How are you sure of the bold?
As a reminder, this is even not the first time roads are being built in Nigeria
.....and back in the day, the stretch from Tinubu Square to Tom Jones (now Nnamdi Azikiwe Street), Lagos, was paved with concrete.
Again, the BRT lanes on Ikorodu Road, Lagos are currently being replaced by paved concrete as an experiment following the "failure" of ashphalt paving.
On another hand, Julius Berget pioneered the inter-locked pavement on Western Avenue several decades ago, and LASG has now being building roads with such in swampy/water catchment areas
as a policy using sharp sand as base as against laterite which collapses easily under ashphalt crack and quickly forms a pot hole.
