An immense problem affecting environmental pollution is the increase of waste tyre vehicles. In an attempt to decrease the magnitude of this issue, crumb rubber modifier (CRM) obtained from waste tyre rubber has gained interest in asphalt reinforcement. The use of crumb rubber in the reinforcement of asphalt is considered as a smart solution for sustainable development by reusing waste materials, and it is believed that crumb rubber modifier (CRM) could be an alternative polymer material in improving hot mix asphalt performance properties. In this paper, a critical review on the use of crumb rubber in reinforcement of asphalt pavement will be presented and discussed. It will also include a review on the effects of CRM on the stiffness, rutting, and fatigue resistance of road pavement construction.

There are two processes of adding crumb rubber modifier (CRM) to hot mix asphalt (HMA), that is, the wet process and the dry process; and different technologies are available for each process. On the basis of the results of the binder study and producer's practices, HMA specimens were prepared using two selected AR binders with Producer R and A CRMs for Rhode Island (RI) dense-graded and dense-graded friction course (DGFC) mixtures, respectively. Aggregates procured from four local asphalt contractors were used. In addition, gap-graded HMA specimens were prepared with 3 percent CRM and control AC-20 binder with two typical local aggregates using the dry process. Marshall mix design was performed on all mixtures to determine optimum binder content and Marshall properties. Mechanical properties were evaluated for the mixtures with and without CRM. Superpave Level I mix design was also performed for dense-graded, DGFC, and gap-graded mixtures with aggregates procured from Contractor C. Finally, the performance of pavements with and without CRM was predicted using the computer program VESYS. Results of this study indicated that the use of CRM is feasible for RI dense-graded and DGFC mixtures utilizing the wet process.

The paper characterizes the porous asphalt mixture used in pavement construction. This kind of pavement can reduce traffic noise and reduce the slipperiness of the road pavement. The effectiveness of the porous asphalt depends on many design and technological aspects, but especially on the air-void clearance in the pavement layer. The paper includes the results of water permeability research based on laboratory tests of specimens from actual road pavement. The research shows the differences between the contamination of the road pavement sections located inside and outside the city. The paper includes recommendations for using porous asphalt based on experiences under Polish conditions.

Crumb rubbers (CRs) have been proposed as pavement components because they are waste materials. Previous studies have attempted to find alternative material in pavement construction that act as additives or property modifier. The current study presents a laboratory experiment using CR recycled from discarded vehicle tiresas additives in hot mix asphalt (HMA). CR was added using the dry process technique. Three rubber sizes were used with the following measurement: 0.15, 0.425, and 1.18mm. CR was added 2% of the weight of total aggregates. Bitumen80/100 penetration was used throughout the experiment. The effect of CR size on the mixture was investigated in terms of resilient modulus, indirect tensile strength (ITS), stability and dynamic creep. Experimental results revealed that the four engineering properties decreased when CR was added to HMA and when CR size was increased. However, the increasedCR size similarly increased the permanent deformation values. The data analysisshowed that 0.15mm CR is the most effective material for asphalt mixturebecause of the partial interaction between rubber particles and bitumen.

Pavement Construction

Hot mix asphalt (HMA) is produced and laid at high temperature and therefore it is subjected to segregation due to differential cooling, which usually occurs during asphalt material transportation and road pavement construction. If mixing temperature is inconstant the degree of compaction may vary, and this will inevitably result in poor performance of the newly laid road pavement. This study describes factors influencing the quality of asphalt pavement construction and analyses results of repair of the selected road section using the solutions of the asphalt mix compaction control technology with the aim to increase the service life of road pavement and to reduce construction costs. Data were obtained by the asphalt pavement compaction control system TOPCON C-63A built in the HAMM company rollers HD- 75 and HD-120 used at the paving site, and by the TROXLER 3451 device used for the self-control density measuring tests. The data obtained enabled to determine the number of rolling passes, temperature differentials of asphalt pavement and pavement compaction.

Pavement Construction

Paved surfaces must reliably bear heavy loads, often under challenging environmental and geotechnical conditions. These requirements are addressed through the use of high-quality, newly produced materials in pavement design. However, in remote locations, newly produced materials are often expensive or unavailable, making waste or alternative materials more attractive. Waste materials can be used in their natural condition but are more commonly stabilised or otherwise improved to meet performance targets. However, this practice can incorporate unwarranted risk into pavement design solutions. The decision to use waste materials in a pavement is a balance between technical risk, maintenance liability, available materials, environmental emissions and capital cost. This study reviews the use of waste materials in pavement design and construction. Reclaimed asphalt pavement (RAP) materials and processed waste plastic for pavement construction are considered. Additionally, blast furnace slag (BFS) and waste glass in pavement construction are evaluated. This review focuses on the effects of alternative materials on the properties of asphalt pavement. The results indicate that RAP is acceptable as an alternative material, while BFS, waste plastic and waste glass can be used under specific conditions. Also, the current and future challenges for the use of waste materials in the pavement industry are discussed.

Today, rapid economic and industrial growth generates increasing amounts of waste materials such as waste tyre rubber. Attempts to inspire a green technology which is more environmentally friendly that can produce economic value are a major consideration in the utilization of waste materials. The aim of this study is to evaluate the effect of waste tyre rubber (crumb rubber modifier (CRM)), in stone mastic asphalt (SMA 20) performance. The virgin bitumen (80/100) penetration grade was used, modified with crumb rubber at four different modification levels, namely, 6%, 12%, 16%, and 20% by weight of the bitumen. The testing undertaken on the asphalt mix comprises the indirect tensile (dynamic stiffness), dynamic creep, and wheel tracking tests. By the experimentation, the appropriate amount of CRM was found to be 16% by weight of bitumen. The results show that the addition of CRM into the mixture has an obvious significant effect on the performance properties of SMA which could improve the mixture's resistance against permanent deformation. Further, higher correlation coefficient was obtained between the rut depth and permanent strain as compared to resilient modulus; thus dynamic creep test might be a more reliable test in evaluating the rut resistance of asphalt mixture.
