(It.no.2.2-II-A)

Excavation for roadway in soil by mechanical means including cutting and pushing the earth to site of embankment upto a distance of 100 m, including trimming bottom and side slopes in accordance with requirements of lines, grades and cross-sections. (It.no.3.5-II)

Scarifying the existing bituminous road surface to a depth of 150 mm and disposal of scarified material with a lift upto 3 m and lead upto 1000 m as per Technical Specification Clause 301.4. (It.No.3.2)

Construction of subgrade and earthen shoulders with approved material obtained from borrow pits with all lifts and leads, transporting to site, spreading, grading to required slope and compacted to meet requirement of Table 300.2 with lead upto 1000 m as per Technical Specification Clause 303.1.(It.No.3.14)

Providing pulverizing, spreading, milling and mixing of chemical additives at the appropriate rate as per job mix design in accordance with IRC-72-2015 and IRC-37-2012. Cementations additive @ rate as per design mix should be spread evenly on the existing pavement/sub grade manually. The in-situ stabilization process shall be carried out by a mobile and self propelled stabilizer / reclaimer with minimum engine horse power of 440 kw with a variable working depth up to 50 cm. The resultant stabilized mix then would be profiled to the required grade, level and thickness using motor grader and the mix would be compacted using 20 tone pad foot roller in combination with smooth wheel roller to achieve desired proctor density as per IRC 37-2012 and complete in all respect and curing with water as required including all materials, labour and machinery etc. The entire in-situ process would be carried out in single pass with milling and pulverising of damaged asphalt pavement / soil/ aggregates / soil-aggregate mixture to the desired depth and with simultaneous addition of additives and water with machine integrated spray bars fitted on the wheeled self-propelled and vibratory pad foot roller to achieve the desired proctor density in all respects. The final stabilized layer should meet inter alia provision given IRC 72-2015, IRC 37-2012 & 2018, IRC SP 89 Pt. II 2018, and other relevant codes, the following specification: Axial Static Modulus of Elasticity (E) min 5000 Mpa, 28 days, Axial Unconfined Compressive Strength min 4.5/7 Mpa in 7/28 days, GeoGauge Modulus (MG) (field measurement) Min 180 Mpa 0 to 3 days, Normalized Deflection Max 0.25 mm, Flexure strength min 1.5 Mpa, Aggregate requirement Nil/minimum/as per JMF, Durability % loss < 5 % after 12 cycle and CBR > 100 %
