| Abstract | ||||
| In addition to its positive impact on the growth and prosperity of the national economy and its importance for satisfying our individual needs for mobility, road transport also has adverse effects: accidents, noise, air pollution, harm to health, crop damage, jams, etc. The outside factors that have adverse &act on the pavement are environmeht, trafiic and pavement maintenance techniques. Pavement maintenance is carried out to reduce the rate of pavement deterioration and subsequently the negative impact of traffic environmental pollution. An effective pavement maintenance program will address pavements, while they are still in good condition and before the onset of serious damage. By applying a cost-effective treatment at the right time, the pavement is restored almost to its original condifion. The cumulative effect of systematic, successive maintenance treatments is to postpone costly rehabilitation and reconstruction. Deferring of pavement maintenance leads to more deterioration of pavement, reduction of operating speed and then more pollution to air. The impact on health, welfare and the natural environment are considerable sensitive and having an intangible costs caused by 'them; These costs are mainly external not covered by the polluters (the motorists) but imposed on everybody. External costs cause. a problem to the economy, as they are not included in the market price, which leads to wrong decisions and to a wasting of scarce 8nd vital resources (cleh air, silence, clean water, etc.). Motorists behave as if those costs do not exist, since they do not have to pay for them. The objective of this paper is to quantify the influence of pavement condition status on the environment issue represented by Carbon Monoxide (CO) emission values. To achieve this, the paperconsists of four main parts. The first part includes an overview of pavement condition evaluation and the intended performance prediction models. In the second part, a description of the relation between pavement condition and traffic speed will be discussed with the required correlating models..The.third part includes quantification of air pollution results from traffic speed reduction within anticipated models. Finally, the offect of pavement condition on traffic environment pollution was identified witbin an analysis to practical data of different road sections. The results. indicate th~t pe enviyovt willbe affected by 0.276,0.176, 0.314,0.333, 0.279 and 0.513 ton of CO daily and accumulated iife cycle emissions values; 744.57, 466.58, 799.66, 688.88, 841.17 and 97?.14 ton for .the studied sections respectively depending on variables of pavement cogditiqn and traffic volume. The pavement condition has a major impact on the environment than the ,traffic volume as defmed hereinafter. There is a direct proportional of payem@ condition with traffic speed and subsequently an inverse relation with the environment emission values, which will affect to the economy and welfare of people. | ||||
