Concrete Pavers Failing – UNRA

The pilot project for constructing roads using concrete pavers has had negative results.

In March 2011, Uganda National Roads Authority through CHICO Construction Company tarmacked the 41 kilometers Matuuga-Semuto-Kapeeka road stretch at 35 billion shillings.

Uganda National Roads Authority used concrete pavers on some sections of road as a pilot study, with the hope of cutting costs. Dan Alinange, the spokesperson Uganda National Roads Authority says during the study period they were testing the strength, durability and response of the concrete to the environment as compared to bitumen.

He says they opted to try out the concrete pavers in road construction because they are cheaper and widely used in developed countries. Alinange however, says their experiment has had negative results. He says the concrete pavers have not worked to their expectations as they have caved in. Alinange says that they are also carrying out road tests in Northern Uganda and want to compare the findings before they reach a conclusion on whether or not the pavers can be used in Uganda.

He says a team of UNRA engineers are still investigating why the pavers have not worked well adding that they will make recommendations once their work is complete. Moses Ssenfuma, the LC 3 chairperson Kapeeka Sub County says residents are worried about the general state of the road because it has developed defects few years after completion. Ssenfuma says UNRA underestimated the trucks that use the road such as trucks that ferry military hardware to Singo Military Training School.

The LC 3 chairperson says he has already notified UNRA about the defects on the road. James Musisi, a resident of Kanyanda village says the pavers and tarmac are being washed away at high rate adding that they were of poor quality. Musisi says that they are skeptical weather there was value for money because the road has developed potholes within such a short time after completion. Ignatius Koomu, the Nakaseke LC V chairperson says that they have also seen the defects, but says they were never consulted so they don’t what exactly should have happened.

He has appealed to UNRA to correct the defects.
