Article presents the comparison of performance of selected road sections in north-eastern Poland constructed under typical contract conditions, with the usage of High Modulus Asphalt Concrete and typical Asphalt concrete The field investigation comprised of the assessment of: the number of transverse thermal cracking, the bearing capacity and the load transfer coefficient around the thermal cracks. The FWD test confirmed lower deflections of the road sections constructed with base courses made of High Modulus Asphalt Concrete and presented two times higher values of the stiff ness modulus of those pavements. The load transfer coefficient for pavements constructed with base course made of High Modulus Asphalt Concrete indicated almost lack of load transfer around the thermal cracks. In was very surprising as the tested roads were quite new (2-7 years) and with high bearing capacity. The article was made on the basis of the paper presented on BESTInfra conference, which was held in Prague.

The Street-Race Circuit is being built in the Mandalika Tourism Special Economic Zone (KEK), Central Lombok, West Nusa Tenggara. The construction is targeted to be completed, before the MotoGP event on this circuit is implemented in 2021. One of the infrastructure related to this, which also really needs to be built to support the smooth running of the 2021 MotoGP is the development of access to the circuit location. The analysis carried out includes the calculation of heavy equipment productivity. Heavy equipment productivity is determined based on cycle times, production per hour, number of heavy equipment used, the amount of operating costs per hour. The analysis was carried out for the road surface layer work, namely the Asphalt Concrete Base Course (AC-BC) work. Based on the results of the analysis, it was found that the production for 1 unit of asphalt mixing plant (AMP) was 49.80 tons/hour and 9 units of dump trucks were 2.34 tons/hour. The spreader using the asphalt finisher can spread 109.18 tons/hour. As for the compactor, which is 18.55 tons/hour for 2 units of tandem rollers and 27.47 tons/hour for 1 unit of pneumatic tire roller. Other equipment is 9.96 m2/hour for air compressor and 2.74 liter/hour for asphalt sprayer. Meanwhile, in the Asphalt Concrete Wearing Course (AC-WC) work, several tools have the same productivity as the AC-BC job, namely asphalt mixing plant, air compressor and asphalt sprayer. Meanwhile, 13 units of Dump Trucks amounted to 2,338 tons/hour, 1 unit of asphalt finisher of 72,787 tons/hour, 3 units of tandem rollers of 12,367 tons/hour, and 1 unit of pneumatic tire roller of 18.31 tons/hour. The total cost of using heavy equipment for road surface layer work is Rp. 4,967,657,344. The total cost based on the contract document is Rp. 5,042,082,622. So that there is a difference in costs of Rp. 74,425,278.

The paper presents the analysis of the monitoring system of the embankment supported on concrete columns and overlaid by a load transfer platform with the embedded steel grid. This field investigation was to study the complex interaction between the columns, the load transfer platform layer, and steel grid via in situ measurements during erection and live loading of the embankment. The study was focused on the behaviour of steel grid and the behaviour of the outer rows of columns since there are limited reference data available for this problem. The system was designed to inform the engineers about the condition of the embankment at every stage of construction and during standard operation of the road. The measurements brought the information on strain variations of steel grid, concrete columns, and structural settlement and provided necessary evidence for the embankment numerical model validation.

Pavement Construction

According to the European Asphalt Pavement Association, more than 90 per cent of the European road network is paved with asphalt. Constantly increasing traffic volume and climate change accelerate deterioration of current pavements. As a result, there arises a need to rehabilitate them prematurely. Repair and rehabilitation work lead to traffic congestion, which is one of the most significant concerns in highly trafficked roads and urban streets. Concrete modular pavements consisting of precast concrete slabs are a reasonable solution to deal with the road works since their construction, as well as repair, is time-saving. Repair works typically are implemented during a low traffic period (usually at night). A primary purpose of concrete modular pavements is heavily trafficked roads and other transport areas. This paper focuses on concrete modular pavements, their types, issues and challenges related to their design, slab fabrication and pavement construction. The conducted analysis revealed 15 different types of concrete modular pavements that differ from the techniques of slab joints and load transfer between the adjacent slabs. More than 20 issues and challenges related to the design of modular elements, slab fabrication and pavement construction were identified. Finally, the existing practice of concrete modular pavements was summarised and the gaps of scientific knowledge, as well as a need for comprehensive research, were defined.
