The Research on the Temperature Resistance Test of Polypropylene Geotextile in Asphalt Overlay

Abstract:

The melting point of polypropylene geotextile is 170 centigrade. However, during the repaving design of the old cement concrete pavement, the paving temperature of the asphalt mixture is often 160-170 centigrade or above. Therefore, it is very important to verify that whether the polypropylene geotextile can be paved under a high temperature. Through the modeling and analysis of temperature fields and relevant temperature tests in the laboratory, the paper has tested the surface temperatures of the polypropylene geotexile when the asphalt mixture is paved under a high temperature. The results show that, under a simulated paving temperature of over 190 centigrade, the highest temperature of polypropylene geotextile is only about 160 centigrade, which is lower than its melting point. Therefore, the polypropylene geotextile can be used for the paving under a high temperature.
