“…FMEA was used for the management of failure risks of the sewerage system of Algiers (Benbachir et al, 2022;Cherrared, 2016). Using the FMEA method to classify the BPs, this is an estimate of a criticality index (Ic) of BP studied.…”

This study aims to help the management of the Stormwater Drainage System (SDS) of Bejaia City to manage urban flood problems, i.e., to provide them with tools for a better organization of information on SDS combined with a better optimization of its interventions on the network. Our study is based on a multicriteria analysis of the ?SDS-inundation-Impact? system. We used a multicriteria approach and classified the overflow points called Black Points (BPs) using two methods: Analytic Hierarchy Process (AHP) and Failure Mode, Effect and criticality Analysis (FMEA). The criteria and the evaluation scale were defined on the basis of past observations, expert opinions, and feedback experience. The map of the past flooded areas was made and used to calibrate the two models. We mapped the BPs according to intervention priorities (one to four). The outcomes from both models are greatly comparable to the results of the impact assessment of past floods. The proposed approach can also reduce flood risks by integrating some of influencing factors (causing floodings) and the application can be adapted and implemented in other cities too. Both methods are reliable, particularly the AHP for the most overflowing BPs. They could be advantageously combined to improve decision-making.

To ensure the safety of road users, and in view of the direct contact of vehicles with the surface layer, an in-depth characterization of road pavements would be necessary. For this, the use of porous mixtures has obvious advantages in reducing the flow and infiltration of water into the soil. The main purpose of this study aims to improve the macrotexture and the adhesion of the wearing course, while keeping the level of mechanical performance within the allowable range. That is why artificial grading curve composed of several sub-fractions (twelve in this case) was developed. The volumetric technique by the patch test 13036-1 (Mean Texture Depth) was used to evaluate the macrotexture of mixtures. In addition gyratory compactor was used to determine workability, to evaluate intrinsic characteristic and moisture susceptibility, we performed Duriez test, and Nottingham University to estimate indirect tensile stiffness modulus. The results demonstrated that the use of modified grading curve mixtures improves the performance of the road surface (macrotexture) and keeping their mechanical proprieties. However, a model was developed using fuzzy logic approach aiming to predict compactness and stiffness modulus (SM) of asphalt mixtures as a function of air voids (Va) and Mean Texture Depth (MTD). The results observed that the values obtained by the developed models are acceptable comparing to experimental results.
