Abstract

Due to the high cost of crushed stone in Manaus, the construction of pavements is executed usually with asphalt sand mixtures and clay material in the base course, which has resulted in the appearance of different pathologies in the urban streets of the city. This study aims to identify alternatives for the pavements of the Manaus city by the use of industrial waste. A binder course with sand from construction residue (WCD) and asphalt cement (AC) modified by styrene and butadiene polymers (SBS) was used. Particularly, it was compared the mechanical behavior of the mixtures with the usual composite (residual sand and pure AC 50/70), through the Tensile Strength (TS) and the Resilience Module (RM). Additionally, in order to contribute to the solution of problems related to the sub layers, carbide lime (by-product from the manufacture of acetylene gas) was added to the clay soil and its performance was analyzed by Unconfined Compression Test (UCT). The results have shown that for the asphalt mixture, the inclusion of SBS polymer increases the TS, while WCD sand gave higher values both for TS and RM. Furthermore, the addition of carbide lime to soil decreases the plasticity index and enhances the UCT. Keywords: Industrial waste, WCD, carbide, SBS polymer, chemical stabilization.
