For any odd prime p such that pm ≡ 3 (mod 4), the structures of all (α + uβ)-constacyclic codes of length 4ps over the finite commutative chain ring Fpm + uFpm (u2 = 0) are established in term of their generator polynomials. When the unit (α+ uβ) is a square, each (α + uβ)-constacyclic code of length 4ps is expressed as a direct sum of two constacyclic codes of length 2ps
