dc.description.abstract | Environmental, performance and life cycle cost analysis of maintenance techniques of asphalt pavements were done. Environmental effects of those techniques were evaluated using PaLATE. A typical section was chosen for each maintenance technique and environmental effects were quantified using PaLATE. For performance evaluation, pavement sections repaired using different maintenance techniques were surveyed and PCI was calculated according to ASTM D 6433-07. ANOVA was used to analyze if there was difference in performance. Life cycle cost analysis was performed using Real Cost, a Excel based program. Inputs used in the program were obtained for the New York CIPR study (22). Based on subjective rankings and input used in our study, CIPR has the least environmental effects followed by TCO, MF, CIPR-AS and TCO-NR. The use of RAP had positive effects on environmental effects and the use of add stone had adverse effects. Performance of the maintenance techniques was not statistically significant. Maintenance technique with least initial cost had least life cycle cost. For LCCA also, the use of add-stone to CIPR had an adverse effect on LCC and addition of RAP to TCO had positive effect. MF was the costliest maintenance technique and would require the longest service lfie to have and equivalent LCC. Further studies are needed to evaluate the positive and adverse effect of use of RAP and add-stone to TCO and CIPR respectively. For our study the performance was not significantly different for maintenance techniques, so the decision was based on environmental effects and LCC. CIPR without add-stone was the best maintenance technique based on those two. | |
