Crumb tire rubber mixed asphalt concrete has a wide applicable area in road construction such as high energy absorbers and
thermal stabilizator. Rubber's high damping capacity allows consideration of rubber modified asphalt mixtures as part of a
damping system to decrease vibration therefore improving the comfort and durability of the pavement. Rubber particles may
also help from cooling off asphalt concrete during transportation from plant to the site. Heat loss of asphalt concrete during
transportation is one of the major problems in road construction. The slow rate of heat loss of the rubber mixed asphalt
concrete enables the mixtures to be produced even in cold weather conditions. Moreover, since rubber absorbs UV rays from
the sun, ice forming on the roadways could be reduced in the cold weather regions. To study the insulation effects of tire
rubber on asphalt concrete Marshall Stability tests were carried out in laboratory using different amounts and type of crumb
tire rubber on different temperatures. Applicability and effectiveness of final product were tested on site. From the results of
the tests in laboratory and site it is concluded that with the appropriate type and amount of rubber it is possible to reduce heat
loss of asphalt concrete. Insulation decreases the amount of energy required to replace heat losses, thereby reducing energy
costs. Rubber can also help reduce heat produced during production on site. This can provide cost effective and energy
efficient solutions and maintain environmental sustainability.
