Performance Evaluation of Low-Volume Road Sections Consisting of Enzyme Stabilized Inverted Base
Inverted base pavements are becoming more popular due to its strong base and lower cost of construction compared to conventional pavements. The purpose of the present study is to evaluate the performance of bitumen-surfaced low-volume road sections consisting of conventional and enzyme stabilized inverted base sections. An enzyme-based stabilizer was used to stabilize the lower base of the inverted base pavement section. Performance evaluation studies were carried on four roads located in two districts of Andhra Pradesh. The present study is initiated by hypothesizing that the performance of inverted base pavement sections is same as the performance of the corresponding control sections. The relative performance of inverted base pavement sections is compared with control sections for four roads in terms of roughness, Benkelman beam deflection, rutting, and dynamic cone penetration. The performance in terms of roughness for pavement sections consisting of inverted base is relatively better than the control sections for one road, even though the difference is not significant. However, for the remaining three roads, the performance of control sections is relatively better than the inverted base sections. Based on the Benkelman beam deflection and the rutting data, it is observed that the control sections are performing better than the inverted base sections even though the difference is not significant. The difference in performance between inverted base sections and control sections for different roads is attributed to the prevailing local conditions. Considering the fact that the cost of inverted base sections is lower compared to the conventional pavement sections, the comparable performance of both the pavement types justifies the use of inverted pavement sections for low-volume roads.
