He said that the impregnation took place on Thursday after laboratory tests on the resistance of two layers of the pavement, namely the foundation and base layers to check if the objective is achieved, before the arrival of the ‘bitumen emulsion on Friday, specifying that the first part is already covered with the wearing course.
“The lab will be here first to experiment and see if we’ve hit the target. We must first see the compaction module if we have reached the target, it is at this time that the impregnation takes place this Thursday and Friday will intervene the setting of asphalt of 5 cm and you will have your pavement in good and due form. », Clarified Mr. Mundaya.
He suggested that the work he is leading on this section is part of the operation that had just been launched recently by the Minister of State in charge of Infrastructure and Public Works, Alexis Gisaro Muvunyi and the Governor of Kinshasa city, Gentiny Ngobila Mbaka called « operation zero hole in Kinshasa ».
Ir. Mundaya also pointed out that for Tshangu district, OVD has already started work on Ward 1 at the entrance to Ndjili in its section between the first entrance and Kiluangu Avenue.
Responding to a question on the types of work carried out on the section, Ir. Ali Mundaya indicated that OVD in the process of rehabilitating the road, that is to say treating the foundation layer, the layer of base and the wearing course adding that “apart from the roadway, its office rehabilitates the walls, the gutters, the shoulders of the road and the curbs. Therefore, he rebuilt certain sections in their entirety to facilitate traffic for users and put an end to traffic jams.
Mr. Mundaya also deplored the bad practices on the roadway by users citing among other things the clogging of sanitation structures with rubbish, throwing debris and waste which block the passage of the easy flow of rainwater and housekeeping. Water being the number one enemy of the pavement damages the wearing course by creating potholes and sloughs in the pavement, reducing the life of the road.
« Wherever the gutter is clogged, the road is destroyed, and wherever the water circulates in the gutter, the road is in good condition », he noted while asking users to always keep the gutters clean.
Mr. Mundaya also denounced the repair of vehicles on the road which according to him is prohibited by the road regulations in force in the Democratic Republic of the Congo. « When you seep oils or hydraulic oil on the road, you shorten the life of the road, » he said, while calling on drivers to clear the way for users to pass freely. « We must not let the wastewater from the plots run onto the road, this is prohibited, » he advised.
Responding to a question about the different kinds of footwear, Mr. Mundaya indicated that there are two types of pavements, namely the rigid pavement which is built of reinforced concrete on the basis of cement and the asphalt pavement using asphalt mixes.
Rigid pavement is tolerant of water and has a longer life, 20 to 25 years but at a high cost, compared to flexible bitumen pavement which has a life of 10 to 15 years, if the road is well maintained. The works of this road will last 90 days, it is recalled.
