112 India Infrastructure Report 2007 Box 5.1 The Concept and Utility of Core Network The DRRP is a compendium of the existing and proposed road network system in the district which clearly identifies the proposed roads for connecting the yet unconnected habitations to already connected habitations or all-weather roads, in an economically efficient way. While selecting the connectivity to the unconnected habitation by single all weather road, optimization principle is applied through Utility Value and Road Index for linkage of the selected habitation with an already connected habitation. The Core Network (CN) is a subset of DRRP and represents the minimum network that ensures connectivity to all the eligible habitations through single all weather roads. This enables continuity with the nearest market centre (either existing or a potential one). This network is the minimum network that is to be kept in good condition. It consists of identified link routes and through routes. Link Route: Link Routes are the roads connecting a single habitation or a group of habitations to through routes or district roads leading to market centres. Through Route: Through routes are the roads which collect traffic from several link roads or a long chain of habitations and lead it to marketing centres either directly or through the higher category of roads.

As such, cost of construction under PMGSY varies investigated in detail. Currently, cost varies from Rs 15–16widely across states and even within a state and across districts. lakh per unit length to as high as Rs 45–50 lakh per unitCost of construction also depends on the choice of technology length in different states (Table A5.6). Probable reasons forused and labour–machine mix. cost variation include topography of the local area, distance In a labour-surplus economy like India, it is, therefore, from the availability of construction material, earthworknot only necessary to design the rural roads on the basis of required and so on (Box 5.2). Box 5.2 Why Cost varies across Regions A typical rural road consists of compacted sub-grade, granular sub-base, base-course with graded aggregate and thin bituminous surface course in the form of pre-mix concrete with a seal coat. In order to ensure the serviceability of the road through out the year with safety, necessary cross drainage (CD) structures, side drains, road signs, and other road furniture should be an integral part of the rural road. The detailed analysis of cost variation of rural roads was carried out at IIT, Roorkee covering 480 roads in 50 districts of Bihar, Uttaranchal, and Uttar Pradesh. The analysis decomposed the cost of construction into cost towards site clearance, retaining walls, CD structures, earthwork, sub-base, base-course, and surface course. The average cost of different components per km of the sample analysed is presented in the table below.

Total cost of construction is 33 per cent higher in hill areas than in plain areas. 2. On an average, the number of cross drainage structures required per km of road in plain area is 3, whereas in the hilly region this requirement is 8. This explains the higher cost of CD works in Uttaranchal (Rs 6.3 lakh) as compared to the cost of these works in Bihar and Uttar Pradesh (Rs 1.05 lakh and Rs 1.35 lakh respectively) 3. The cost of site clearance is a significant component of the total cost in hilly areas (Rs 2.47 lakh in Uttaranchal), whereas it is negligible in plain areas (Rs 4000–6000 per km in Bihar and Uttar Pradesh). 4. The haulage cost for bringing construction material is more in the state of Bihar (Rs 7.61 lakh) followed by Uttar Pradesh (Rs 6.02 lakh) compared to Uttaranchal (Rs 4.76 lakh). This explains higher cost of construction in Bihar as compared to Uttar Pradesh even though the regional and climatic conditions are similar. The analysis also revealed that even within a state, cost variation can be significant across the districts owing to the site specific conditions. The findings of the study warrant greater attention to detailed site investigations and technology option study at the time of preparing of DPR.

Further,
120 India Infrastructure Report 2007 Box 5.3 Use of locally available materials Anil Kumar Sagar FLY ASH FOR ROAD CONSTRUCTION WORKS Coal is the most easily available fuel for power generation in India. Huge quantities of fly ash are produced as waste by-product of coal combustion. The present annual generation of fly ash is estimated to be about 140 million tonnes. The physical and chemical properties of fly ash depend upon the type of coal, its grinding and combustion techniques, collection, and disposal systems. Fly ash reacts with lime in presence of moisture to form cementitious compounds. This is known as pozzolanic activity. The pozzolanic property of fly ash enables it to be used as an alternate binder in place of cement. While coarser fly ash can be used as fill material, the finer ash can be used for replacement of sand and cement in road construction works. Use of fly ash for rural road work has been covered in IRC:SP:20 2002 and Rural Road Manual (MoRD, 2004b and Vittal, 2000). Sub-base course can be constructed using pond ash or bottom ash replacing conventionally used moorum. Laboratory and field studies conducted in India and abroad have established that fly ash can be adopted for stabilization of sub-base/base. Fly ashes are cohesionless materials, and therefore non-plastic in nature while soil particles are generally cohesive. Mixing of soil and ash in suitable proportions improves the gradation and plasticity characteristics of the mix, thereby improving the strength. Addition of small amounts of lime greatly improves the strength characteristics of fly ash stabilized layers. 3 to 5 per cent of lime is used depending upon the quality of lime. The use of stabilized fly ash sub-base/base courses would be particularly attractive in locations where fly ash is easily available and supply of aggregate is expensive. The proportion 1:2:9 of lime, fly ash and moorum or sand has been found to provide the best performance. Fly ash can be utilized for constructing semi-rigid pavements in the form of lime-fly ash concrete, dry lean fly ash concrete. Pavements constructed using these mixes possess higher flexural strength than flexible pavements and hence they are classified as semi- rigid pavements. Fly ash can be used for construction of rigid pavements also by using cement-fly ash concrete, high performance concrete, roller compacted concrete and so on. Fly ash can be used in place of soil to construct road embankments. Typically in developed urban and industrial areas, natural borrow sources are scarce, and as a result borrow soil is very expensive. Environmental degradation caused due to use of top soil for embankment construction is also very high. Fly ash can provide an economical and suitable alternative material to earth for construction of embankments. Coal ash can be used for construction of embankments of rural road projects near thermal power plants. The notification issued by Ministry of Environment and Forests, Government of India dated August 27, 2003 has made usage of coal ash compulsory in all projects being undertaken within 100 km radius of the thermal power plant. The notification states that, ‘No agency, person or organisation shall, within a radius of 100 km of a thermal power plant undertake construction or approve design for construction of roads or flyover embankments in contravention of the guidelines/specifications issued by the Indian Road Congress (IRC) as contained in the specification No. SP:58 of 2001’ (Kumar et al. 2005). Various demonstration projects involving use of fly ash have been undertaken. One such project was the construction of Salarpur– Dadupur rural link road using fly ash. The project was taken up by the CRRI in collaboration with NTPC Ltd under the Canadian International Development Agency (CIDA) initiative. The site is situated at a distance of 5 km from National Capital Power Station (NCPS), Dadri in U.P. Salarpur and Dadupur villages are part of a same panchayat and have a combined population of about 2000 persons. The length of the Salarpur-Dadupur link road is about 1.4 km. In this project bottom ash was used as embankment fill material and fly ash collected in dry form was used for stabilization and as admixture in roller compacted concrete. The embankment was constructed using bottom ash as core material with soil cover of 30 cm thickness. Fly ash stabilized using cement (8 per cent cement and 92 per cent fly ash) was used for laying base course (compacted thickness of 10 cm). Fly ash and cement were mixed in a concrete mixer and water required to bring moisture content to Optimum Moisture Content (OMC) was added during mixing. The mix was manually laid to conform to grade and camber. Compaction was carried out using static roller. The stabilised layer was cured for seven days by sprinkling water at frequent intervals before placing the subsequent layer. A total quantity of about 5000 tonnes of ash was used for both fill and pavement works in this project. Keeping in view the fact that the link road is located in a remote area and only light traffic is expected to ply on the road, the pavement is providing satisfactory service. The construction work was taken up in March 2002 and completed in about 60 days. The total construction cost of the road was Rs 13.51 lakh. Since disposal of fly ash is a problem for thermal power plants, it has also been argued that fly ash be provided at a negative cost to the TPP. In such cases, fly ash is provided free of cost to the road manufacturer and the cost of transportation of fly ash to the site is borne by the thermal power plant. IRON AND STEEL SLAG FOR ROAD CONSTRUCTION Steel making is a strategic requirement of the economy of developing nation like India. Many steel plants have been set up in our country. However, production of iron and steel is associated with the generation of waste materials like slag. Normally, production of
Rural Roads 121one tonne of steel results in generation of one tonne of solid waste. Big steel plants in India generate about 29 million tonnes of wastematerial annually. In addition, there are several medium and small plants all over the country. Slag reduces the porosity and permeabilityof soil, thus increasing the water logging problem. It causes respiratory ailment among nearby residents, contaminates ground water,and adversely affects the landscape of the area. Slag can be used as pavement material in a variety of forms. It can be used as a base orsub-base material either in bound or unbound condition. It meets all the requirements set forth by the MoRTH. As per IRC:37–2001,Rs 5 lakh per km can be saved by using slag as road material (Kumar et al. 2002). It is evident that steel plant by-products, either as such or in suitable combination, can be used in sub-base or base course layer ofa road pavement. In order to compare the structural performance of these materials test sections were constructed using slags atRourkela in 1996–7. Post construction performance monitoring showed that the test sections are comparable to control sectionsconstructed using conventional materials.MARBLE DUSTWidely found in Rajasthan, it is a waste material of marble industry. It has been shown that the California Bearing Ratio (CBR) of thesub-soil may be increased by upto 40 per cent to 50 per cent by mixing 15 per cent to 25 per cent of marble dust depending upon thenature of soil. Thus the cost of construction may be reduced considerably.PHOSPHOGYPSUMIt is a by-product of phosphoric acid based fertilizer plants. It can be used to stabilize black cotton soils as it reduces the shrinkage and swellingof black cotton soil. The fertilizer plant of Indogulf Corporation located at Dalhej, Gujarat has demonstrated usage of this technology. Thecost of road after phosphogypsum stabilization is about 25 per cent less than the normal construction cost (Misra et al. 2004).MUNICIPAL WASTES IN ROAD CONSTRUCTIONIt is estimated that the average daily refuse generation in a metropolitan city like Delhi is approximately about 4000 tonnes. Disposalof this large quantity of wastes need careful planning. Presently, municipal corporations dispose these solid wastes mainly throughsanitary land fill method and composting. While organic wastes are used for composting to yield manure, inorganic wastes are difficultto dispose. Under the aegis of Ministry of Environment and Forests, a project was taken up at CRRI to use inorganic part of the processedwastes in road construction. A small length of the road in north Delhi was identified for construction as test section. Soil samples werecollected from subgrade and borrow areas to study their strength and geotechnical characteristics in order to design suitable pavementcross sections using inorganic part of the municipal wastes in appropriate layers of the proposed test section. The processed waste notbeing a suitable material in itself, additives like local soil, cement, lime, fly ash were used in different proportions in sub-base/basecourse construction. Pavement specifications were developed for construction of test section at the identified site. The constructionwork was completed satisfactorily in May 1996. Waste plastic has also been used in the construction of rural roads. A pilot road namely Saint Tirisulam road at Saint ThomasMount Panchayat Union in Kancheepuram district, Tamil Nadu was laid by the joint effort of Government of Tamil Nadu andGovernment of India. The technical support was provided by CRRI, IIT Chennai, and Theyagarajar College, Madurai. The road waslaid using waste plastic mixed bituminous mix. This road had better resistance to raveling and offered more resistance to stripping andformation of pot holes. The aggregates coated with plastics and binders presented better resistance to water.USE OF DHANDLA IN CENTRAL RAJASTHANDue to non-availability of hard stone within economical distances in desert areas, particularly in Central Rajasthan, road constructionhas been posing serious problems, especially in rural areas. It is a common observation in desert areas that on account of the non-cohesive nature of desert sand sub-grade, the sub-base material has the tendency to sink into the subgrade resulting in deformationsof various shapes and sizes. These deformations are subsequently reflected in the road surface causing either immobility or hamperingthe vehicular traffic. It is, therefore, considered an essential pre-requisite to provide adequate support to the pavement for betterperformance. This could be achieved either by stabilizing the desert sand sub grade with additives or by providing additionalthickness in the sub-base. Such treatments would result in increased cost of road construction. The Central and Western parts ofRajasthan have, at present, quite thin density of population where the rate of growth in the volume of traffic on rural roads is notexpected to rise at a fast rate in the near future. It is quite imperative, therefore, to utilize the locally available road materials to themaximum possible extent. A calcareous material locally known as ‘Dhandla’ is found in abundance under an overburden of 1.5 to 2.5 metres. Dhandla, beingquite soft, gets completely crushed under the road roller. It has been found that the bearing capacity of Dhandla was considerablyimproved when compacted manually and could be effectively used in the lower layer of low-volume roads. Test tracks have been laidusing Dhandla. It is seen that substantial economy can be achieved by using this low grade material for road construction.
122 India Infrastructure Report 2007 Box 5.4 Pilot Project on Application of Jute Geo-Textile in Rural Roads Jute Geo-Textile (JGT) is a natural technical textile laid in or on soil to improve its engineering properties. JGT is made out of yarn obtained from the jute plant. It has high moisture absorption capacity, excellent drapability, and high initial tensile strength. It is environment friendly, biodegradable, easily available, and economical. Use of JGT leads to natural consolidation of sub-grade soil and has a potential to enhance the CBR value of the sub-grade by 1.5 to 3 times. Use of JGT dates back to as early as in 1920s when it was tried in some sections of a road at Dundee in Scotland. It was also used in a major road in Calcutta by the British in 1934. The NRRDA has taken up a pilot project in collaboration with the Jute Manufacturers Development Council (JMDC) to demonstrate the potential benefits of the use of JGT in construction of rural roads. This pilot project aims at standardization of different types of JGT. Under the pilot project, ten roads have been selected in Assam, Chhattisgarh, Madhya Pradesh, and Orissa covering a length of 47.84 km (Table B5.4.1). Central Road Research Institute has been engaged as a technical consultant for this project for project preparation, quality control, monitoring, and performance evaluation.
