A Review of Road Pavement Failure: A Case Study of Nigerian Road.

Abstract:

The magnitude of failure/damages for several Nigerian roadways has prompted several scholars/analysts to look into the causes of these failures. In this paper, the underlying factors for roadway degradation on Nigerian highways are examined, along with potential solutions. An essential infrastructure in any settlement is recognised as the roadway. Solid pathways makes it easier to move people and things around, which boosts the economy. High accident rates, longer travel times, higher costs for vehicle maintenance, and high crime rates are just a few consequences of road failure that have been observed. Geology plays a significant role in the construction of roads because they are built on geologic earth materials and are significantly influenced by them. The main reasons why Nigerian roads fail are further identified in this paper as insufficient preliminary geological investigation, poor road design and construction, poor monitoring and quality workmanship, inadequate routine and regular maintenance, poor drainage, employing poor and low-quality materials, traffic congestion, overuse, incorrect use, and inadequate punishment for roadways failures. The majority of experts agree that Nigeria's road failure rate has recently grown despite the lack of concrete statistics. The solutions suggested include providing acceptable and adequate designs, oversight and quality control, clearing traffic on Nigerian roadways, prompt repair of such roads, constructing highway facilities, deploying skilled staff, and supportive government policies.
