Experimental Study of the Evolution of Temperatures in Pavement Structures and Influence of Traffic on the RN1 in Burkina Faso in a Hot and Dry Climate

Asphalt concrete pavements in hot and dry climates deteriorate prematurely some time after their construction. This degradation is accelerated under the effect of heavy vehicle traffic pressure high temperatures bitumen has softened. A study was conducted on RN1 Burkina Faso order to analyze evolution temperature process asphalt pavements. It consisted one hand recording at different points inside layers layer laterite. These results were compared with values softening obtained laboratory. On other hand, this supplemented by daily counting goods vehicles passing through during month April influence climatic conditions. The for frequency favor pavement deterioration certain
