“…Among all polyolefin, the scientific community has directed particular attention toward polyethylene (PE) and polypropylene (PP). 13,15,[17][18][19][20][22][23][24][25]27,28,[32][33][34][36][37][38][39][40][41][42][43][44][45][46][47][48][49] These two thermoplastic semicrystalline polyolefins represent the globally most produced plastic materials employed for the massive production of tools of any sort. Given the relatively low melting temperatures (<170 C) and high thermal stability, these materials well fit in the production protocols of MBs from a practical point of view.…”

“…On one side, in fact, the literature shows that PEMBs and PPMBs are still often evaluated through empirical methodologies. 19,22,25,32,[44][45][46][47][48][49] Those methods (e.g., penetration test, softening point test) categorize effectively unmodified binders but have been proved to be inadequate for evaluating the performance of more complex bituminous compounds. On the other side, it appears that the manufacturing protocols generally adopted for PEMBs and PPMBs in a laboratory setting emulates the standardized protocols used for traditional PMBs.…”

“…Recyclable and waste materials do not only lead to a consistent reduction of the modified bitumen (MB) overall costs, but provide benefits at an environmental level too, and their application has been largely incentivized 1,9,12–30 . For these reasons, waste plastics are nowadays considered some of the most interesting replacements of traditional polymers and extensively investigated worldwide 9,12,13,15,17–48 . However, unless other waste materials, plastics are often mixtures of unknown composition, and a better understanding of the effects of each type of polyolefin is needed.…”

Variation of internal structure and performance of polyethylene‐ and polypropylene‐modified bitumen during blending process

Linear-viscoelastic characteristics and performance are evaluated throughout the blending process of polyethylene and polypropylene with bitumen. Results indicate that type, form and percentage of polyolefin play a significant role in the time evolution of the composite's mechanical response. Toluene extraction of modified bitumen revealed, for the first time, the formation of a sponge-like polymer network. Visual inspection and Fourier transform infrared analysis of the polyolefins recovered after extraction indicates higher affinity of the polyethylene with bitumen in agreement with the rheological test results. The use of polypropylene is discouraged if rutting performance is a concern, and polyethylene in both pellets and powder form at 4%, and after 210 min of blending produces a modified bitumen with acceptable performance.

“…In Nigeria and many other countries, the safe disposal of solid waste is of great concern to their environmental protection agencies. The random disposal of worn-out automobile tyres and plastics is considered to be one of the major causes of damage to our ecosystem that result in alarming health problems for all types of life (Sulyman et al, 2014). Also, plastics have been habitually mixed with our municipal solid wastes and sometimes disposed of in soil; in terms of their chemical characteristics as represented by their chemical bonds, they are very durable and non-biodegradable; they therefore require very effective management worldwide (Sulyman et al, 2014).…”

The Use of Polyethylene Terephthalate Waste for Modifying Asphalt Concrete Using the Marshall Test

This study considers the use of polyethylene terephthalate (PET) waste for modifying asphalt concrete. In the study, the optimum bitumen content of asphalt concrete was replaced with 4%, 6%, 8%, 10%, 12%, 14% and 16% of PET waste; the Marshall test was conducted on the samples. A comparison of the unmodified and PET-modified asphalt concrete showed that the stability of the modified asphalt concrete was reduced. The maximum stability for the PET waste-modified asphalt concrete was recorded at a content of 12% PET waste. This gives about a 20.4% reduction in stability. The study reveals that the addition of PET waste to the asphalt concrete causes a reduction in the flow value except with the addition of 14% and 16 % waste. This implies that the introduction of PET waste could improve the permanent deformation resistance of asphalt, although there is concern about a reduction in fatigue resistance.

“…Asphalt is a pavement material that is brittle and hard in cold environments and soft at elevated temperatures. It has been historically employed as the most popular paving material for roadways [1]. Traditionally, Hot Mix Asphalt (HMA) has been widely used for road construction.…”

Effects of Reduction in Construction Temperature on Workability of Warm Mix Asphalt Incorporating Rh-wma Additive

Conventional Hot Mix Asphalt (HMA) has been the primary material used in pavement in past decades. Recently, compared to conventional HMA, Warm Mix Asphalt (WMA) has shown great potential and offers benefits not given by HMA, since the WMA can be produced at lower temperatures without affecting pavement performance. The WMA technologies allow a significant reduction in construction temperatures of asphalt mixtures through lowering the viscosity of binders. In WMA, different types of additives are added to the binder depending on the technology used and such addition of these materials brings down the viscosity drastically thus reducing the temperature to which the aggregates and binders have to be heated during mixing and compaction. This study was limited to the effects of construction temperature on the workability performance of WMA incorporating RH-WMA additive. Binder namely 80/100 was used for preparation of all asphalt mixtures and RH-WMA used as warm mix asphalt additive. Asphalt mixtures were prepared using crushed granite aggregate for AC14 wearing course and compacted by using Servopac Gyratory Compactor (SGC). The Leeds Workability Method used to determine the workability index. The results show that increase in construction temperature improves the workability of both WMA and HMA. Workability Index (WI) of mixtures incorporating 3% RH-WMA is slightly higher than mixtures incorporating 2% RH-WMA. The increase in WI is more pronounced at higher RH-WMA contents.
