1. A PROJECT ON “ STUDY OF CONCRETE R IGID PAVEMENT Chichpalli J ambharla Road CH-2/800 TO 3/000 Taluka.Dist.Chandrapur DR.BABASAHEB AMBEDKAR TECHNOLOGICAL UNIVERSITY,LONARE UNDER THE GUIDENCE OF PROF.:P.M.BHAGATKAR DEPARTMENT OF CIVIL ENGINEERING RAJIV GANDHI COLLEGE OF ENGINEERING, RESEARCH AND TECHNOLOGY, CHANDRAPUR 2023-2024

2. PROJECT NAME :- STUDY OF CONCRETE PAVEMENT Following progress has done during this periods:- 1.Site cleaning 2.Excavation for subgrade 3.GSB(Granular Sub – Base) 4.PCC( Plain Cement Concrete) 5.PQC(Pavement Quality Concrete) Murum Thickness = 150 mm GSB THICKNESS =150MM Plain Cement Concrete = 100MM PAVEMENT QUALITY CONCRETE = 20 0MM

3. 1 .SITE CLEANING AND EXCAVATION Site Cleaning : Site clearing is the first step in any construction project that involves removing any elements on the land that may get in the way of the construction process.this includes shurbs,vegetation, rocks and other debris.The goal of site clearing is to create a construction site conducive to the project,allowing the construction team to start working on the actual structure.

4. EXCAVATION : Excavating is imp for removing large materials and obstacles from the site like boulders,trees,stumps and other types of debris, Excavators are also used to dig holes, pile dirt around the site of slope the land to meet the needs of the road .

5. 2 .LEVELING Levelling is an essential surveying technique used in various fields such as construction, engineering, architecture, and land surveying. In construction, levelling establishes the correct height and alignment of buildings, roads, and other infrastructure.

6. 3. MURRUM STOCK AND MURRUM SPREADING Fill the murrum in 150mm thick layers and compact it for the desired density by simultaneously watering it. This process of filling the murum in layers with watering shall be carried out till the desired reduced level is obtained. Every layer of murum shall be watered and compacted at optimum moisture content (O.M.C.)

7. 4. Water compaction When compacting aggregates the optimum water content in road materials is where the inner capillary layer changes to the outer capillary layer. Capillary forces are also very important factors in the frost heave process on roads.

8. Following progress has done during this periods:- 1.GSB COLLECTION ON SITE 2.SPRADING ON GSB SITE 3.GSB THICKNESS CHECKING 4.WATERING COMPACTION

10. 1.GSB COLLECTION ON SITE The full form of GSB is Granular-sub-base. It is the main layer that bears the load of the pavement or road. GS is commonly used in the construction sector. GSB plays the pivotal role in maintaining  the longevity, durability and stability of the roads and pavements.

11. 2. SPRADING ON GSB SITE l The GSB Material is spread with the help of motor grader on the approved layer of Sub-grade in single layer of 200 mm with Grading either IV or V. During spreading and mixing by grader in site, water is sprinkled over the material by water browser mounted on water tanker.

12. 3.GSB THICKNESS CHECKING

13. 4.WATERING COMPACTION  If the thickness of the compacted layer does not exceed 100mm,heavy weight hammer weight may be used. In case of large thickness laying shall be carried out for thickness of 175 mm compacted to 150 mm using surface vibratos to achive the required compaction.

15. LAYING OF PCC Plain cement concrete (PCC) is a mixture of cement, coarse aggregate, fine aggregate, and water. It's commonly used in road construction for its durability and strength. PCC provides a stable base for roads, withstands heavy loads, and resists weathering. The mix design and proportions depend on factors like traffic volume, climate, and soil conditions. Proper curing is essential for PCC to achieve its maximum strength and longevity .

16. LAYING OF PQC PQC stands for Pavement Quality Concrete, which is a type of concrete used in road construction for the top layer of the pavement. PQC offers higher strength, durability, and smoothness compared to plain cement concrete (PCC). It consists of a carefully designed mix of cement, aggregates, water, and sometimes additives or admixtures. PQC is typically laid in thinner layers than PCC, resulting in smoother road surfaces. It undergoes stringent quality control measures during mixing, placing, and curing to ensure uniformity and high performance. Properly constructed PQC contributes to long-lasting, low-maintenance roads.
