The pavement with lots of gaps aimed at improving the drainageability of the road surface reduces the noise generated by contact between tires and the road surface, and absorbs some of the sound generated by the engine, thereby reducing noise. It is said that the reduction effect is about 3 dB.

In Kanagawa Ward, it is used on Route 2 and other means.

In order to reduce the heat island phenomenon, Yokohama City has implemented pavements as "Suzu wind pavement" to control the rise in road surface temperature.

There are two types of suzu wind pavement: water-retaining pavement and heat-shielding pavement.

Water-retaining pavement

It is a pavement that suppresses the temperature rise inside the pavement due to the heat of vaporization when the water stored inside the pavement evaporates.

Heat shielding pavement

It is a pavement that suppresses the temperature rise of the pavement by reflecting a lot of infrared rays of solar radiation and reducing the amount of heat absorbed by the pavement.

By coloring (in some cases widening) the roadside zone of the road, pedestrian spaces are secured and attention is drawn to vehicle drivers.

This program is mainly implemented in collaboration with the School Zone Countermeasures Council, which consists of schools, Neighborhood Associations, police department and ward offices, for elementary school students whose road width is narrow and difficult to maintain sidewalks.

Asphalt pavement slabs and roadbed thickness (paving composition) of public roads in the city can be confirmed in the "Paving Type Map" in Public Works Office.

If you can carry out beautification activities on familiar roads as volunteer activities, there is a "Hama Road Supporter" system to support them.

We provide support so that everyone's activities, such as disposal of garbage and provision of cleaning tools, can be carried out smoothly. About system, please see page of City of Yokohama, Road and Highway Bureau administration section "Hama Road Supporter"
