Experimental Investigation on Cold Mix for Road Construction Using Granite Aggregates and Rubber Waste

For many years, hot mix technique has been the main paving mix utilized in road construction. However, there are also drawbacks to the hot mix method, including the release of greenhouse gases, high energy consumption, and compromised bitumen durability as a result of ageing during heating. To overcome these disadvantages of hot mix technology, a cold mix technology is proposed by various researchers to protect the environment as well as for the conservation of energy. In this paper, a cold mix technology is adopted for the preparation of road construction materials using granite aggregate and rubber waste. The experimental results are obtained for pure granite aggregates, basalt aggregates, and a combination of both granite and basalt aggregates. The emulsion content determination test and Marshall Stability test were carried out to fix the optimum bitumen content. The usage of granite aggregates produces better outcomes than basalt aggregates, according to the testing findings.
