REPAIRING AND SURFACING OF EXISTING BITUMINOUS ROAD FROM JHARGORIA

Clearing & Grubbing Road Land Clearing and grubbing road land including uprooting rank vegetation, grass, bushes, shrubs, saplings and trees girth up to 300 mm, removal of stumps of trees cut earlier and disposal of unserviceable materials and stacking of serviceable material to be used or auctioned, up to a lead of 1000 metres including removal and disposal of top organic soil not exceeding 150 mm in thickness. II) By Mechanical Means A) In area of light jungle

Restoration of Rain Cuts Restoration of rain cuts with soil, moorum, gravel or a mixture of these, clearing the loose soil, benching for 300 mm width andextending continuously for asufficient length and height of benches shall be in the range of 150- 300mm. Fresh material shall be deposited in layers not exceeding 250 mm and compacting with plate compactor or power rammers or by suitable implements handled manually to restore the original alignment, levels and slopes as per the requiremnt of MORT&H's specification 3002

Maintenance of Earth Shoulder (stripping excess soil) Stripping excess soil from the shoulder surface to achieve the approved level and compacting with plate compactor as per the requirement of MORT&H's specification 3003. Note: The earth stripped from earthen shoulders to be dumped on the side slopes locally for disposal.

Scarifying Existing Bituminous Surface to a depth of 50 mm by Mechanical Means Scarifying the existing bituminous road surface to a depth of 50 mm and disposal of scarified material within all lifts and lead upto 1000 metres (Reference to MoRT&H's specification clause 305.4.3).

Construction of Shoulder Construction of Sub Base using Local Materials, spreading in uniform layers with Motor grader on prepared surface, including screening the metal as necessary, mixing by mix in place method with Rotavator at OMC, and compacting with vibratory roller to achieve the desired density, lighting, guarding and barricading including cost and carriage of all materials and making necessary earthen bundh of one metre wide on each side to protect the edges complete as per Clause 401 of Specifications for Road & Bridge Works of MoRT&H (5th Revision). For Construction of Sub Base by compacting 1st class brick aggregates (40 mm down) and sand (in proportion of 60:40). Add cost at site of 0.90 m3 of brick aggregates and 0.48 m3 of medium sand (loose volume) to arrive at the consolidated rate. Hard Shoulder with Jhama Khoa (40-63)mm

Providing, laying, spreading and compacting stone aggregates of specific sizes to water bound macadam specification including spreading in uniform thickness, hand packing, rolling with 3 wheeled steel/ vibratory roller 8-10 tonnes in stages to proper grade and camber, applying and brooming requisite type of screening/ binding Materials to fill up the interstices of coarse aggregate, watering and compacting to the required density (Reference to MoRT&H's specification 404). A) By Manual Means Grading- 1 (Table 400-9) Using Screening (Table 400-10) Type-B (11.2 mm aggregate)

Providing, laying, spreading and compacting stone aggregates of specific sizes to water bound macadam specification including spreading in uniform thickness, hand packing, rolling with 3 wheeled steel/ vibratory roller 8-10 tonnes in stages to proper grade and camber, applying and brooming requisite type of screening/ binding Materials to fill up the interstices of coarse aggregate, watering and compacting to the required density (Reference to MoRT&H's specification 404). A) By Manual Means Grading- 2 (Table 400-9) Using Screening (Table 400-10) Type-B (11.2 mm aggregate)

PRIMER COAT Providing and applying primer coat with cationic bitumen emulsion SS1 grade conforming to IS:8887 on prepared porous granular surface including clearing of road surface and spraying primer using mechanical means (Reference to MORT&H's specification clause 502). On WMM/WBM surface @ 0.70-1.0 kg /sqm For WBM/WMM Surface: with primer

TACK COAT Providing and applying tack coat with Cationic bitumen emulsion (RS1) complying with IS:8887 using emulsion pressure distributor on the prepared bituminous/granular /cement concrete pavement surface cleaned with mechanical broom and high pressure air jet (Reference to MORT&H's specification clause 503). ii) On Granular surface treated with primer @ 0.25 kg-0.30 kg /sqm.

TACK COAT Providing and applying tack coat with Cationic bitumen emulsion (RS1) complying with IS:8887 using emulsion pressure distributor on the prepared bituminous/granular /cement concrete pavement surface cleaned with mechanical broom and high pressure air jet (Reference to MORT&H's specification clause 503). i) On Bitumious surface@ 0.20 kg-0.30 kg /sqm.
