Flexible pavement design software software#

This flexible Pavement software can save the precious time and avoid the errors and difficulties occurring during the conventional methods of design. The results obtained from this software were analyzed and compared with the theoretical (manual) design and with the DARWin, a design software of AASHTO, and were found absolutely feasible and accurate.

This software can be used to determine the thickness of each layer, design life evaluation, knowing the relative damage factor, finding the various design variables like calculating the structural number and equivalent single axle load etc and climatic effects. The aim of this research is to develop software for the flexible pavement design based on the AASHTO, Group Index, and CBR. The design of thickness of the flexible pavement has taken the backbone place in determining the overall performance and providing high level of serviceability of the pavement structure for the heavy traffic loads under the adverse climatic conditions, during the expected design period.

And the analysis results turn out to be successful when it is compared with the manuals and books calculation.1 Software Development (PAKPAVE) for Flexible Pavement Design Rafi Ullah Khan, Muhammad Imran Khan and Afed Ullah Khan Abstract In today s world, the road and surface failure of the flexible pavement has become the most important and attention diverting problem, which may be due to the low quality of materials used, less and inadequate experience of the technical staff, and errors that may occur during the designing of the pavement. The result obtained by the developed software (AASHERA) is verified by comparing with the manuals and examples from different books. Besides, the designer or researcher can do as many alternatives as needed in short time. And the goals achieved are the thicknesses of surface, base and subbase layers of flexible pavement roads are determined and different design charts, default values and tables are digitalized.ДЇurthermore, comparison between AASHTO and ERA methods in terms of thickness and construction cost can be made to select the best design alternative. The development of the software is using MATLABR2008b programming language.

Manual design method has a drawback in avoiding human mistake, error and doing many alternatives for comparison as flexible pavement design involves different nomograph, charts, tables and formulas so it is cumbersome and time taking practice which may result in unsafe or uneconomical design. And it is known that pavement thickness design in our country is manual based. Finally, the thickness obtained using both design guides will be compared. The design in our country is based on the prevailing condition of soil and materials report using the Ethiopian Roads Authority ( ) Pavement Design Manual where the results obtained will be compared with that of the Structural Design Pavement manual.

Nowadays, flexible pavement roads and surface failure before the expected design period has become a critical issue in our country. This leads to the construction of road infrastructures which needs economical and safe design of roads. In Ethiopia the number and type of traffic increases and the change is alarming.
