“…Much attention has been paid to this, and several publications deal with this problem [12,13], in particular, considering that r-PET for food packaging may derive from PET not used for food [3,14]. Moreover, the physical properties of r-PET have been studied [15][16][17], and several possible advanced applications, other than food packaging, have been evaluated [18][19][20].…”

A novel approach for the quantification of recycled polyethylene terephthalate (r-PET) in commercial bottles is presented. Fifty-eight bottle samples from several brands and producers containing different percentages of r-PET were purchased from the market. Samples were analyzed by two spectroscopic methods: near-infrared (NIR) spectroscopy and attenuated total reflection (ATR) spectroscopy in the mid-infrared (MIR) region. No chemical pre-treatment was applied before analyses. The spectra were analyzed by partial-least squares (PLS) regression, and two models for NIR and MIR data were computed. Then, a multi-block regression was applied to join the two datasets. All models were validated by cross-validation and by excluding and projecting onto the model the replicated spectra of one sample at a time. Results demonstrated the potential of this approach, especially considering the variability of commercial samples in terms of additives, shape, or thickness of the bottles: for samples close to the centroids of the models (i.e., from 10 to 50% r-PET), the predictions of multi-block method seldom departed from the expected values of ±10%. Only for samples with 0% declared r-PET, the models showed poor prediction abilities.

Dalam beberapa kasus dilakukan berbagai upaya dilakuakn dalam meningkatkan serta memperbaiki kualitas konstruksi jalan dengan melakukan peningkatan stabilitas, perbaikan tanah, hingga penggunaan geosintetik [9] [10]. Dengan perbaikan tanah, daya dukung meningkat, penurunan akan berkurang, serta kinerja permukaan meningkat.…”

Roads as a means of transportation have an essential role in supporting human activities. One of the developments in road construction is the application of geotextiles in road combination pavements. Geotextile itself is often found in construction planning, especially in soil stabilization. The plandaan – boro Tulungagung road section is indicated by the type of silt as deep as 1.2 meters so that improvements are needed to support the quality of road construction. The purpose of this research is to plan road pavement with geotextiles on the Plandaan to boro roads. The geotextile used is a woven geogrid geotextile. The method used in planning is the Bina marga method of the 2017 Road Pavement Design Manual. The data used include technical data, traffic data, and California Bearing Ratio (CBR). The planning includes traffic design, pavement thickness calculations, and volume calculations. The planning results will be HMA – WC pavement covering an area of 4,200 m, with K225 concrete pavement covering an area of 8,400 m. Class Bﬞ Aggregate Pavement covering an area of 10,500 m using a geotextile layer requires 51,000 m² so that these results can be used as a reference in the repair or improvement of the Plandaan - boro Tulungagung road.

Mathematical modeling of improving the characteristics of bitumen for asphalt concrete by modifying

A significant increase in traffic intensity and increased axle loads of vehicles on the roads led to the fact that asphalt concrete is not able to provide the required durability of road surfaces. The durability of asphalt concrete pavements is directly related to the quality of the materials used, primarily bitumen. Bitumen is most susceptible to changes under the influence of traffic loads and weather conditions. At the same time, bitumen largely determines the condition of the road surface. The behavior of bitumen can be changed by modifying it with additives. The novelty of bitumen modification lies in the fact that the addition of polymer to bitumen makes it possible to obtain a road surface that is resistant to cracking at low temperatures and to provide fatigue strength at high temperatures. Rutting resistance is also achieved. An important role in the choice of the modifier is played by economic issues related to the rise in the cost of coating, as well as the need to use additional equipment, the stability of the modified binder during storage and transportation, etc. Carbon nanotubes (CNTs) were used as a modifier for asphalt concrete mixtures. During the experiment, a significant improvement in the main indicators of asphalt concrete mixtures was revealed, as well as the maximum permissible deviations for the amount of binder in the asphalt concrete mixture and for the main indicators were observed. Moreover, the most important thing that has been achieved is a significant increase in rutting resistance by rolling a loaded wheel.
