501 extractive question-and-answer pairs built from Slide 1, published by crridom.gov.in. Every answer is a verbatim span of text the source prints, and each row carries the passage it sits in, its offset in that passage, the source quote, the page and the location in the document, so any row can be checked against the original. 238 of the 501 pairs (47.5%) are explanatory questions and 263 restate a figure. 98.00% of rows pass the corpus quality gate.

| What process uses geological structural data to determine modes of failure? | carried out with the help of geological structural data to find out mode of failures | Gneissic structures are well developed showing alternate dark and light colored mineral layers. Stereographic analysis was carried out with the help of geological structural data to find out mode of failures. It was found that plane wedge and rock fall conditions are prevailing in the field. | 123 | definition | 1.000 | Stereographic analysis was carried out with the help of geological structural data to find out mode of failures. | 18 | page=18,block=0 | 0.850 | valid |
| What type of solution is Roadzyme soil stabiliser? | an enzyme based dark brown liquid solution | This project was entrusted to CSIR-CRRI for evaluating the suitability of Roadzyme liquid as a soil stabiliser in the presence of cement by detailed laboratory investigations. Roadzyme soil stabiliser is an enzyme based dark brown liquid solution. Local silty soil was from Delhi blended with cement in the range of 3 to 9% and these stabilized mixes were stabilized with Roadzyme stabilizer content in the range of 0.002 to 0.01%. | 204 | definition | 1.000 | Roadzyme soil stabiliser is an enzyme based dark brown liquid solution. | 26 | page=26,block=0 | 0.850 | valid |
| What was the stabilised red mud sample evaluated for? | characterised for application in different pavement layers | It was blended with fly ash in the range of 25 - 75 % (mechanical stabilisation) and with cement in the range of 3 - 9 % (chemical stabilisation). Stabilised red mud sample was characterised for application in different pavement layers. From preliminary investigation, it was observed that red mud is a silt size material and can be used in the construction of embankment. | 177 | definition | 1.000 | Stabilised red mud sample was characterised for application in different pavement layers. | 31 | page=31,block=0 | 0.850 | valid |
| What was the purpose of the laboratory investigation involving phosphogypsum? | carried out to examine the feasibility of phosphogypsum waste material in the construction of embankment, sub grade and granular sub base layers | Phosphogypsum is a waste material generated as a by-product during manufacturing of phosphoric acid. Laboratory investigation was carried out to examine the feasibility of phosphogypsum waste material in the construction of embankment, sub grade and granular sub base layers. After that, an experimental test road was constructed using phosphogypsum at Paradeep, Orissa (pilot project). | 130 | definition | 1.000 | Laboratory investigation was carried out to examine the feasibility of phosphogypsum waste material in the construction of embankment, sub grade and granular sub base layers. | 31 | page=31,block=0 | 0.850 | valid |
| What is the design life and traffic capacity of the pavement? | designed for 20 year design life with 100 MSA design traffic | Axle load survey is carried out to determine the VDF of commercial vehicles plying on the project road Axle load survey reveals that the road section is majorly occupied by the heavy commercial traffic comprising tandem, tridem and multi axle trucks with varying VDF of 7 to 20. Pavement is designed for 20 year design life with 100 MSA design traffic. Based on the mechanistic properties of steel slag mixes and mechanistic analysis, overall pavement thickness of steel slag pavement section is reduced by 32 % in comparison to the pavement thickness determined as per IRC: 37:2018 for control section built through natural aggregate. | 291 | definition | 1.000 | Pavement is designed for 20 year design life with 100 MSA design traffic. | 40 | page=40,block=0 | 0.850 | valid |

| What is the purpose of the proposed research related to Traffic Engineering and Safety? | intended to help Traffic Engineering and Safety Research & Development 45 CSIR-CRRI Annuarl Report 2020-21 drivers to improve road safety | Loss of efficiency of the driver to drive a vehicle due to prolonged driving, sleep deprivation, exhaustion is known as driver fatigue. The proposed research is intended to help Traffic Engineering and Safety Research & Development 45 CSIR-CRRI Annuarl Report 2020-21 drivers to improve road safety. More specifically, this research will experimentally (1) study driver fatigue and its influence on driving performance, and (2) try to develop nomograph which will tell the driver which fatigue state he/she is in based on their behavior and duration of driving and what countermeasures they should take to avoid possible accident. | 161 | definition | 1.000 | The proposed research is intended to help Traffic Engineering and Safety Research & Development 45 CSIR-CRRI Annuarl Report 2020-21 drivers to improve road safety. | 58 | page=58,block=1 | 0.850 | valid |
| What is missing for testing the effects of various policy measures on urban areas? | no a standardized assessment framework model or software to test various policy measures effects on urban areas | Current methods mentioned in literature are complex in nature. Currently there is no a standardized assessment framework model or software to test various policy measures effects on urban areas. Further, every application is site dependent and uses specific set of indicators. | 82 | definition | 1.000 | Currently there is no a standardized assessment framework model or software to test various policy measures effects on urban areas. | 70 | page=70,block=0 | 0.850 | valid |
| What is red mud, and how is it generated? | Red mud is an industrial waste material generated as a by-product during extraction of aluminium from its bauxite ore. | Utilization of Red mud for Road and Structural fill applications Sponsoring Agency: Hindalco Industries Mumbai Duration of the project : March 2021 to August 2023 Broad Objectives: (a) Geotechnical characterization of Red mud waste material with or without mechanical and chemical characterisation for application in road construction. (b) Redmud as a structural fill material (Structures over Red mud fills/Road over Red mud fills) Red mud is an industrial waste material generated as a by-product during extraction of aluminium from its bauxite ore. Characterization (physical, chemical and geotechnical) of red mud has been carried out for application in road and as a structural fill after collection of sample from M/s Hindalco Industries, Orissa. It was blended with fly ash in the range of 25 - 75 % (mechanical stabilisation) and with cement in the range of 3 - 9 % (chemical stabilisation). | 433 | definition | 1.000 | (b) Redmud as a structural fill material (Structures over Red mud fills/Road over Red mud fills) Red mud is an industrial waste material generated as a by-product during extraction of aluminium from its bauxite ore.
