pavement surfacing, or grouted macadam, is an alternative to conventional flexible and rigid pavement. It constructed by injecting cementitious grout into the voids of open-graded asphalt surfacing. The cement used in grouts has adverse environmental effects because carbon dioxide emission production. objective this study was investigate potential using irradiated waste polyethyle...

Pavement crack is the main form of early diseases of pavement. The use of digital photography to record pavement images and subsequent crack detection and classification has undergone continuous improvements over the past decade. Digital image processing has been applied to detect the pavement crack for its advantages of large amount of information and auto detection. The application of digital...

This paper presents a fuzzy-based system that is used for maintenance planning of road pavements. The system has been developed based on knowledge elicitation from experienced maintenance engineers using fuzzy logic. The system includes functions for pavement condition and deterioration prediction, feasible treatment assessment in each pavement section, and maintenance planning in a road networ...
