| dc.description.abstract | The title of the thesis presented herein, refers the primary objectives that underpin the
research work. As a high growing metropolitan city with high population density and
increased rate of transportation needs, the Roadway pavement of Dhaka city has to
sustain more traffic load than any other cities in Bangladesh. Moreover poor drainage
system in most of the city roads accelerates the deterioration of the pavements. For
these reasons, regular periodic maintenance has been adopted to keep the roads
functional. This study deals with the investigation and identification of road
construction faults and cracks before and after reconstruction and compare the results
to evaluate the effectiveness of the reconstruction. The pavements are visually
assessed and four assessment methods: DSCC, RHD, LGED Method and Texas
Innovation Group Method are used. Road construction are selected throughout the
Dhaka city to evaluate the effectiveness of reconstruction and increment of life span
of the pavements. Before reconstruction, most of the roads were in poor to fair to poor
condition. But later a periodic reconstruction after a specific interval, most of them
promoted into fair or good condition.
Finally, it can be said that, this assessment may prove itself useful for future planning
and implementation to ensure effective, comfortable, safe and efficient traffic
movement which may lead to a better transportation system throughout the city | en_US |
