Indirect tension test of hot mix asphalt as related to temperature changes and binder types

Hot Mix Asphalt (HMA) can deteriorate and crack due to the repeated loading from traffic and change in temperature. This study is to evaluate the effects of temperature and binder types to the strength of asphalt layer. Four types of hot mix asphalt were considered in this study which were AC 10, AC...

Civil engineering (General) Hot Mix Asphalt (HMA) can deteriorate and crack due to the repeated loading from traffic and change in temperature. This study is to evaluate the effects of temperature and binder types to the strength of asphalt layer. Four types of hot mix asphalt were considered in this study which were AC 10, AC 14, PMA 10 and PMA 14 and have been evaluated in the laboratory. For each type, the strength of the mixes have been compared related to different temperatures which are 25ºC and 40ºC using the Indirect Tension Test machine for resilient modulus according to ASTM D 4123 and the effect of binder types was also observed between bitumen type pen 80/100 and performance grade (PG) 76. Optimum bitumen content from Marshall Test results show that for AC10, AC14, PMA10 and PMA14 are 6.3%, 5.2%, 7.2% and 6.0% respectively. From the Indirect Tensile Modulus Test results it clearly shows that the values of resilient modulus decrease when the temperature is increase. AC10 and AC14 with bitumen 80/100 had higher resilient modulus at 25ºC compared to PMA10 and PMA14. However, at 40ºC the PMA10 and PMA14 shows vise versa. Bitumen pen 80/100 is suitable for low temperature condition because it has high resilient modulus value compared to PG76 but for high temperature, it is otherwise. From this study, PMA14 is found to be the best mix having the highest resilient modulus of all at 40ºC temperature, thus it is suggested that for Malaysia climate condition where the highest surface temperature is between 40ºC to 50ºC, PMA14 design is more suitable and will increase the pavement strength and lengthen the service time. 2010-11 Thesis http://eprints.utm.my/id/eprint/16473/ http://eprints.utm.my/id/eprint/16473/5/AkrimaAbuBakarMFKA2010.pdf application/pdf en public masters Universiti Teknologi Malaysia, Faculty of Civil engineering Faculty of Civil Engineering
