Govt. of Rajasthan has announced development of 20,000 Kms highways during next 5 years. Projects and schemes are being identified for implementation. This is the 8th (KD8) of 9 required deliverables, earlier 7 reports – Inception Report, Supplementary Inception Report, Report on Alignment and First Traffic Survey, Report on Land Plan Schedule and Utility Relocation, Report on Indicative GAD of Structures, Report on Environment, Social Impact Assessment and Draft Feasibility Report have been submitted. E-2 DESCRIPTION OF PROJECT ROAD E-2.1 General Project Road starts from Beawarat junction of NH-8 (km stone 58+187), (km stone 3+180 of SH-39) and ends km stone 45+322 of SH-39atBijaynagar (nearGulabpura) on NH-79 Junction in Ajmer District in the state of Rajasthan. The Project Road passes through important Villages/towns like Bayla, ShivpuraGhata, Ratanpura, Badka, Badiya, Ramgarh, Hanutiya, Berukheda, Sootikhera, Asan and ends at NH-79. The Total length of this road is 42.3 kms.

E-2.3 Right of Way The width of existing right of way (ROW) varies from 8m to 24m.The development along the road has been uncontrolled. Therefore, at certain locations encroachment within ROW has been observed in the form of shops, hotels, Dhabas and various other commercial establishments. E-2.4 Existing Alignment The existing roadgeometry by large satisfies thecodal requirements of IndianRoads Congress. There are few sharp curves which needto be re-designed for 80/100 KMPH.The alignment has been studied, based on physical features and other Constraints at site viz. Land acquisition, utilities, construction activities, presence of religious structures etc.It has been observed that BSNL Optical Fibre Cable (O.F.C.) is running along the road alignment. Indian Oil Corporation Limited’s (IOCL’s) Petroleum Line also crosses the Project Road at one location at Ex. Ch. Km 3+600. E-2.5 Existing Carriageway Intermediate lane &single lane carriageway with 0.5m to 2.0m earthen shoulder exists at various sections of the project road. Sl. No. Description Length (Km) 1 3.8m wide carriageway with 1.5m Earthen shoulder 0.500 2 5.5m wide carriageway with 1.5m to 2.0m Earthen shoulder 13.300 3 7.0m wide carriageway with 1.5m to 2.0m Earthen shoulder 28.500 Total 42.300 E-2.6 Existing Pavement Pavement Composition: The existing pavement consists of bituminous layers, WBM and granular sub base. The minimum existing thickness excluding sub grade is about 50mm BT- 200mm (WMM/WBM). Entire length of the road has bituminous surface except (built up sections). 15% of project road length is in good condition,67% in fair condition and 18 % in poor condition. E-2.7 Settlements The Project Road passes through important Villages/towns like Bayla, ShivpuraGhata, Ratanpura, Badka-Badiya, Ramgarh, Hanutiya, Bherukheda, Sootikhera and Asan. E-2.8 Culverts There are 27 slab culverts, 6 to be retained, 3 to be widened and 18 to be reconstructed. Out of 44 pipe culverts, 17 to be retained, 5 to be widened, and 22 are to be reconstructed.

All the scuppers are in fair condition so they are proposed for retained. E-2.9 Bridges There is no major bridge in the entire stretch of the project Highway. Four numbers of minor bridges exist on the Project Road at the following locations: 1) In Km 07 at existing chainage 6.300 2) In Km 14 at existingchainage 13.800 3) In Km 29 at existingchainage 28.130 4) In Km 37 at existing chainage 36.521 E-2.10 Causeways One causeway with 9m lengthexistsat Km12+027. Proposal for replacement with Twin cell Box culvert (2x3x2m) is made in “Improvements proposals”. E-2.11 Flyovers/Underpasses No RUB, ROB and at-grade railway level crossing exists on the Project Highway. E-2.12 Bypasses There are no congested villages/Towns in Project Highway which may require construction of Bypass as sufficient ROW is available. E-3 SURVEY AND INVESTIGATION E-3.1 Topographic Survey Detailed Topographical Survey to generate Digital Terrain Model of the defined Project Highway has been done. Main control points by DGPS,Subsidiary control points by Total Station and height control by Digital Level are established. E-3.2 Soil, Pavement Investigation In field investigation for existing sub-grade, test pits of size 1.0 m x 1.0 m were excavated up to the sub-grade level. The general observations noted during the field investigation at each test pit are reported below. Details of pavement composition Visual identification of sub-grade soil Field dry density (FDD) of the sub-grade with Core cutter method Field moisture content (FMC) FDD & FMC The FDD and FMC values vary from 1.76 to 1.84 g/cc and 4.1 to 6.6 % respectively. Laboratory Tests on Existing Sub-grade (Main Carriageway) The following laboratory tests were carried out on the disturbed soil samples of test pits.

The CBR varies from 12.5 % to 14.4 %. Existing Pavement Composition The existing pavement crust consists of bituminous layers, granular layers and sub-grade soil. Total thickness of the flexible section of the pavement varies from 180mm to 300mm. The thickness of bituminous surface varies from 20mm to 100mm. Pavement Deflection and sub grade strength: The BBD values vary between 1.560 mm to 2.474mm deflection along the Project Highway. E-4 TRAFFIC ANALYSIS The primary traffic surveys were conducted in November 2014, April and May 2015. The data collected have been analysed. The ADT, AADT, tollable and non-tollable traffic was calculated.
