Evaluation of Rutting Susceptibility of Bituminous Mixes Using Finite Element Modeling
Abstract: Pavement performance mainly depends on the quality of bituminous mixes. Poor bituminous mixes cause premature failures such as rutting or permanent deformation, cracking, bleeding etc. The design of bituminous mixes should contain certain criteria to prevent premature failures. The mixes designed based on these criteria are generally known as performance based mix design and are gaining popularity in the recent times. Among various types of pavement failures, permanent deformation or …

EFFECT OF FLY- ASH AND CEMENT ON EXPANSIVE SOIL FOR FLEXIBLE PAVEMENT DESIGN
Abstract: Out of the many types of soils that prevail on the Earth’s crust Expansive soils are observed to be highly problematic by nature. Particularly under conditions of loading, these soils are highly prone to fail due to shear, crushing or excessive settlement. These factors end up expansive soils as unsuitable soils for any construction. If the strength of the soil is poor, then soil stabilization is duly needed. Stabilization is …
