ROAD SIDE PLANTATION MAY HELP TO PROLONG THE LIFE OF THE SURFACE,AS AFFECTING THE TEMPERATURE

The road side plantation is very useful to protect the environmental atmosphere of the area and circle as providing the shaddy coverage during the hottest part of the day and helping to reduce the temperature. The chief influence exerted by the influence of trees upon the road surface is a reduction in daily raising temperature of the road surface during peak hours, and definitely prevents licking up of the tar coal the formation of the pot holes and ruts and prolong the life of the road surface. Rays of the sun have a deleterious effect both upon tar and the bitumen ,as such the presence of the road side trees reduce this effect. The value of shaddy coverage therefore helping the envoirnmental protection of the tarred surface during the hot weather and keeping the road in good condition. For earth and the Water bound Macadam roads trees have a great effect in that by reducing the surface temperature they minimise the loss of moisture content in the soil in the hot weather as trees have the advantage of holding the dust created by the motor vehicle traffic , however the trees must not interfere with the traffic on the road and should have stemps free from the branches for a height of 2.4 to 3 metres and the pruning of the trees must be done in such a way that the natural shape of the foliage is retained as for as possible.
