摘要：	Rapid industrialization and large scale road infrastructural development in India, has resulted in huge scarcity of Construction materials. There is a thrust to investigate the methodology to reduce the thickness of pavement crust to conserve the conventional construction materials viz. soil and aggregate. This is possible by using chemically (cement) stabilized material in sub grade and sub base layers of road pavement. To investigate this, a 300 m experimental test track was constructed on Amritsar-Wagha border section (near Amritsar) of NH-I which was widened to four lanes divided highway from two lanes. Design and construction was carried out as per MORTH and IRC guidelines. Cement stabilized layers was used on the left side of widening portion (two lanes) of the road towards Wagha Border. In order to compare the performance of cement stabilized road vis-s-vis conventional construction, the test track was divided into two sections. First section was constructed by using conventional local soil/aggregate/bituminous materials. In the second section, local soil and granular sub base materials were stabilized with cement (2.5％) and used for the construction of sub grade and granular sub base layers. The paper presents the design of unstabilised and stabilised pavement layers. Methodology is presented considering the experience gained during the field construction. Quality of construction was evaluated during and after construction by sand replacement method, unconfined compressive strength and plate load test. Modulus of elasticity was also evaluated. Pavement performance observation was carried out by visual inspection and using different equipments like Benkelman beam and dip stick. It was concluded that performance of stabilised and unstabilised sections were comparable even after reduced total thickness of stabilised pavement section.
