Abstract

The study was conducted to study the effects of the use of pieces of rubber as a partial substitute in bitumen flexible pave ACW 14. Bitumen is one of the binder materials used in construction of roads and pave has increased prices and costs to achieve it. As a result of increasing economic and traffic load, road bitumen structure designed should have the durability and capability services play a key role in the communication network, the most important. Objective of this study is to reduce the quantity of bitumen used and replaced with pieces of rubber. Therefore, many efforts have been undertaken to improve the quality of the existing bitumen. In this study, modified bitumen grade 80/100 pricking is done with the addition of various pieces of rubber per cent content. Percentage of rubber used is 0%, 3%, 6%, 9%, 12% and 15% of the total amount of bitumen used. ACW 14 mixes compacted with mechanical junkie and tested values Marshall Stability. Potential ACW 14 modified with a mixture of rubber elasticity modulus obtained by studying, scorching and Maximum Load and then compared with the control capabilities through a mixture of ACW 14 Indirect Tensile Test. Once the three parameters were studied, the percentage of rubber content can be determined that the optimal content of 12% rubber. Based on studies conducted, it found pieces of rubber bitumen ability to increase capacity by an increasing in the occurrence of Blowing Point Temperature Index and pricking of altered samples. It also can decrease the value of pricking. In addition the ability of a mixture of slip resistance also showed good results through the slip resistance test. Overall analysis carried out shows, the addition of pieces of rubber in the mixture can enhance the capability of the mixture 14 as ACW pave flexible.
