Rigid pavement structures are one of the costly components of the infrastructure development process. It consumes a huge quantity of ingredients necessary for concrete development. Hence, a newly introduced concept of circular economy in combination with waste management was introduced to solve this problem. In this study, three waste products (rice husk ash (RHA), wood sawdust (WSD), and processes waste tea (PWT)) was utilized to develop the concrete for rigid pavement structures by replacing the sand, i.e., a filler material at different percentages. During the testing procedure of compressive (CS), tensile (TS), and flexural strength (FS) properties, RHA and WSD at 5% replacement were found to be a good replacement of sand to develop required concrete. This study will help in the production of eco-friendly rigid pavement structures and a pathway of life cycle assessment in the future.

Mechanics properties of lime- fly ash stabilized soil are investigated. First, the chemical composition of fly ash are analyzed by spectral analysis test. Compaction experiments of all mix proportion projects are carried out in different water conditions to obtain the optimum water contents. Then the optimum mix proportion is obtained by the unconfined compressive strength and the compression rebound modulus test. Finally, the pavement structures design for a highway of lime- fly ash stabilized soil road sub-base is done. By the comparison, a conclusion can be drawn that lime-fly ash stabilized soil is suitable for flexible pavement or semi-rigid pavement because of its good strength and rigidity which can effectively reduce thickness of the lower pavement and basic deflection.

Due to the intensive process of road construction or rehabilitation of pavement caused by an increase in traffic volume, in the field of rigid pavement design and research in Romania, we can say that there is a need to improve the design method. In the last decade, more and more researchers have been concerned about climate change and the increase in traffic volume; hence, there is a need for a renewal of the climatological, as well as traffic, databases because these are part of the input data for the design process. The design method currently used in Romania for jointed plain concrete pavement design is NP081/2002. The limitation of the data and the lack of lifetime estimation of structural and functional performance are the main aspects that need to be addressed in the new design procedure. The Mechanistic–Empirical Pavement Design (MEPDG) method offers the possibility of the design of pavement structures by estimating the structural and functional performances. This paper aims to obtain a comparative study of these two methods for the analysis of the input data collected from the field corresponding to the three failure criteria, while the symmetry of the characteristics of the material and their asymmetrical thicknesses are compared, thus contributing to the design of viable and long-lasting pavement structures using a rigid pavement with the specific characteristics of the mountainous area in northeastern Romania on the national road DN17 Suceava—Vatra Dornei. The novelty of this study consists of the implementation of the mechanistic–empirical method MEPDG instead of the old NP081/2002 method used in Romania.

Flexible, rigid, and paving block pavements can be used as alternative roads because the soil conditions on the Pantai Utara Flores road are rocky soil with a relatively high CBR so that the most important role in withstand load is subgrade. The purpose of the Comparison of Construction and Costs for Flexible, Rigid, and Paving Block Pavement Structures on Jalan Pantai Utara Flores is to know which one most effective and efficient when viewed from the traffic load  with each  pavement using the Bina Marga method, AASHTO , and Direktorat Jendral Bina Marga. Jalan Pantai Utara Flores is access to Komodo Labuan Bajo airport which is a Class I road, rocky land with a relatively high CBR, rainfall of Labuan Bajo is relatively low, LHR in Labuan Bajo is relatively small, besides Labuan Bajo is a tourist area that should be supported  by road access that has driving comfort so the suitable pavement structure for Jalan Pantai Utara Flores is flexible pavement. Meanwhile, based on the recapitulation of the analysis results, the cost of flexible pavement is Rp. 28,793,604,705,600, the cost of a rigid pavement  is Rp. 34,218,430,585,828 and  the cost of paving block pavement  is Rp. 17,410,645,080,000 so it can be seen that the paving block pavement is most economical, but the paving block pavement structure has a very uncomfortable driving comfort besides that the paving block pavement structure cannot be passed by vehicles at high speed so that the paving block pavement structure is more suitable for controlling speed of vehicles such as roads in crowded urban areas and residential roads.

To sustainably eradicate corruption, extraordinary efforts are needed particularly in the context of construction projects. In this study, the state losses in government-funded construction projects in Indonesia is analyzed. Research data were collected through field observations for types of work that were not completed per technical specifications. Data analysis was performed using descriptive statistics. The results indicate that structural work was responsible for 98.70% of total state losses. The top three state losses were found to be associated with concrete, roads, and front stonework, and the values are 40.40%, 28.43%, and 18.23% respectively. Loss in architectural work was the smallest (1.30%). The outcomes of this survey offer a knowledge basis for law enforcement authorities and construction project supervisors to pay more attention to projects involving concrete structures, rigid pavement structures during road construction, and stonework.

AbstractThe paper analyses the influence of seasonal temperature variations on fatigue strength of flexible and semi-rigid pavement structures chosen for KR4 traffic flow category. The durability of pavement determined assuming a yearly equivalent temperature of 10°C and assuming season-dependent equivalent temperatures was compared. Durability of pavement was determined with the use of Asphalt Institute Method and French Method. Finite Element Method was applied in order to obtain the strain and stress states by the means of ANSYS Mechanical software. Obtained results indicate a considerable drop in pavement durability if seasonal temperature variations are considered (up to 64% for flexible pavements and up to 80% for semi-rigid pavements). Durability obtained by the French Method presents lower dependence on the analysed aspect.

Mechanics properties of lime-steel slag stabilized soil for pavement structures are investigated. Firstly, the chemical composition of the fine grain steel slag is analyzed by spectral analysis test. In view of the materials compositions, 5 kinds of mix proportion projects are defined. Compaction tests of all mix proportion projects are carried out in different water conditions to obtain the optimum moisture contents. Then the optimum mix proportion project is demarcated by the unconfined compressive strength test and the compression rebound modulus test. Finally, the pavement structures design for a highway of lime-steel slag stabilized soil road sub-base is made. As comparisons, the pavement structures of other types of lime industrial wastes stabilized soil road sub-base are computed. It is shown that lime- steel slag stabilized soil is suitable for flexible pavement or semi-rigid pavement because of its good strength and rigidity which can effectively reduce thickness of the lower pavement and basic deflection.

The paper describes research works of interlayer bonding of asphalt layers conducted at Gdansk University of Technology. The studies included laboratory and field tests, and calculation of pavement structures with different interlayer bonding models. Laboratory tests included interlayer bonding tests using the direct shear method which evaluated the influence of selected factors on interlayer bonding: the type and the amount of the emulsion, the method and the effectiveness of compaction, vulnerability to dirt, water and repeated shear loads. Field works were focused on the impact of interlayer bonding of asphalt layers on the deflection of pavement structure and the back-calculated stiffness modulus of asphalt mixtures. The analyses of the field tests also included the impact of the asphalt layers compaction ratio on interlayer bonding. Computational analyses of asphalt pavement structures consisted of the simulation of different interlayer bonding in a multi-layered elastic half-space. Calculations were also made by using the finite element method within cohesion and friction models to simulate interlayer bonding.
