Abstract:

 Quantity road aggregates have become rare and costly in many places in India due to massive constructionactivities required for the development of new infrastructure facilities. The pavement industry looks for waysof improving lower quality materials that are readily available for use in roadway construction. Cement/ limetreatment has become an accepted method for increasing the strength and durability of soils and marginalaggregates, reducing quantity of aggregates. Indian Roads Congress (IRC) developed a Special Publication(SP) for mix design of lime/cement treated base/subgrade. No pavement design guideline is presentlyavailable for cement/lime treated base. To overcome this problem, the objective of the present research workis to develop a pavement design chart using cement and lime stabilized base for rural roads with light tomedium traffic (Traffic level up to 5 million standard axles). Based on this objective ,the scope of the present research work is limited to develop a pavement design chart varying California Bearing Ratio (CBR) ofsubgrade and thickness of stabilized material as well as axle load repetition up to 5 million standard axles(MSA).Charts have been developed using FPAVE software. Results indicated that at known particularresilient modulus of stabilized base and CBR of subgrade, thickness of soil-cement base and that of soil-limesub-base increase with increasing the allowable number of load repetitions. Thickness of soil-cement baseand that of soil-lime sub-base decrease as moduli of soil-cement base and soil-lime base increase. For eachmodulus of soil-cement base and soil-lime sub-base, as CBR is increased, thickness of soil-cement base andthat of soil-lime sub-base decreased significantly. At a particular resilient modulus, CBR and N, the thicknessof soil-cement base is less than that of granular base. Finally, design curves have been developed to estimatethickness of soil-cement base and that of soil-lime sub-base for different N-values and different values ofmodulus of soil-cement and soil-lime mix.
