TABLE 508.1.4: QUALITY CONTROL TESTS DURING CONSTRUCTION Type of Test Frequency 1. Grading of Aggregates (IS:2386 Part 1) At least two tests per day 2. Binder Content before seal coat At least two tests per day 3. Temperature of Binder Regular close intervals 4. Thickness of layer Regularly at close intervals 5. Aggregate impact value (IS:2386-Part 4) At random one test per km 5.3 Quality Control Checks by AE/EE The quality checks to be exercised by AE/EE are indicated in Table 508.1.5. TABLE 508.1.5: QUALITY CONTROL CHECKS BY AE/EE Stage Test Frequency Designation of Inspecting Officer 1. Finished Pre Mix (i) Binder Content before providing seal One test for every 500 m AE Carpet Surfacing coat length of the layer (ii) Visual inspection of finished surface Full length EE (iii) Surface Regularity and Random Checking AE Transverse profile 104
C. Do’s and Don’ts Do’s Don’ts 1. Ensure that aggregates for premix carpet and seal coat conform to the prescribed physical and grading requirements and are clean and dry. 2. Exercise strict control over mixing and laying temperature as per specifications using appropriate thermometers. 3. Rolling operations should be completed before the temperature of the mix falls below 100oC. 508.2 PREMIX CARPET USING BITUMEN EMULSION A. Methodology 105 Quality Assurance Handbook for Rural Roads 1. Do not allow manual mixing. 2. Do not undertake the work in foggy, rainy or windy weather or when the atmospheric temperature in the shade is less than 10oC or when the surface is wet. 3. Do not allow the premix material to adhere to the roller wheels. Do not use excess water for the purpose. Light sprinkling should do. 4. Do not allow the roller to stand on newly laid material. 5. Do not allow any traffic without laying seal coat over the premix carpet. 1. Prepare the base on which premix carpet is to be laid to the specified lines, grade and cross section 2. Apply a tack coat over an existing prepared black top surface. 3. The quantities of material required for 20 mm thick premix carpet should be as indicated below (i) Aggregate as per Table 508.1.1 of Sub-section 508.1 (ii) Binder : Cationic Bitumen Emulsion (a) For 0.18 m3 of 13.2 mm nominal size stone at 78 kg 14.0 kg cationic bitumen emulsion per m3 (b) For 0.09 m3 of 11.2 mm nominal size stone at 84 kg 7.5 kg cationic bitumen emulsion per m3 Total 21.5 kg 4. Premix bitumen emulsion and aggregates in a suitable mixture such as cold mixing plant as per IS:5435 (revised) or concrete mixture 5. Spread the premix to the desired thickness, grade, cross fall within 10 minutes of applying the tack coat and ensure that all levelling, raking is completed within 20 minutes of the mixing. 6. Roll the surface as per Para 6 & 7 of the methodology described in Sub-section 508.1 7. Provide a seal coat as specified in the contract within 4-6 hours after laying the premix carpet. Follow Sub-section 510 for the work on seal coat. 8. Preferably, the road should be opened to traffic after 24 hours of laying the seal coat. In single lane roads traffic may ordinarily be allowed after 6-8 hours with the care that the speed is rigorously restricted to not more than 16 km/h.
