Skid resistance and micro-structure of concrete containing waste plastic fiber for rigid pavement

This research analyzes the skid resistance and micro-structure of concrete by adding waste plastic fiber as an additive agent. There are parameters to be tested in laboratory scale such as ultrasonic pulse velocity (UPV) for chemical content related to concrete quality and skid resistance value (SRV) in the application of rigid pavement. The test is conducted by making concrete specimen in cylinder mold 150 mm ´ 300 mm. It is mandatory to test the concrete cylinders at the age of 28, then the concrete fragments from the compressive strength test are used for micro-structure testing through scanning electron microscopy (SEM) and UPV in order to check the quality of concrete and natural rocks. In this research, skid numbers from 5 mixing mode concrete pavements were collected using a British Pendulum Tester (BPT). The result shows that by adding waste plastic fiber additive into the concrete mixture in a huge amount (more than 1%) will decrease the concrete quality as it will have more concrete cavity. Based on the chemical test, there was no significant differences in terms of the percentage. However, based on the SRV test, high amount of plastic fiber will increase the level of skid resistance significantly. Based on this research, concrete with the waste plastic fiber as an additive agent can be used in the rigid pavement as it has higher SRV.
