“…In the road-building process, rubber and oily sludge can be used as an asphalt binder mixture. Since this mixture can withstand low temperatures of −28 °C, so the asphalt surface layer does not crack [41]. Another advantage of this material is reducing energy consumption to obtain asphalt mix for road paving [42].…”

The price and consumption of rubber experienced a decline due to the global economic crisis, the US-China trade war, and coronavirus. This situation is unprofitable for Indonesia, and it must develop new target markets. Central Europe is one of the potential markets for Indonesian rubber. This study aims to ascertain the performance of the Indonesian rubber exports to Central European countries and forecast its future. The research used Indonesian rubber export data to Hungary, Poland, and Romania from January 1999 to March 2021. Descriptive statistics and autoregressive integrated moving averages were used to analyze the data. In the last three decades, Indonesian rubber exports to Central Europe have risen. The short-term forecasting indicates that Indonesian rubber exports to Poland will increase; on the other hand, exports to Romania will experience a decline. Meanwhile, exports to Hungary were relatively stable. This result was obtained using ARIMA estimation with different models for each country, respectively ARIMA(1,0,5) in Poland, ARIMA(2,0,1) in Romania, and ARIMA(2,0,1) in Hungary.

“…Highly modified asphalts have above-standard characteristics, such as: very good resistance to rutting [3], resistance to water and frost, resistance to cracking under low temperatures [4], high fatigue strength [5,6,7]. These asphalts are dedicated in particular for surfaces characterized by increased traffic loads, substructures of high fatigue strength and asphalt layers characterized by high resistance to low temperatures.…”

The article presents results of research on the possibility of reduction of technological temperatures of highly modified binders by using as an additive a fluxing agent of plant origin, developed at the Warsaw University of Technology. The work presents the results of dynamic viscosity tests within the temperature range of 90°C to 180°C for original binders and binders aged using the RTFOT method, modified by adding a fluxing agent of plant origin. On the basis of dynamic viscosity test results, process temperatures for production and compaction of mineral-asphalt mixes with the binding agents being analyzed. Moreover, characteristics of binders were assessed, which define their behavior under high technological temperatures on the basis of multiple stress creep recovery (MSCR) tests.The research results obtained indicate that it is possible to reduce the process temperatures of mineral-asphalt mixes with highly modified binders by liquefying the binder with an additive of plant origin while retaining high resistance to permanent deformations. The MSCR test results prove that mineral-asphalt mixes containing binders highly modified with additives of plant origin can meet the requirements for extremely high traffic loads.

“…Similar problems of inconsistency between the brittleness temperature of the produced bitumen and winter climatic temperatures exist in different countries of the world. For example, in recent years due to the deterioration of the climate, in some regions of Eastern Europe, extreme low temperatures up to −40° C have been recorded [4].…”

A comparative assessment of the effect of two modifiers on the low-temperature properties of BND 90/130 bitumen was investigated using Asphalt Binder Cracking Device (ABCD test) and Dynamic Shear Rheometer (DSR 4-mm test). These modifiers are styrene-butadiene-styrene block copolymer (SBS) and active powder of discretely devulcanized rubber (APDDR) - powder elastomeric modifier obtained by high-temperature shear grinding of waste tire crumb rubber. ABCD results of RTFO-aged samples showed clear and gradual decrease of the ABCD cracking temperature (improvement) for all BC as the modifier concentration increases. It is noteworthy that the Bitumen Composites (modified bitumens) were cracking at higher strain and fracture stress values compared to neat bitumen. Results of DSR-4 mm test showed a decrease in the complex shear modulus (G*), storage modulus (G¢) and loss modulus (G²) BC compared to the neat bitumen. It is shown that bituminous composites have no maximum on the Cole-Cole diagram (dynamic vitrification) at T = -28°C which is observed in the neat bitumen.
