“…The Marshall testing procedure employed was consistent with those conducted by other researchers 3,34 and involved following the standards outlined by ASTM D6926-10 (Standard Practice for Preparation of Bituminous Specimens Using Marshall Apparatus Practice for Preparation of Bituminous Specimens) 35 and ASTM D6927-15 (Standard Test Method for Marshall stability and Flow of Asphalt Mixtures). 36 Samples were analysed in triplicate and were subjected to compression at a rate of 50.8 mm/min until either a reduction in load was recorded or until the dial gauge released.…”

This research investigates the influence of waste polymeric polyethylene terephthalate (PET) materials obtained from waste plastic bottles and crumb rubber (CR) obtained from used automobile tyres on the performance (Marshall stability, flow and compression) and durability (weathering) characteristics of road-paving material made from Trinidad Petroleum Bitumen and the world-renowned Trinidad Lake Asphalt. Apart from possibly serving as additives to improve performance, incorporating waste PET and CR in asphaltic road-paving materials also offers a viable means of alleviating health and environmental problems associated with the waste disposal of PET and CR. The results of the Marshall testing found that the optimum dosage for polymer modification was 1.0% and 5.0% for PET and CR polymers, respectively. In comparison with a Marshall stability value for the unmodified asphalt sample of 10.2 kN with a corresponding flow value of 3.1 mm, the 5% PET modified sample had a Marshall stability value of 10.2 kN with a flow value of 3.2 mm, while the CR modified sample recorded the highest Marshall stability value of 10.7 kN at corresponding flow value of 2.8 mm. An undesirable trend of the gradual increasing of the voids in mineral aggregate (VMA) with incremental increases in the % of added PET and CR was observed; however, for all the modified specimens with the exception of the 5% PET modified sample, the VMA fell within the acceptable range of between 14% and 20%. The results of accelerated weathering and compression testing demonstrated that both the 1% PET and the 5% CR-modified samples had higher durability and compressive strength characteristics than the unmodified samples. Compressive stress values for the polymer-modified specimens were in excess of 45% compared to the unmodified ones. The relevance of the values obtained in this study cannot be ignored as it provides practical and essential data, especially of the optimal dosages of PET and CR required for the enhancement of the mechanical and durability properties of the Trinidad road-paving materials while simultaneously providing an environmentally desirable and sustainable method for reusing these waste polymers. Commercial application of the optimum formulation can be immediately implemented.

“…Marshall tesing was conducted as outlined by previous studies [31]. The procedures employed to execute the Marshall tests were done according to the standards outlined by ASTM D6926 – 10 (Standard Practice for Preparation of Bituminous Specimens using Marshall Apparatus Practice for Preparation of Bituminous Specimens) and ASTM D6927 – 15 (Standard Test Method for Marshall Stability and flow of asphalt mixtures) [32,33].…”

The reuse of waste crumb rubber (CR) (used tyres) and Polyethylene Terephthalate (PET) (plastic beverage bottles) is of particular interest in Trinidad and Tobago since present disposal techniques presents environmental and health challenges. The results of this study investigating the influence of PET and CR on the performance characteristics of the HMA2 pavement design using Trinidad Lake Asphalt (TLA) and Trinidad Petroleum Bitumen (TPB) filled an information gap as no previous studies utilizing these indigenous asphaltic materials exist. Existing information using asphaltic materials other than TLA and TPB are irrelevant as variations in performance characteristics due to the addition of polymeric additives can vary from asphalt to asphalt due to differences in source and chemical composition of the parent binder. The results of this study show that a 6% CR and PET addition achieved the highest performance advantage demonstrated by an increase in the Marshall Quotient of between 21–22% and an insignificant decrease in the Bulk Specific Gravity (0.2%) compared to the unmodified blend. The improvement in the mechanical properties and the performance of the modified pavement materials observed is evidence of the useful effects of these waste materials in road paving design and offer a beneficial strategy for the reuse of these waste materials.

“…A curve of the compressive load (kN) versus crosshead displacement (mm) was used to estimate the peak load. The compressive strength was then estimated using equation ( 5): (5) where F is the peak load at the onset of fracture and is the initial cross-sectional area. Experiments were repeated (n = 5) and average values were reported.…”

This paper presents a recent study on recycling poly-ethylene-tetraphylate (PET), known as plastic waste material in Ghana, to wealth. Composites were produced by heating aggregates together with shredded PET plastic waste material, while bitumen was added to the plastic-coated aggregates. The composites produced were reinforced with 4.5 wt%, 9.0 wt%, 13.6 wt%, and 18.0 wt% PET. Mechanical properties of the fabricated composite samples were studied with a Universal testing machine for optimization. The work demonstrated that shredded PET plastic waste material acts as a strong binding agent for bitumen that can improve on the shelf life of the asphalt. From the results, 13.6 wt% concentration of PET was shown to experience the maximum compressive strength and flexural strength. Besides, water resistance was shown to increase with PET concentrations/weight fraction. From the data characterized 13.6 wt% of PET plastic gives the optimum plastic concentration that enhances the rheological properties of bitumen. The implications of the result are therefore discussed for the use of 13.6 wt% PET in road construction.
