4. Quality Monitoring only in exceptional suspect cases that detailed laboratory tests may be necessary. The Quality Monitors need to bear in mind that all the checks made by them should be in accordance with the provisions made in the approved Plans and Bill of Quantities forming part of the Contract. 3.2. For purposes of Quality Monitoring, only random checks are envisaged. For soils and other road materials being used at site, a representative sample from the borrow pit in use or stockpiled material can be collected at random. Similarly, while checking placement moisture content during compaction, a random sample can be collected and its moisture content determined using a Rapid Moisture Meter. For insitu density determination by sand replacement method, the location of the test can be selected at random. A similar approach can be adopted during bituminous and cement concrete construction. However, where a completed section is to be checked, the entire completed section should be divided into 10 sub-sections, of equal length. Two such sub-sections may be selected at random for carrying out the needed tests. The longitudinal profile should be tested by a 3 m straight edge in a stretch of atleast 9 m length and the transverse profile at two or three locations at each 100 m length. 4. ITEMS TO BE CHECKED BY QUALITY MONITORS The various items to be checked by the Quality Monitors are given below, with respect to the MORD Specifications for Rural Roads. 1.
