SECTION 1600 217 Quality Assurance Handbook for Rural Roads HILL ROAD CONSTRUCTION
1600 : HILL ROAD CONSTRUCTION 219 Quality Assurance Handbook for Rural Roads Most of the quality aspects related to site clearance, setting out of the works, earthworks, including rock cutting and blasting operations; construction of subgrade, subbase, base, bituminous surfacing; construction of drainage and cross-drainage works; protection measures and retaining structures; stone masonry, brick masonry and cement concrete are already covered under the respective sections of this Book. The methodology and quality requirements and quality tests specified therein are relevant to hill road construction as well and may be followed. The Specifications already covered under various sections are not repeated in this Section. This Section therefore, brings out only those of the construction aspects and related quality requirements for hill roads which have not been covered in previous sections. Hill Road Construction should be taken up after carrying out necessary Geo-technical investigations. A. Methodology 1. Site Clearances Carry out the site clearance to the requirements of Section 200. 2. Setting Out Set out the work carefully with reference to the Reference pillars fixed at the Project preparation stage. For details refer to Sub-section 108. (i) Mark the hill side edge of roadway (back-cutting line) on the hill face accounting for the specified slope of hill cutting. Ensure its accuracy by measuring distance from each reference peg so as to match with the drawing. (ii) Where the road is in filling, ensure that the outside edge of the retaining wall is accurately fixed as measured from the Reference Pillar. (iii) Ensure that the roadway demarcation lines between consecutive reference pillars follow the curvature shown on the drawings. (iv) In case any discrepancy in length (measured parallel to road grade), direction and grade is found between two reference pillars beyond the specified tolerances, review and take corrective measures. (v) Ensure that the level pillars are fixed as per the final longitudinal gradient. 3. Rock Cutting (i) Carry out rock cutting to the specified lines, grades, side slopes, width and cross-slope conforming to the drawings. (ii) Ensure that hill cutting is carried out in a manner to minimize the deforestation to the extent possible, following the Environmental Management Plan (EMP). Necessary mitigation measures shall be ensured before start of hill cutting work. (iii) Take care to restrict the rock cutting to the required width. For steep slopes (say more than 30 degrees depending upon the type of rock) initial 3 m bends may be cut manually for movement of machinery.
