“…An effectively jointless length can be up to 99 m. In general, three systems of PPCP exist depending on the stressing: central stressing, end stressing at surface and end stressing at vertical joint face (Merritt et al, 2000(Merritt et al, , 2002Merritt, McCullough, & Burns, 2005;Merritt, Rogers, & Rasmussen, 2008;Mishra, French, & Sakkal, 2013). Each system is described in details by Vaitkus, Gražulytė, Kleizienė, Vorobjovas, and Šernas (2019). JPCP consists of reinforced or prestressed slabs that are connected together on the project site using different systems of dowel bars and slots.…”

Roads and other trafficked areas infrastructure starts to deteriorate as far as it is opened to traffic. Thus, it has to be timely repaired and reconstructed. However, any interruption to traffic by implementing repair and rehabilitation works leads to user's discomfort and traffic congestion. Modular pavements also known as precast concrete pavements can be constructed at night, consequently they eliminate or reduce traffic flow limitation related to repair works. They consist of prefabricated concrete slabs that are transported to the construction site only after the curing period when the desirable concrete strength is achieved and installed on a prepared foundation. Slabs prefabrication in a plant results in better concrete quality, controlled concrete curing conditions, wider period for pavement construction, reduced time before opening to traffic, elimination of early-age failures and material segregation which may occur during concrete or asphalt mixture transportation to the project site and laying. Despite these advantageous, modular pavements are barely used in Europe. In order to enhance the usage of modular pavements in Europe, paper focuses on the identification of the most promising modular pavements application areas and their type selection. The most promising application areas such as motorways and arterial streets were identified on the basis of the conducted survey among high qualified researchers. Low volume roads, private roads, bicycle and pedestrian paths could be included as modular pavements special application areas with slightly different approach.

“…Researchers have developed at least 11 systems of PCP based on the JPCP concept. Each system is described in details by Vaitkus et al (2019). The main differences between them are the techniques to connect the adjacent slabs in order to get more efficient load transfer (>90%) and to level the slabs.…”

“…It is significantly important for concrete modular pavements, also known as precast concrete pavements (PCPs), since the thickness affects the transportation and lifting cost of slabs and, at the same time, the whole construction cost. It is noted that those pavements differ from other types of concrete pavements by production (construction) process: PCPs are constructed of prefabricated slabs that are transported to the project site from the plant only when the desired concrete strength is achieved, while other types of concrete pavements are cast-in-place and the concrete mixture cures on-site [ 6 ]. PCPs, like other concrete pavement types, are suitable for all types of application areas, i.e., roads, streets, aprons and taxiways, logistic terminals, low volume and private roads, as well as bicycle and pedestrian paths [ 7 ].…”

Usually, C30/37 strength class concrete is used to construct concrete pavements on a rigid, semi-rigid or flexible base. Concrete with such a strength delivers essential design characteristics: flexural strength and tensile splitting strength are between 4.5–5.4 MPa and 2.8–3.7 MPa, respectively. Design characteristics can be significantly increased by densifying the concrete mixture, i.e., adding silica fume, steel or polypropylene macro fibers. As high-performance concrete characteristics are 20–60% higher than those for standard concrete (C30/37), new possibilities to reduce the thickness of concrete pavement slabs appear. The theoretical analysis of concrete pavement structures with high-performance concrete mixtures (C40/50, C45/55 and C50/60) showed that slab thickness could be reduced by 6–39% compared to a standard concrete pavement structure depending on the concrete properties and design method. From all those pavement structures, three concrete mixtures were determined as the most rational ones in terms of PCP thickness reduction and total pavement cost: (i) with 49.5 kg/m3 of steel fibers and 25.2 kg/m3 of silica fume; (ii) with 10.0 kg/m3 of polypropylene fibers (type A); (iii) with 49.5 kg/m3 of steel fibers.

“…The decision-making concept of Life Cycle Cost Analysis (LCCA) is based on the evaluation of long-term economic efficiency between two or more alternative investment options (Walls III & Smith, 1998). One of the promising alternatives of traditional pavements is the modular pavement technology also known as precast concrete pavement (PCP) (Tayabji & Tyson, 2014;Tayabji, Ye, & Buch, 2014;Vaitkus, Gražulytė, Kleizienė, Vorobjovas, & Šernas, 2019). Kohler, du Plessis, Smith, Harvey, & Pyle (2007) stated that PCP used for highways, roads, bus lanes, interceptions, parking lots, tunnels, aprons and port pavements as well as repair of traditional concrete pavement.…”

“…• reduced risk of joint ravelling. There are several types of PCP with slab dimensions, reinforcement and jointing (Vaitkus, Gražulytė, Kleizienė, Vorobjovas, & Šernas, 2019): precast pre-stressed concrete pavement, JPCP, incrementally connected PCP. Design of PCP is based on the assumption that the overall service conditions of PCP (traffic loading and environmental effects) will be similar to the cast-in-place JPCP (Smith & Snyder, 2017;Tayabji & Tyson, 2014).…”

Mechanical properties and slab dimensions of concrete are the major parameters based on which the performance of concrete pavement structures is predicted. Precast concrete pavement, as one of the most common modular pavement type, is the advanced next-generation technology characterised as high quality, durable, quickly built and easily maintained. The service conditions of precast concrete pavement (traffic loading and environmental effects) are similar to the conventional cast-in-place jointed plain concrete pavement. Thus, the precast concrete pavement structural design is similar to that of jointed plain concrete pavement. There are several concepts for the design of concrete pavement structure. However, they are based on different distress evaluation and critical stresses estimation methods assuming the slab dimensions that for jointed plain concrete pavement are within the wide joint spacing range from 3.5−6.0 m. The objective of this paper is to analytically evaluate the effect of concrete mixture mechanical properties on the thickness and dimensions of precast concrete pavement slab. Also, define the minimal thickness of precast concrete slab dependent on slab dimensions and concrete mixture mechanical properties elastic modulus and tensile splitting strength. The analysis is based on bearing capacity, performance and fatigue boundary conditions as reported by semi-probabilistic pavement design method Richtlinien für die rechnerische Dimensionierung von Betondecken im Oberbau von Verkehrsflächen RDO Beton 09. Considering that, concrete mixture has significant effects on pavement performance; the composition of concrete was also discussed in this paper. The optimal slab dimensions, concrete layer thickness, and base layer type is suggested in this paper. The outcomes of this analysis apply to the production of precast concrete pavement slabs.
