“…Temperature variations within the pavement structure contribute in many different ways to the possible failure of that structure. Under loading conditions, the road surface temperature is a major factor affecting the deformation of bituminous structures (Al-Abdual Wahhab et al, 2001). A harsh environment with a high traffic load operating on the road network makes the road surface more susceptible to a wide range of types of distress.…”

Assessment of road surface condition is a crucial part of pavement management systems (PMS). A comprehensive assessment of the road surface condition in a metropolitan area will result in the efficient allocation of resources and a successful road surface maintenance plan. This process is usually undertaken either through manual inspection, which is highly demanding in terms of manpower, or it is outsourced to specialised companies that use highly sophisticated and expensive equipment. Usually large cities and municipalities can afford to outsource this task.However, small cities and municipalities cannot afford either the automated or the manual method due to their limited resources. The objective of this paper is to make a reasonable compromise between cost and accuracy by developing an economical system for making an initial assessment of the condition of road surfaces. The initial assessment will be automated to cover the jurisdiction of the municipality. Following the results of the initial assessment, decision-makers will then be able to identify the areas that will need further manual assessment. The results of the system will be tested and validated using manual inspection. The final product of the proposed integrated PMS will be a working prototype that can be mounted on a passenger car or light truck.

The mechanical performance of asphalt pavements is closely related to temperature. On the basis of the Laplace transform, this article presents a method to determine dynamic temperature profiles of pavements under site conditions such as location, air temperature, cloud cover, time of day, day of year, material parameters. The main advantages of the present method are no time steps are needed, and unconditional numerical stability, and rapid convergence. By using the present method, we can separate temperature profile analysis with the followed stress and deformation analysis, which will benefit pavement design.

“…Only few studies have been conducted in the countries within the Arabian Peninsula to evaluate the benefits of using mechanistic-empirical design and construction of perpetual pavements (Al-Abdul Wahhab and Balghunaim 1994, Al-Abdul Wahhab et al 2001, Masad et al 2011. Most of these studies focused on characterisation of local materials, influence of increase in traffic loading on performance and rutting due to high temperature.…”

The State of Qatar is experiencing tremendous growth in infrastructure including road network and highways. The current methods used in design of asphalt pavements in the State of Qatar are empirical and might not be suitable for the design of long-lasting pavements. Given the significant increase in traffic, road authorities in the State of Qatar have been considering the use of mechanistic-empirical methods in the design and analysis of asphalt pavements. This study documents the results of a study in which the mechanistic-empirical pavement design guide (M-E PDG) software was used in the design of asphalt pavements with input parameters that were carefully selected to reresent local materials and climatic conditions. The selection of material properties was based primarily on specifications and design guides in the State of Qatar and on published literature about these materials. The mechanistic-empirical method was also used to assess the benefits of adopting the concepts of perpetual pavement design and also to compare the performance of pavement structures in which various bitumen grades, granular bases and chemically stabilised sub-base were used. A life-cycle cost analysis was carried out to determine the design with the highest net present value among the various options investigated. It is expected that the outcomes of this study would promote the use of mechanistic-empirical methods in the State of Qatar and the region. Inevitably, this will require significant efforts to calibrate material and damage prediction models used in the M-E PDG for more accurate representation of material properties and measured pavements performance.
