Double Layer Concrete Paving Blocks Using Waste Tyre Rubber as Aggregate Replacement

Abstract

This study provided the test results on the mechanical properties of double layer concrete paving blocks (CPBs) obtained by replacing portions of the conventional aggregate with waste tyre rubber. The mechanical properties discussed in this paper were compressive and flexural strength. Results indicated that the density of double layer CPBs containing rubber was lower than that of conventional CPB. The decrease was found to be proportional with the waste tyre rubber content. Due to the low strength and stiffness of waste tyre rubber particle, the compressive and flexural strength of double layer CPBs containing rubber appeared to be lower than that of conventional CPB.

Automotive Wastes

“…The addition of rubber ash and rubber ash plus rubber fibers also had an effect on the abrasion resistance, carbonation depth, modulus of elasticity and chloride penetration of the modified concrete as compared to plain concrete (Gupta, Chaudhary, and Sharma, 2014). Jusli, Nor, Ramadhansyah, and Zaiton (2014) and Jusli, Nor, Jaya, Haron, and Azman (2014) investigated the use of waste tire rubber as an aggregate in the production of concrete paving blocks. When waste tire rubber was added at levels of 10, 20, 30 or 40%, concrete with 10% rubber was able to achieve the minimum strength requirement of 45 MPa.…”

“…Waste Tires. Waste tires have been investigated for use as a raw material in the production of composite materials (Ahmetli et al, 2014;Hamim et al, 2014;Pang and Ismail, 2014a, 2014b, as an additive to concrete (Barbuta et al, 2014;Herrera-Sosa et al, 2014), as an aggregate in concretes (Flores-Medina et al, 2014;Gesoǧlu et al, 2014;Gupta, Chaudhary, and Sharma, 2014;Jusli, Nor, Ramadhansyah, and Zaiton, 2014;Jusli, Nor, Jaya, Haron, and Azman, 2014;Meddah et al, 2014;Serdar et al, 2014), as a Water Environment Research, Volume 87, Number 10-Copyright © 2015 Water Environment Federation modifier in bituminous composites (asphalt pavement) (Karakurt, 2014;Mashaan and Karim, 2014) or as a filler for thermoplastics (Lu et al, 2014). Barbuta et al (2014) suggest that the small loss in mechanical properties (2 to 16%) is balanced by the relatively high use (30%) of waste tires, since the cost of the concrete does not increase significantly.…”

Stiffness modulus and creep properties of the coconut shell in an asphalt mixture

“…These materials should be used wisely to attain sustainable development. A large number of studies have been conducted to search for a possible material as an aggregate replacement in road conductions [4][5]. Currently, using agricultural waste materials as an aggregate replacement becomes a trend in the construction industry [6][7].…”

Sound absorption and morphology characteristic of porous concrete paving blocks

“…Porous surface has been introduced to reduce the tyre noise. A dense road surface reflects the sound energy, while a porous road surface absorbs the sound energy [5][6][7]. Ferguson also states that a porous surface absorb sound energy and allow some of the air around the tires to be pressed into the voids, wipe out air pressure before any noise is generated.…”
