An Approach to Identify the Impact of Human Intervention on Major Defects in Road Design, Construction and Maintenance

Abstract

The need to build and run roads offering structural integrity led to great advances in the fields of material sciences and fracture mechanics, but construction defects occur to either the new roads or the old ones. There are generally four categories of construction defects referring to roads: construction deficiencies, design deficiencies, material deficiencies, and subsurface deficiencies, but it is not uncommon for a design deficiency to link on to construction deficiencies in the structure.The paper aims to emphasise that people think different about hazard and safety especially when they build roads. Differently put, roads rely more heavily on their makers and users to limit both the occurrence and impact of human error in construction and maintenance on the one hand and to rectify and rehabilitate on the other hand to improve the safety performance of road transport systems and keep accidents from occurring.The paper aims to provide information about the defects occurred in the road construction and maintenance affecting human safety bringing forward practical examples. Moreover, it examines the materials widely implemented in the road construction from the viewpoint of their technological restraints and possible deficiencies. It also analyses some of the methods used on fields about how they might positively influence the road reliability and the human security implicitly.
