Introduction:The use of polymer wastes in pavement as road is an increasing trend in the road construction sector. Those new pavements reduce the amount of solid waste disposed into landfills and provide more sustainable construction due to the use of in-situ materials. Polyurethane foam waste is a thermostable polymer being used in the form of a grey-coloured foam, a by-product of the automobile industry.Aim:The focus of this work centers on the exploitation of polyurethane foam waste in full or partial substitution of the fines and the mineral powder that form the bituminous mixtures to produce a sustainable alternative for bituminous asphalt used in pavement construction.Methods:A series of specimens were manufactured and tested for the Marshall test, with different percentages of polyurethane foam waste aggregates (50% and 100%), calculating their apparent densities.Results:The results show acceptable compatibility between the elements of bituminous concrete and the polyurethane waste, producing a reduction in both the apparent density and Marshall stability, as well as an increase in volume and an increase in deformation with higher volumes of waste in the mixture.

In Indonesia, the road construction has experienced a fairly good development. From a wide range of road constructions, flexible pavement is the most chosen one because its characteristics: easy, fast, and efficient. However, flexible pavement has many weaknesses, for example the premature damage on the road surface after some time passed by the traffic so that the road cannot reach the planned age. For that, it is done a research to add a hot asphalt mixture material that aims to improve the quality of the mixture results. The selected ingredient is natural water hyacinth. The method used is trial and error with reference of SNI 03-1737-1989. Variations used are 2%, 4%, 6%, 8% and 10% of the asphalt weight, asphalt level used is 5.72 %. Of the 5 variations of mixture used on Type XI Asphalt Concrete Layer, it is obtained the result that the water hyacinth fiber level which has the best score and meet the specifications of SNI 03-1737-1989 is on the percentage of 6% which obtained from calculation data using graphs and regression model where Marshall Stability is equal to 644,46 Kg, flow 3,39 mm, VMA (voids in the mineral aggregate) is equal to 13,83 %, VFWA (voids filled with asphalt) is equal to 65,35%, VIM (voids in the mix) is equal to 2,52 %, density of 2.31 gr/cc, and Marshall Quotient of 164.03 Kg / mm.

Today the use of Construction and Demolition Materials (CDM) can be considered as a suitable solution for the construction or the rehabilitation of road pavements. In this context, it is central to minimizing waste production, favoring the reuse through new production cycles to replace virgin natural raw materials. As illustrated in this study, steel slag has mechanical properties that justify its use as aggregate in the manufacture of bituminous mixes. In road construction, their use is focused on the substitution of fine aggregate and filler in bituminous mixtures. Mechanical characterizations, Marshall stability and indirect tensile resilient modulus (ITSM) tests were used to evaluate the laboratory performance of the mixtures. The research aims are to provide the use of these materials for the construction of the entire road pavement structure; in this study authors used these materials both in the characterization of cementitious layers and in those with bituminous conglomerate. In both cases, the use of steel slag has favored an increase of stiffness in the mixtures.

Abstract The utilization of industrial waste products to produce asphalt concrete for road construction was investigated. Aggregates were partially replaced with aluminum slag (AS) and crushed ceramic tiles (CCT) at 10%, 20%, 30%, 40%, and 50% by weight. Physical tests were performed on the aggregates, while a flash and fire point test as well as penetration tests were carried out on the bitumen. Similarly, Marshall stability tests were conducted on cylindrical specimens of the asphalt concrete. The average values of 18.88 and 30.69 obtained for the aggregate impact value (AIV) and aggregate crushing value (ACV) were satisfactory for road surfacing when compared with the specification. Marshall stability values of 10.84 KN, 4.27 KN, and 3.21 KN respectively were obtained with 30%, 20%, and 50% partial replacements with AS. The percentages were suitable for heavy, medium and light traffic when compared with the Marshall design criteria provided by the Asphalt Institute. The use of aluminum slag and crushed ceramic tile could reduce the large volume of industrial waste and the cost of pavement construction and maintenance.

Road safety has become a serious issue in both developed and developing countries, costing billions of dollars every year. Road accidents at nighttime especially in low illumination situations are common and severe and have gained a lot of attention. To improve visibility and avoid traffic accidents, a series of efforts have been made but the existing mechanism is facing continuous challenges and highlighting a need for smart highways with high efficiency, road safety, and strength. In this study, the use of radium polymer beads (RPB) is proposed to avoid road accidents. The effect of RPB was investigated by comparing the results of the beads’ surface and modified asphalt mixtures using the three-stage testing methodology. Utilizing the circular economy, RPB have been introduced as a solution to the problem. Results indicated that in the first phase, the addition of RPB on the mixture surface improved the mechanical performance of the road pavement and helped in avoiding road accidents due to their ability to absorb the light from the source and then reflect in the night. Moreover, the mechanical properties using Marshall stability standard parameters (stability 9 kN and flow 2–4 mm range) were fulfilled as a standard testing requirement. The proposed radium bead layer can reduce road accidents and provide a direction towards future smart highways by using new reflective materials in road construction.

Road construction is an activity that involves a large consumption of raw materials, with the consequent high environmental impact. For this reason, various research projects are being developed in which waste is used as a raw material for bituminous mixtures. This avoids the extraction of raw materials, reduces the environmental impact and reduces greenhouse gas emissions. In this research, the incorporation of ladle furnace slag as a filler for continuous grading bituminous mixtures was evaluated. Firstly, the ladle furnace slag was chemically and physically characterised and its suitability for use as a filler was determined in accordance with the regulations. Subsequently, bituminous mixtures were conformed with the slag and also with commercial fillers, calcareous and hornfels, in order to compare the results. Finally, the physical properties, Marshall stability and the effect of water were determined with the immersion–compression test on all families of samples. The results showed that the mixes conformed with ladle furnace slag had higher Marshall stability, less variation due to the effect of water and acceptable physical properties. Consequently, the suitability of utilisation of these slags in bituminous mixtures could be confirmed.

Pavement planning is good, because in this way the pavement construction is able to carry the load of vehicles passing on it and spread the load to the layers beneath it, including the subgrade, without causing significant damage to the road construction itself. The purpose of this study is to obtain the most efficient alternative pavement thickness index and to obtain the required cost and time. The results showed that the Pavement Thickness Index (ITP) using the Bina Marga Method = 7.48 and the 1993 AASHTO Method = 10.20 had a difference of 2.72. The difference in Pavement Thickness Index (ITP) resulted in the addition of pavement thickness using the 1993 AASHTO Method. The economical Pavement Thickness Index (ITP) was the ITP Bina Marga Method with a construction cost of Rp 12.7 billion, with savings of Rp 3.8 billion. By determining the pavement thickness at the same base layer = 20 cm, it is found that the type of material is Aggregate Class B, CBR is 80% cheaper than cement + CTRB with savings of Rp 913,991,544, - ~ 1 billion. The time required in implementing the Bina Marga Method is more efficient than the 1993 AASHTO Method with a savings of 44 days, this is due to cement work + CTRB = 15 + 29 = 44 days. While Aggregate Class B, CBR 80% only takes 22 days, thus saving 22 is also due to the larger ITP of the 1993 AASHTO Method so that it requires additional thickness of the base layer under Aggregate Class C, CBR 30% of 22 cm thus increasing the duration of the implementation time by 24 days

Abstract. Application of rigorous construction procedures is fundamental when it comes to road construction. Nowadays, and in particular in Chile, the asphalt paving construction process is based on tradition, craftsmanship and other implicit, experience-based methods employed during road construction. This means, that the different stages of the construction process, including the paving of the road, are not controlled on time as they should, which causes that the final product does not have the ideal characteristics for which the construction materials initially were designed and manufactured. Therefore, we propose the use of tools and methodologies that allow monitoring each of the stages of the construction process in almost real-time. Our approach aims to evaluate the use of Remotely Piloted Aircraft Systems (RPAS) during the asphalt pavement construction process by capturing images and videos during the placement of the asphalt mixture and the movement of the compaction machinery (pneumatic roller and drum roller) present in the construction site. The observations are digitally processed by mainly binarization and thresholding. As a result, the macro texture of the asphalt surface was estimated and the trajectory of the compaction rollers was visualized. In conclusion, our results reveal that the main factor that influences the quality of the roads corresponds to the performance and operations of the compaction machinery.

Padadasarnya jalan akan mengalami penurunan fungsi strukturalnya sesuai dengan bertambahnya umur. Jalan Raya saat ini mengalami kerusakan dalam waktu yang relatif sangat pendek (keruskan dini) baik jalan yang baru dibangun maupun jalan yang baru diperbaiki. (Fadhilah,2012). Banyak hal yang menyebabkan kerusakan pada konstruksi jalan, anatara lain akibat pengaruh beban lalu lintas kendaraan yang berlebihan (over loading), temperatur, air (genangan), dan konstruksi perkerasan yang kurang memenuhi persyaratan teknis. Faktor lain seperti perencanaan, pengawasan, pelaksanaan dan lingkungan juga memberikan konstribusi pada kerusakan jalan.Deformasi pada perkerasan jalan lentur, yang biasa disebut (rutting dan geser), Alur biasanya terdiri dari lendutan memanjang yang terjadi pada jalur roda kendaraan, merupakan akumulasi dalam jumlah kecil terjadi deformasi disebabkan oleh adanya peningkatan beban. Kerusakan bisa berkembang lebih parah karena permukaan jalan tidak kedap air lagi sehingga air bisa melemahkan ikatan antara batuan dan aspalBahan tambah Derbo dan Wetfix dapat memperhambat laju deformasi pada campurn aspal beton.Basically, the road will experience a decrease in its structural function in accordance with increasing age. Roads are currently experiencing damage in a relatively very short time (early roll out) both newly built roads and newly repaired roads. (Fadhilah, 2012). Many things cause damage to road construction, among others due to the influence of excessive vehicle traffic loads (over loading), temperature, water (inundation), and pavement construction that does not meet technical requirements. Other factors such as planning, supervision, implementation, and the environment also contribute to road damage. Information on flexible pavement, commonly referred to as (rutting and sliding), Grooves usually consist of longitudinal deflections that occur in the lanes of vehicle wheels, constituting small amounts of accumulation deformation occurs due to an increase in load. Damage can develop more severely because the road surface is not waterproof anymore so water can weaken the bond between rocks and asphalt Derbo and Wetfix added materials can slow down the rate of deformation in the concrete asphalt mix
