EVALUATION OF RUBBER-ASPHALT MIXTURE USED AS A STRESS RELIEVING INNER LAYER

Critical shortages and spiraling costs of construction materials has necessitated investigation into new procedures which utilize readily available, recyclable materials which are normally wasted. One such method is the placement of ground tire-rubber mixed with asphalt cement as a stress relieving inner layer to be used on severly cracked and distressed pavements to prevent, or retard, reflective surface cracking in new pavement. This report deals with a demonstration study on SH 36 in Washington County which monitored the performance of the asphalt-rubber inner layer when in place and discusses the construction techniques used in its application. The rubber was mixed with asphalt in a distributor and applied as a seal coat directly on the existing pavement, except in a severely damaged areas which required prior patching. Two inches of asphalt stabilized base was placed on the rubber asphalt seal except in certain test sections where the rubber asphalt mixture was exposed to direct traffic. (Author)
