Low Cost Roads Stabilized by ECOLOPAVI

Jose Francisco Rufino Diogo and Ammar Abbas Mohammed Shubber

Abstract:
This study presents the effect of ECOLOPAVI stabilizer on Low Cost Roads (LCR). This study found that a mix of 2% cement and 5% ECOLOPAVI can improve the bearing capacity (CBR) of clayey soil with CBR = 3% up to 49%; similar result can be get by adding 6% to 7% of cement or lime in conventional practices; that means the combination of ECOLOPAVI with cement or lime can be used to reduce the construction cost of roads. This product is presented as an alternative to other conventional stabilizer in use (cement or lime). In this research, ELSYM 5 program is employed to evaluate and compare two pavement structures with natural subgrade soil and with stabilized subgrade. The pavement response show that it is strongly dependent on subgrade layer elastic or resilient modulus; as the depths increase, the stresses, displacement and strains decreased. The results of two pavements (one with subgrade CBR ≥ 3% and another with subgrade CBR ≥ 12%), show that the structure with subgrade CBR ≥ 12% gave low stress, displacement and strains than that with CBR ≥ 3%.
