“…In this study, the proposed pavement structure primarily includes an additional RBL between the base and the asphalt layer, as illustrated in Figure 1. This design is specifically intended to mitigate the surface cracking resulting from the semi-rigid base's cracking, enhance the mechanical behavior of the pavement structure, and ultimately prolong the pavement's service life [16,17].…”

This study aims to summarize design indexes for rich bottom layer mixtures (RBLMs) and design asphalt mixtures with superior performance to reduce reflective cracks and fatigue cracking resulting from semi-rigid base cracking in the asphalt layer. First, this study synthesizes the research results about RBLMs and introduces the related design indexes. After that, using ABAQUS 6.13, finite element analysis was performed to analyze the change in bottom stress when the base cracked and the interlayer bond weakened. SBS-modified asphalt mixtures (SMMs) and composite-modified asphalt mixtures (CMMs) were subsequently developed as RBLMs utilizing the Marshall test method and applied on a test road. The research findings reveal that design indexes for RBLMs include a volume of air voids (VVs) within the range of 2.0–3.0%, a maximum flexural strain exceeding 3500με, and a dynamic stability surpassing 1000 cycles/mm. Both mixtures satisfy the design requirements, with the CMM demonstrating superior performance and offering promising application prospects. Future research endeavors will concentrate on prolonged monitoring of the test section to authenticate the effectiveness of an RBL in practical road applications.

“…Maintenance activity and scheduling of perpetual flexible pavement over a 50-year period as shown in Figure 4 are done with the reference of the study article "Design of Optimal Perpetual flexible pavement Structure". According to a total of 3,213 Mechanistic-Empirical Pavement Design Guide (MEPDG) simulations, the deployment of perpetual pavements should include a resurfacing plan every 10 years to remove rutting in the top surface [18]When comparing the two pavements, just that layer with a different value is chosen for quantifying cost and emission.…”

India needs roads that can handle a large volume of traffic and have a long service life due to the scarcity of natural resources and their rising cost. Over the last decade, type. As a result, the notion of a perpetual flexible pavement with a life of more than 50 years and great structural capacity has emerged. Perpetual flexible pavement has a direct competition with cement concrete-based rigid pavement. The comparison of life cycle cost (LCC) and life cycle environmental cost (LCEC) is an analytical method for determining the long-term viability of any pavement. This paper examined the overall sustainability of each pavement by comparing (1) the life cycle cost with the help of net present value (NPV) method and (2) life cycle environmental cost considering greenhouse gas emissions from various activities in construction and maintenance of pavements over a 50-year analysis period. The cross-sections of the Delhi-Mumbai expressway with perpetual flexible pavement and the Mumbai-Pune expressway with conventional rigid pavement, both of which have been designed for a long service life and a good structural capability were chosen for the investigation as a case study. The findings of the present study reveal that the per kilometre life cycle cost of perpetual flexible pavement is 2.12 lakh rupee less than the rigid pavement. Also, perpetual pavement emits 4.5 times less greenhouse gases than rigid pavement over their design life. In comparison to a rigid pavement during a 50-year design life, the study concludes that perpetual flexible pavement is not only economically effective but also environmentally sustainable

“…In consequence, the method seeks to avoid a terminal structural condition, and the damage ratio as(𝐷 = 𝑁 𝑒𝑥𝑝𝑒𝑐𝑡𝑒𝑑 𝑁 𝑎𝑙𝑙𝑜𝑤𝑎𝑏𝑙𝑒 ⁄ ) must be lesser than 1.0 (Timm, Robbins, Tran, & Rodezno, 2014). Accordingly, these pavements are expected to perform for 50 years without major structural rehabilitation or reconstruction (Tarefder & Bateman, 2012).…”
