All road markings shall be maintained so as to be clearly visible to the driver. An yearly schedule of re-painting the markings should be maintained to ensure proper maintenance of the markings. 2. The material for maintenance of road markings shall be in conformity with subsection 1702. 3. Repainting and lettering on kilometre and 200-m stones shall be as per guidelines indicated in IRC:8 & IRC:26.

Plantation, weeds, shrubbery and mud etc. shall not be allowed to obscure the stones/signs. 5. Iron, wooden or concrete posts for road delineators shall be repainted regularly, especially after the rains to keep them clean and visible. The ground around the delineators, hazard markers, roadway indicators and object markers should be kept clean by cutting grass/weeds and bushes etc. periodically to maintain the visibility of the delineators. 6. The material for repair/replacement of road delineators, hazard markers, roadway indicators and object markers shall conform to the guidelines included in IRC:79. 7. All branches of trees extending above the roadway shall be cut or trimmed so as to provide a clear height of 5 m above the road surface and shoulders. 8. All shrubs, grass and weeds in the roadway land shall be trimmed and debris removed to a suitable location as directed by Engineer to ensure unobstructed sight distance of adequate length. 9.

1. General 243 Quality Assurance Handbook for Rural Roads 1.1. As part of an overall Quality Management System, the aspect of ‘Quality Control’ is to be treated as distinctly different from ‘Quality Monitoring’, both at the State and Central levels. The aspect of Quality Control of Works has been dealt with in detail in Chapter 3 of this Hand Book. This Chapter deals with Quality Monitoring which essentially involves only expeditious random checking by specially appointed Quality Monitors both at the State and Central levels to ensure that the works are indeed being carried out as per the prescribed standards. 1.2. In the three-tier system of Quality Management being adopted for rural roads constructed under the Pradhan Mantri Gram Sadak Yojana (PMGSY), while the first tier is an in-house quality control by the executing agency, the second tier is an independent quality check and monitoring by Statelevel Quality Monitors (SQMs) operationalized by the State. In the third tier of quality management, the National Rural Roads Development Agency (NRRDA) arranges for Quality Monitoring through independent monitors, termed as National Quality Monitors (NQMs). The main objective of quality monitoring at the second and third tiers is to verify whether the quality of road works executed by the States under the PMGSY conforms to the specified standards and to see if the system of quality management in the State is indeed effective. 2. Role of The Quality Monitors 2.1. The role of the quality monitors is more of providing guidance to the State implementation authority than to pinpoint specific faults. Accordingly, the Quality Monitors are required to bring out the weaknesses or shortcomings in the quality control system being adopted by the State and to provide a feed back for improvement. This role can be fulfilled by the field inspections of the PMGSY works by Quality Monitors during different stages of construction and also through inspection of completed works. 2.2. It may be pointed out here that at the State level, there has to be a more rigorous and involved role of State Quality Monitors requiring more frequent visits of SQMs compared to the National-level Quality Monitors. 3. Field Inspections by Quality Monitors CHAPTER 4 QUALITY MONITORING 3.1. The field inspections by Quality Monitors need to be so organised that every Quality Monitor is able to inspect the rural road works during different stages of construction like Setting Out, Earthwork, Subgrade, Sub-base, Base, Surfacing and Drainage system, including culverts and bridges, besides completed works. Since the duration of such field inspections will be short, the Quality Monitors will have to depend largely on visual inspection, simple hand-feel tests, use of simple gadgets like Camber Board and Straight Edges etc. available in the Field Laboratory.
