Abstract
This research aims at investigating roughness in asphalt mix, and to address its effects, causes and methods for treating it to provide safe and smooth driving for the drivers and to the roads users in order to reduce accidents, loss of properties and consumption of fuel which reflects on saving financial costs. The research has depended on qualitative research method through reviewing a number of previous studies related to road constructions, since the desired high quality of roads has become priority to the road users and to the environmentalists who seek to reduce air pollution and emission of harmful gases.
Highlights
Expansion in the housing sectors, building new complexes, and the increasing number of people who own vehicles and using them for transportation, and for economic purposes in exports and import of different products and services which require the use of heavy trucks this rapid increase in the movement and use of the roads have led to the increase demand & interest in quality of the roads regarding its pavement mix to attain the optimal usage, reduce fuel consumption, and safety at the roads, users
Road maintenance plays important role in reducing roughness of pavement surface, since understanding the impact of roughness coupled with the pavement deterioration rate and road design can help stakeholders understand ways to improve road design and maintenance schemes in order to minimize fuel use and consumption and greenhouse gas emission to maximize the use of limited road construction and maintenance funding (Greene, S et al, 2013)
Roughness of road pavement surface is seen as increasing the amount of resistance a vehicle experience as it travels down the road, requiring additional amount of fuel to maintain a certain speed
Summary
Expansion in the housing sectors, building new complexes, and the increasing number of people who own vehicles and using them for transportation, and for economic purposes in exports and import of different products and services which require the use of heavy trucks this rapid increase in the movement and use of the roads have led to the increase demand & interest in quality of the roads regarding its pavement mix to attain the optimal usage, reduce fuel consumption, and safety at the roads, users. People use different means for transportation like cars, busses and trucks for different activities, whether commercial or industrial activities. Such an increasing activities require cement pavement mix which guarantee safe and cost-effective travel and usage of the roads. A good and in-depth understanding of these factors would enable pavement specialists to construct smooth, cost-effective, and long-lasting pavement to satisfy the needs expectations of the road users (Eibheiry, Kandil & Kotop, 2011).
