Subject : 621.438 Aircraft Gas Turbine Engines
Keywords : Metal tracks ;During World War-II ;Pollit's account
Abstract : In this paper, the subject of metal tracks as means of rapid construction of runways during World War-II has been reviewed. Brief description of some of the important light and heavy metal tracks has been given. Merits and demerits of both types of track are stated. Factors responsible for successful functioning of the track are enumerated and Pollit's account of the theory of track is presented. A summary of the post-war research on the field scale as carried out in U.K. is incorporated. Present trends obtaining in U.S.A. are indicated along with concluding remarks. |
| | Scope of soil cement in runways construction in India

Source : Defence Science Journal ; Vol:10(2) ; 1960 ; pp 141-156
Subject : 624 Civil Engineering
Keywords : Soil-cement ;Heavy duty military
Abstract : The subject of soil-cement has been dealt with at some length. Developments in other countries in runway construction embodying soil-cement are reviewed and an account of Heavy Duty Military airport having soil-cement runway is furnished. Soils of India have been examined to determine their suitability for cement stabilisation. It is proposed that a percentage water stability of 80should be a good criterion of suitability of a given soil. Salient features of soil-cement construction are presented here and large scale field trials prior to adopting construction of soil-cement runways in the near future have been recommended. |
| | Aniline-Furfural as a Soil Stabiliser

Subject : 631.4 Soil Science;551.58 Climatology;551.5 Meteorology
Keywords : Soil Stabiliser ;Aniline-furfural
Abstract : A comparison has been made of aniline-furfural and cement as soil stabilisers with the Gangetic alluvial soil of Delhi. Three compositions of aniline-furfural and two of cement were employed. The 7 day unconfined compressive strength of soil stabilised with resin composition-5% aniline and 2.5% furfural is nearly equal to the strength of soil established with 20% cement. Treatment with aniline-furfural produces high strength of nearly 1 ton per sq. in. when the resin composition is 8% aniline and 4% furfural on soil weight basis. The reduction in strength of the aniline-furfural and cement stabilised soils on being subjected to successive wetting-drying and freezing-thawing cycles is almost the same for both the soils. Stabilisation of soils with aniline-furfural is better suited to cold climates |
| | Field Strength of Soils in Relation to Texture and Moisture Content

Subject : 624 Civil Engineering
Keywords : Clayey and Silty Soils ;Dry and Wet Seasons;Cone Index;In Situ
Abstract : Strength profiles of in situ soil representing different textual groups except silt have been established by measuring cone index values at the surface and thereafter successive depth intervals of 3 inch upto a maximum depth of 24 inches at 92 sites during dry and wet seasons. In wet state clayey and silty soils lose nearly half of their original strength. Most soil types show a progressive increase in strength with increase in depth in both dry and wet states. |
