SUSTAINABLE DESIGN OF PERVIOUS PAVER BLOCKS USING CEMENT KILN DUST (CKD) AND RECYCLED ASPHALT PAVEMENT (RAP) ·Abhyanshu Singh Rajawat1, Manoj Kumar Trivedi2 1Post Graduation Student, Department of Civil Engineering, MITS Gwalior, Madhya Pradesh, India 2Professor, Department of Civil Engineering, MITS Gwalior, Madhya Pradesh, India -------------------------------------------------------------------------***-----------------------------------------------------------------------strains everywhere else. Fatigue and rutting in asphalt Abstract
concrete are two major causes of failure in flexible pavement (2). Materials from asphalt and aggregate pavements that have been previously used and subsequently reclaimed are known as reclaimed asphalt pavement (RAP). High-quality, well-graded aggregates coated with asphalt cement can be found in RAP after it has been crushed and screened, and this material is mostly produced during pavement restoration and reconstruction (3). RAP quality might vary depending on the source of the old pavement it was recycled from and the qualities of the constituent materials and asphalt concrete type utilized in the original pavement. Sometimes new granular material, soils, or even garbage is added to heaps of recycled pavement. A variety of factors, including the frequency with which the pavement has been resurfaced, the extent to which it has been patched and/or cracked sealed, and the presence or absence of previous seal coat treatments, will affect the makeup of RAP. Specific gravity measurements of RAP indicate that it has a high silica content and low levels of CaO, falling within the range of 1.94 to 2.30. It is necessary to monitor the quality of recycled asphalt pavement (RAP) to ensure that it is suitable for its intended purpose after processing, since RAP may originate from a variety of sources. One prominent example is "in-place" recycling of asphalt roads. The usual particle size distribution and other physical, chemical, technical, and mechanical features of RAP have been determined via extensive research(4).
The main aim of the study is to make Sustainable and cost-effective development of pervious paver blocks made with CKD (Cement kiln dust) and RAP (Recycled asphalt pavement). In the present study, two different types of aggregates (CKD and RAP) were used: RAP aggregates and fresh aggregates (FA) that were procured from a nearby quarry. RAP was acquired through the uncontrolled milling of bituminous concrete (BC) pavement that was 8 years old and from a Gokul warehouse in Gwalior (M.P.). CKD was acquired as a cementitious replacement for the usage of industrial wastage for sustainability from the Rashi Prism factory in Satna (M.P.) A total of 70 specimens (14 types) + 5 replicas were made for testing in the lab. Two of the five replicates were tested for porosity, density, infiltration rate, and clogging impact; three were tested for strength properties (Compressive strength, Cantabro abrasion). According to the findings of the study paver blocks made from CKD are reliable as well as cost-effective. The finding concludes that paver blocks made by the replacement of CKD and RAP are sustainable, durable and affordable.

1. Introduction
The mining and heavy industrial industries, which include cement, power, steel, and others, are responsible for an increasing amount of waste. The expense of waste removal is rising as well. Without the creation and implementation of new and beneficial use choices that are both commercially viable and environmentally friendly, the accumulation of by-product materials is unavoidable. Cement kiln dust (CKD) is a solid waste product of Portland cement kilns' pre-heater by-pass systems caused by the presence of trace amounts of volatile components in the kiln's feed and fuel. The raw feedstock is only partially calcined, and the result is a fine, grey powder that resembles Portland cement. The main chemical components of CKD are lime, silica, alumina, and iron. The raw materials and collection
The construction of a reliable road system is crucial to a country's economic growth and social progress. Typically, the quantity of building supplies needed is quite large. Man makes use of soil for a wide range of construction-related tasks because it is the most inexpensive material at his disposal. Construction sites often lack access to graded soil, forcing engineers and scientists to make do with industrial waste that degrades the environment or presents disposal challenges. Use of waste materials in construction, such as fly ash, granulated blast furnace slag, cement kiln dust, etc., requires specific consideration in this setting (1). The granular material layer is an essential part of a flexible pavement structure since it affects the stresses and
