WELL-MAINTAINED ROADS REDUCE TRAFFIC CO_2

摘要

The road pavement directly influences vehicle fuel consumption through the rolling losses experienced by a vehicle riding over it. Rolling losses include both energy losses in the suspension system due to an uneven road, and losses at the level of contact between the tyre and the pavement. Various aspects of the quality of the road surface influence rolling losses: evenness, ruttirfg, potholes and deteriorated joints. Other factors, such as pavement characteristics, can also influence rolling losses. Poor quality or deteriorated pavements contribute to higher rolling losses. Road maintenance will reduce emissions immediately and for the future. Road maintenance can contribute to CO_2 reduction in two ways: 1. Road maintenance or upgrading improves the smoothness of the road. This will lead to a reduction in vehicle CO_2 emissions. 2.By applying new surface layers with low rolling resistance in mind, an even greater CO_2 reduction will be achieved. In both cases, other aspects such as a higher durability can be built in to ensure that the reduction continues into the future.
