“…Pre-stressed Pavement Concrete: The road surfaces are found to have better durability and load bearing capacity when the pavements are created from prestressed concrete that is a type of modern construction approach. This technique involves pre-tensioning or post-tensioning steel tendons within the concrete before it sets, applying a compressive stress that counteracts the tensile stresses exerted by traffic loads and environmental factors [29]. Prestressing the concrete in this manner allows the pavement to handle greater loads and resist cracking more effectively than traditional concrete surfaces.…”

Urbanization has increased significantly during the last century, affecting both rural and urban areas. Due to the growing need for improved connectivity and services, roads and other transportation infrastructure are being built quickly. To meet this need, scientists, designers, and builders have been investigating novel and reasonably priced manufactured goods with the goal of streamlining the building process and improving overall robustness. In recent times, concrete pavements have witnessed a surge in popularity in India, driven by the escalating costs associated with bituminous pavement. The main benefit of using stiff pavement is that it is resilient and can hold its form even under harsh weather and traffic situations. Although concrete pavements may have a higher initial cost, they frequently wind up being more economical in the long run since they require less upkeep and have an excellent design life. This study's primary objective is to present a comparative analysis of pavement appropriateness while accounting for longevity, durability, and cost-effectiveness, among other factors. The simulation can be utilised to gain a quantitative understanding of the dynamic strains and deflections present in a rigid pavement and flexible system. It is discovered that the impact of surface roughness on a slab structure's dynamic response is significant for the pavement structure's useable life span and can be taken into consideration during pavement design. The model can be adjusted to determine the k-value needed to assess a pavement's subgrade support as it ages.

“…The concrete pavements or concrete overlays have proven performance across the globe with their initial cost high, whereas the maintenance cost of these pavements is less as the failures are relatively shorter when compared with bituminous concrete pavements or overlays. The life cycle cost analysis, which is the sum of initial cost, maintenance cost and vehicle operating cost for the concrete pavements, proved economical when compared with bituminous concrete pavements from the research (Jundhare and Khare, 2013). The cement concrete overlay on the existing bituminous concrete pavement, which needs maintenance, is called white-topping, making the pavement durable and further sustainable.…”

Purpose The ultra-thin white topping (UTW) is a cement concrete overlay of the thickness of 50–100 mm on bituminous concrete pavements with surface failures. This is a long-lasting solution without having short-term failures. This paper aims to design an ultra-thin cement concrete overlay using a developed critical stress model with sustainable concrete materials for low-volume roads. Design/methodology/approach In this research paper, a parametric study was conducted using the ultra-thin concrete overlay finite element model developed with ANSYS software, considering the significant parameters affecting the performance and development. The non-linear regression equation was formed using a damped least-squares method to predict critical stress due to the corner load of 51 kN. Findings The parametric study results indicate that with a greater elastic modulus of bituminous concrete, granular layer along with 100 mm thickness of concrete layer reduces the critical corner stress, interface shear stress in a significant way responsible for debonding of concrete overlay, elastic strains in the pavement further the concrete overlay can bear infinite load repetitions. From validation, it is understood that the non-linear regression equation developed is acceptable with similar research work done. Originality/value From the semi-scale experimental study, it is observed that the quaternary blended sustainable concrete overlay having a high modulus of rupture of 6.34 MPa is competent with conventional cement concrete overlay in terms of failure load. So, concrete overlay with sustainable materials of 100 mm thickness and higher elastic modulus of the layers can perform in a sustainable way meeting the environmental and long-term performance requirements.
