|Abstract:||The use of liinc4ly ash t'g re ato iixthro for road eonotzuctiOfl as base course In receiving, considerable popularitV these d s. Lime and fly ash which have 'het used In this lnmatigation have bec obtoftid txori local source end ' (` Power Station, flci Delhi, respective y. The concept of repeated loading appears to be more realistic and aiiulto the pavement behaviour more closely than the static loading„ Beat cpoefteno used to evaluate the fatigue behaviour of li e-fly asb1.tggregatc rniXt1iXc were tented in flexure up to failure by repeated loadings. The raanit* do of the load which was hold constant for each test epcciren and the nuw bor of cy ales of repeated loading required to fracture each spoeiren were measured. .ezurol tensile strain under repeated loading test of each bean waC_ also measured, IL plot botwoat logarithm of fatigue life and Initial floural strains boars linear relationship, Recording of strain history of each beam ahoucd that Initial strain during repeated loam, r ncd constant upto a certain limit of repetitions beyond which it suddenly raised eansing collapo of beam cpocimci, Failure strains are found to be in the range of 190 to 210 miexo units indicating Significant rigidity of the r citerial RepetItions causing initial damage have bec found to boor a linear correlatIon with repetition ueusing failure on, lag J.og axes.
